JUSTICE DOUGHERTY

OPINION

This is a direct capital appeal from an order dismissing a petition filed pursuant to the Post Conviction Relief Act (PCRA), 42 Pa.C.S. §§ 9541 - 9546, following an evidentiary hearing limited to one issue. Appellant Ricardo Natividad presents the Court with multiple challenges pursuant to Brady v. Maryland , 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963) (prosecution must disclose evidence favorable to the accused that is material either to guilt or punishment), none of which afford him relief. We therefore affirm the order dismissing appellant's petition.

I. Background

We previously set forth the underlying facts in our opinion affirming the judgment of sentence. Commonwealth v. Natividad , 565 Pa. 348, 773 A.2d 167, 171-73 (2001) ( Natividad I ) (Opinion Announcing the Judgment of the Court), cert. denied , 535 U.S. 1099, 122 S.Ct. 2300, 152 L.Ed.2d 1056 (2002). As these facts are directly relevant to the Brady claims raised in this appeal, we recite them again at some length:

The evidence presented at trial established appellant's involvement in certain activities beginning at 2:00 a.m. on November 9, 1996 and continuing through to approximately 11:00 p.m., November 9, 1996. About 2:00 a.m. on November 9, 1996, Michael Havens stopped to get a sandwich at Philly's Famous Cheesesteaks at the intersection of Island and Elmwood Avenues in Philadelphia. Upon returning to his car with the sandwich, Mr. Havens was approached by two men. Mr. Havens'[s] car was a dark blue Lincoln that he recently had purchased. As Mr. Havens was entering the combination to unlock the front driver's door of the Lincoln, appellant interrupted Mr. Havens by pointing a stainless steel revolver

with rubber grips at him. Another man, acting in concert with appellant, approached Mr. Havens at the same time, standing behind him while appellant faced him with the gun. Mr. Havens gave his wallet and car keys to appellant. Appellant ordered Mr. Havens into the car. When Mr. Havens hesitated, appellant threatened to kill him in the parking lot if he refused to get into the car.

Mr. Havens sat in the back seat of the car. Appellant sat in the front seat of the car on the passenger side. Appellant sat facing Mr. Havens, with the gun aimed at Mr. Havens throughout the time they were in the car. Appellant's accomplice drove the vehicle. Over the next fifteen to twenty minutes, appellant repeatedly threatened to shoot Mr. Havens while demanding more money from him. Mr. Havens gave appellant and his accomplice the cash from his pocket and begged to be released from the vehicle. Appellant requested Mr. Havens'[s] money access card and that Mr. Havens access the account to get them additional funds. Mr. Havens responded that there was no money in the account as he had just paid bills. Appellant continued to threaten Mr. Havens with the firearm. Finally, the men pulled the car to the side of the road. Mr. Havens was ordered out of the car and told to prepare to die by appellant. Appellant directed Mr. Havens to turn his back and remain standing. While Mr. Havens complied, appellant fled. Upon realizing that he was alone, Mr. Havens walked to a nearby store, called for assistance and reported the incident to police.

At approximately 7:00 p.m. on the evening of November 9, 1996, appellant, driving a blue Lincoln, met his friend, Byron Price, near 60th and Catherine Streets in Philadelphia. Mr. Price testified that this was the first time he had seen appellant in possession of a dark blue Lincoln. The two men planned to spend the evening together watching a boxing match. Mr. Price sat in the passenger seat of the Lincoln; appellant drove. Appellant pulled the car into an EXXON gasoline station at the corner of 60th and [Vine] Streets. Appellant told Mr. Price to wait. While sitting in the car, Mr. Price heard a gunshot. Appellant ran back to the car with a chrome revolver in his hand. Mr. Price noticed that a man he had formerly observed standing by a car in the gas station was now lying on the ground. Dropping the gun in his lap, appellant quickly made a U-turn out of the EXXON station and sped away on 60th Street. Mr. Price asked appellant why he shot the man. Appellant replied, "he drew on me."

Mr. and Mrs. Johnson had been leaving their home across the street from the EXXON station at the time of the shooting. They were unable to identify appellant; however, they testified that the shooter left the EXXON station in a dark Lincoln. They each, independently, testified to the following observation: the victim raised his hands in the air and then fell backwards at the same time that a gunshot was heard. The shooter was wearing a lumberjack style jacket at the time of the incident. After the gunshot, the shooter jumped into the driver's side of a dark Lincoln and sped away on 60th Street.

On November 11, 1996, Philadelphia police recovered a dark blue Lincoln that had been abandoned and set on fire. From the trunk of the car, the police recovered a lumberjack style jacket. Mr. Havens identified the burnt Lincoln as the car appellant had stolen from him at gunpoint on the morning of November 9, 1996. Mr. Havens also identified the jacket recovered from the trunk of the

car as his own jacket that he had left in the car at the time of the robbery.

The day after the murder, appellant made statements to several of his acquaintances taking credit for having shot the man at the EXXON station. Several weeks after the incident, appellant approached his friend Keith Smith while Mr. Smith was helping Carl Harris wash Mr. Harris's car. Mr. Harris testified that he observed Mr. Smith and appellant engage in a conversation, out of his hearing, and then walk around the corner from where Mr. Harris was standing. When Mr. Smith returned after parting from appellant, Mr. Smith had in his possession a chrome .357–Magnum firearm. Sometime in December of 1996, Mr. Smith gave a .357 revolver to his attorney, Mr. Spina. Attorney Spina immediately notified Philadelphia homicide detectives that he had the gun in his possession. The homicide detectives recovered the revolver from Mr. Spina's office and turned it over to the Philadelphia crime lab for testing.

Based on information received in their investigation, the police obtained an arrest warrant for appellant in December of 1996. However, it was not until March 17, 1997 that appellant was apprehended. Following appellant's arrest, Mr. Havens, the victim of the robbery of the Lincoln, came to the police station to view a photographic array. Upon viewing the array, Mr. Havens positively identified a photograph of appellant.

The results of forensic and pathology reports revealed that Mr. Campbell had been shot in the head at a distance of at least two feet causing his immediate death. The fatal wound was consistent with the type of injury caused by a .357 Magnum firearm. The .357 Magnum obtained by police from the office of Mr. Spina had been fired prior to being handed over to the police. Mr. Havens identified the gun recovered from Mr. Spina's office as identical to the gun held on him by appellant during the robbery of his motor vehicle. Mr. Price identified the gun appellant possessed after shooting Mr. Campbell as similar in appearance to the gun Mr. Spina delivered to the Philadelphia police.

Id. (citations to trial transcripts omitted).

Appellant was charged in separate indictments for the robbery of Michael Havens and the murder of Robert Campbell. The indictments were consolidated for trial. On November 10, 1997, a jury convicted appellant of first-degree murder, carrying a firearm on a public street, two counts of possession of an instrument of crime, two counts of robbery, one count of robbery of a motor vehicle, kidnapping, and criminal conspiracy. At the penalty phase, the jury returned a verdict of death after finding the aggravating circumstances — killing while in the perpetration of a felony, 42 Pa.C.S. § 9711(d)(6), and a significant history of violent felony convictions, 42 Pa.C.S. § 9711(d)(9) — outweighed the sole mitigating factor, appellant's life history, 42 Pa.C.S. § 9711(e)(8). After the trial court denied appellant's post-verdict motions, it imposed a sentence of death for the first-degree murder conviction, and imposed additional sentences for the other charges to run concurrent to the sentence of death.

On automatic direct appeal pursuant to 42 Pa.C.S. §§ 722(4) and 9711(h)(1), this Court rejected appellant's five claims of trial court error in an Opinion Announcing the Judgment of the Court. Natividad I , 773 A.2d at 181. Thereafter, on November 25, 2002, appellant filed a first pro se PCRA petition. Counsel was appointed and filed an amended petition, raising twelve claims of ineffective assistance of trial counsel, trial court error, and prosecutorial misconduct. Following a two-day evidentiary hearing limited to appellant's allegations of ineffective assistance of penalty-phase counsel, the PCRA court denied the petition. This Court affirmed the order denying PCRA relief on December 27, 2007. Commonwealth v. Natividad , 595 Pa. 188, 938 A.2d 310 (2007) ( Natividad II ).

Appellant filed a second pro se PCRA petition on March 11, 2008, challenging PCRA counsel's stewardship in handling his first PCRA petition. On November 14, 2011, the PCRA court dismissed the second petition as untimely. Appellant did not seek further review of that order.

On June 27, 2008, appellant, now represented by the Federal Community Defender Office (FCDO), filed a petition for a writ of habeas corpus in the United States District Court for the Eastern District of Pennsylvania. Natividad v. Beard , No. 08-cv-0449 (E.D. Pa.). As part of that litigation, appellant sought discovery from the Commonwealth. Following informal negotiations over the course of several years, appellant eventually filed a formal motion for discovery in the federal court, seeking access to the Commonwealth's internal trial file, as well as the investigating homicide detective's file, or "H-file." The Commonwealth opposed the motion.

On August 19, 2011, the federal court ordered the Commonwealth to produce certain discovery, but denied appellant's request for access to the entire trial and investigatory files in the possession of the Commonwealth and the police. In response to the court's order, the Commonwealth turned over more than 200 pages of documents to appellant on March 6, 2012. See Appellant's Third PCRA Petition, 8/9/2012, 3 ¶ 10. Among those disclosed documents was a piece of paper with several roughly handwritten notations, including the following entry:

5635 BELMAR DOERS LEFT IN SW + GOT TAG# 727-8853 JOHN `MACULLA' B/M 40's STOCKY, REDDISH HAIR &sign; TOLD MANAGER ON SUNDAY &sign; 5'11 LT COMP THAT HE WAS ON LOT + SAW INCIDENT

Id. at 3 ¶ 11; Exhibit B to Appellant's Third PCRA Petition (the "Maculla" note).

On June 13, 2012, over three months after the Commonwealth disclosed the "Maculla" note, an investigator hired by appellant's counsel interviewed a "John McCullough." See Response in Opposition to the Commonwealth's Motion to Dismiss, 8/27/2014, 3. Subsequently, on July 19, 2012, McCullough signed a declaration in which he asserted the following under penalty of perjury:

1. One day in 1996, I was driving to a laundromat on 63rd Street in West Philly. I was working as a security guard at another laundromat at 60th and Cedar and had been offered part time work at the one at 63rd and Vine. That day, my 14 year old son and I had stopped by a funeral home at 63rd and Oxford. On the way home, we stopped by the laundromat at the Exxon gas station on 63rd Street.

2. I parked my car and just as we got out of the car, I noticed three men about three cars away. One guy was tall and light skinned. He was the victim. There were two darker skinned guys there. One guy was facing the victim and had his hands on the victim's shirt. There was another

guy standing to the side with a gun. I froze in my tracks so as not to draw attention to myself or my son. I stood there looking at the three men for what seemed like one and a half minutes.

3. All of a sudden, the victim pushed the guy in front of him away and I heard one or more gunshots. I then saw the two darker guys run toward an already running car. The car was dark colored.

4. After the shooting, the police came to the laundromat and I told them what I saw. At first the police were suspicious of me because I was standing so close to the crime, but did not get hurt. I was asked if I knew either of the two dark skinned men, but I said that I did not. They seemed to imply that I must have known them or else I would have been shot, too. After a while, my son and I were taken to 55th and Pine to give a statement. We sat in a hallway at the station waiting to talk to a detective. As we were waiting, we started talking to a man and woman who saw the incident and were waiting to talk to the detectives too.

5. I talked to a detective at 55th and Pine and signed a 2½ page written statement about what I saw.

6. Sometime after the incident on 63rd Street, I became ill with a heart problem. Because of this illness, I left Philadelphia for a while to visit my sister in Virginia. While I was in Virginia, I received a long distance telephone call from a neighbor who said that there had been what looked like policemen coming by my house on Belmar Terrace. I called and left a message for the police telling them where I was. I received a return call from the police and, after I explained that I was ill and would return home after I recuperated, the policeman said they would wait until I returned.

7. When I returned to Philadelphia, some police came by my house. They asked me if I had spoken to anyone about what I saw that night. I replied that I had been in Virginia and had not spoken to anyone. They told me that they had "got the guy" and that they were "looking for the second guy." They said that they took care of everything and did not need me.

8. I used to work for the Greater Philadelphia Urban Affairs Coalition running summer programs for at risk youths. During one summer, [appellant] was in my programs. I got to know him and would recognize him if I saw him. Only recently did I find out that [appellant] was in prison for committing the killing I saw.

9. [Appellant] was not one of the two men that I saw with the victim at the laundromat at 63rd and Vine Street[s].

Declaration of John McCullough, attached as Exhibit D to Appellant's Third PCRA Petition, 8/9/2012.

After obtaining McCullough's declaration, appellant filed the instant third PCRA petition on August 9, 2012. In his petition, appellant alleged the Commonwealth violated Brady and its progeny because it "never produced a written statement" that McCullough claimed in his declaration he gave to a detective shortly after the murder, and because it "had not even produced the note mentioning John ‘Maculla[.]’ " Appellant's Third PCRA Petition, 8/9/2012, 6 ¶ 20. With regard to the "Maculla" note, appellant asserted its indication that McCullough "got" the tag number of the shooter's vehicle was favorable and material because the Commonwealth alleged at trial that the car stolen from Michael Havens was the same car witnesses identified as belonging to the shooter and, thus, it "provided the evidentiary link between the two crimes." Id. at 6-7 ¶ 23. According to appellant, if he "had received evidence that a different car was involved in the shooting, he would have used it to refu[t]e the inferences of identity and motive ... and challenge the joinder of the two cases." Id. at 7 ¶ 25.

Although appellant recognized his third petition was facially untimely, he alleged it met two timeliness exceptions set forth in the PCRA. Id. at 10 ¶ 32. First, he asserted his Brady claim could not have been raised sooner "as a result of government interference with the production of exculpatory information in this case." Id. , citing 42 Pa.C.S. § 9545(b)(1)(i) ("the failure to raise the claim previously was the result of interference by government officials with the presentation of the claim in violation of the Constitution or laws of this Commonwealth or the Constitution or laws of the United States"). Second, he argued his claim was timely pursuant to 42 Pa.C.S. § 9545(b)(1)(ii) ("the facts upon which the claim is predicated were unknown to the petitioner and could not have been ascertained by the exercise of due diligence"), because the Commonwealth's production of the note "led to John McCullough." Id. Regarding Section 9545(b)(2)'s requirement that "[a]ny petition invoking an exception provided in paragraph (1) shall be filed within 60 days of the date the claim could have been presented[,]" appellant averred he satisfied this requirement by filing his petition "within 60 days of the date that Mr. McCullough signed the [d]eclaration, July 19, 2012, and within 60 days of the date that [appellant]'s investigator first spoke with Mr. McCullough, June 13, 2012." Id. at ¶ 33.

The Commonwealth filed a motion to dismiss appellant's petition on March 18, 2014, alleging the petition was untimely and meritless. With respect to timeliness, the Commonwealth argued appellant failed to raise his Brady claim within 60 days of the date it could have been raised, as required by Section 9545(b)(2). See Commonwealth's Motion to Dismiss, 3/18/2014, 19. In the Commonwealth's view, appellant was "required to file his petition within sixty days of March 6, 2012[,]" the date the Commonwealth turned over the "Maculla" note. Id.

On the merits, the Commonwealth argued the note was not material evidence that it was required to disclose under Brady since "[t]he notation on the scrap of paper does not reflect that ‘John Maculla’ identified the shooter — let alone that he identified the assailant as someone other than [appellant]." Id. at 17 (emphasis in original). Invoking prior pronouncements by this Court that there is no constitutional requirement that a prosecutor "make a complete and detailed accounting to the defense of all police investigatory work on a case," Commonwealth v. Appel , 547 Pa. 171, 689 A.2d 891, 907 (1997) (citation omitted), the Commonwealth maintained it "had no duty under Brady to disclose to the defense this tattered scrap of paper from the police homicide file" which "merely reflects one of many investigatory leads in this case." Id.

While appellant's PCRA petition was pending in the PCRA court, appellant filed a supplemental discovery motion in federal court, again seeking access to the complete trial and investigatory files of the Commonwealth and the police. On July 9, 2014, the federal court granted appellant's request, and the Commonwealth made additional files available to appellant on August 7, 2014.

This second production of documents yielded previously undisclosed statements of three individuals: Joseph Rutherford, Cynthia Smith, and Rolston Ricardo Robinson. All three statements were taken on November 14, 1996 — five days after the murder.

Rutherford indicated in his statement that after he was released from incarceration on November 4, 1996, he went to a house located at 929 Wynnewood Road in Philadelphia with his friend Edward Maloney. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 1 pp.1-2. Michael Cupaiuolo owned and lived at the house with his girlfriend "Cindy." Id. at 1. When Rutherford and Maloney arrived, Robinson was present, as was Kenny Hart. Id. at 2. Rutherford described Robinson as "a Jamaican male [who] sells crack" and "likes intimidating people." Id. That morning, Robinson offered to front Rutherford $40 worth of crack if Rutherford agreed to pay him $80 in return by noon. Id. Rutherford and Robinson "had some words" about the payment before Robinson warned Hart "it was on him" to make sure Rutherford paid in full. Id. When Rutherford met Hart later that day, he produced only $50, and instructed Hart to send a message to Robinson that "this was all he's getting." Id. Rutherford returned to Cupaiuolo's house the following day, at which point Robinson came outside and threatened to knock out the windows on Rutherford's car unless he paid him the remaining $30. Id. at 3. Rutherford told Robinson he would see him later and left. Id.

The next day, November 11, 1996, Rutherford was at his girlfriend's house when Robinson and another individual showed up with a hammer and demanded the $30. Rutherford's girlfriend paid Robinson the money. Id. Later that night, Rutherford went to Cupaiuolo's house where he got into an argument with Robinson and threatened to kill him. Id. at 3-4. Robinson responded that he would "do [Rutherford] like he did Bob down at the gas station." Id. at 4. Rutherford noted in his statement "[t]here was already some talk in the neighborhood about [Robinson] having something to do with Bob Campbell's killing." Id. at 3.

The dispute between Rutherford and Robinson escalated again on the night of November 13, 1996. Id. at 4. Rutherford was standing outside a bar at 66th and Lebanon Streets when Robinson and two others pulled up in a car. Id. Rutherford and Robinson "had words" before Rutherford walked back into the bar. Id. A few minutes later, Maloney walked in and told Rutherford that Robinson and the other men were upset with Rutherford and had guns. Id. At that point, Rutherford told "the entire bar that these were the guys the cops suspected of killing Bob." Id. The bartender told Rutherford to call 9-1-1, which he did. Id. Eventually, police arrived, and Rutherford accompanied them to Cupaiuolo's house to locate Robinson. Id. at 5. When Robinson drove by and saw the police he sped off, but the officers pursued and eventually stopped him. Id. In his statement taken the next morning, Rutherford indicated "Cindy" had also "heard Rob discussing" the murder, and that Cupaiuolo "thought Rob had something to do with it." Id. He further stated he had previously seen Robinson in a black Lincoln, but he did not know where it was or where it came from. Id. at 6.

Smith explained in her statement that Cupaiuolo often let people stay in their house at 929 Wynnewood Road, including Robinson. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 2 p.1. She stated she learned of the victim's death shortly after it happened, when Robinson came into the house and turned on the news. Id. at 2. When Smith asked Robinson what he was doing, he replied: "[T]his is important. Didn't you hear about the guy getting shot — down at the gas station[?] You know the guy — the fucking snitch — that town watch guy Bobby Campbell." Id. Robinson continued discussing the news story until he left the house. Id. at 3. When he returned an hour later, he told Smith he had been at the scene and saw the victim had a gun and was bleeding. Id. He stated to Smith that he "stood over top of the guy saying ‘You dumb fuck.’ " Id. On the afternoon of November 13, 1996, Smith asked Robinson if he had anything to do with the murder, to which he responded, "Yeah — I did it." Id. at 3-4. Robinson further stated "that's what happens to snitches," and that he "had to teach somebody a lesson." Id. at 4. After making these statements Robinson left the house, but returned approximately fifteen to twenty minutes later and offered to "loan [Smith] money for [ ] dope." Id. at 4. Smith felt as if Robinson was "trying to buy [her] off." Id.

Robinson also gave a statement to police on November 14, 1996. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 3. He stated he went to the Turf Club with his friend "C" around 7:45 p.m. on the night of the murder. Id. at 2. While there, Robinson bet on some horses over the course of a few hours. Id. When they left, Robinson passed by 63rd and Vine Streets, where he saw police at the gas station and a man lying on the ground. Id. He parked his car by one of the gas pumps. Id. There were five to ten people near the gas station, and a detective asked if anyone saw anything; Robinson heard an African American female state, "they left in a Black Lincoln." Id. Robinson saw the victim was "[a] white male, laying on [the] ground on his back, [with] blood near his shoulders." Id. at 3. He also noted the victim was wearing a jacket and had a gun in a holster on his waist. Id. Robinson explained he stopped at the gas station because he saw the police cars, people standing around, and a body on the ground. Id. He stated he stayed for only two or three minutes, and that he knew nothing about the murder. Id. at 3, 6.

The Commonwealth also produced certain police investigatory paperwork that had not previously been turned over to the defense and which referenced Robinson. Officer Rita Wilson described in a statement that she responded to the dispute between Rutherford and Robinson at the bar on 66th and Lebanon Streets. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 8 p.1. She noted Rutherford told her that "Rob" had stated "we're going to do to you what we did to the guy at 63rd and Vine."Id. at 2.

Officer Shane Darden explained in his statement that around 4:00 a.m. on November 14, 1996 — only hours after Rutherford had given his statement to homicide detectives — Rutherford stopped him on the street and told him he had additional information about the homicide. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 7 p.1. Rutherford directed Officer Darden to Cupaiuolo's house, where the officer encountered Cupaiuolo and Tracie Durham. Id. Cupaiuolo explained to Officer Darden that Robinson had been telling people in Cupaiuolo's house he "was there when Campbell was shot." Id. Durham stated she was on a pay phone near the gas station about ten minutes prior to the homicide and saw Robinson drive by twice in a gray sedan. Id. at 2.

A police activity sheet prepared by the assigned homicide detective and dated November 13, 1996, also mentioned Robinson. See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 5 p.1. It stated, in relevant part:

The assigned was contacted by a retired Detective who related that he had been contacted by an old informant who related that persons in 929 Wynnewood Rd. may have information as to the identity of the perpetrator and that he may be named ROB and was a Jamaican male. Det. DiBlasi & the assigned set up a surveillance of this location and noted that a B/M left the location and drove away in a 1988 Acura painted gray. The license tag was checked thru [sic ] BMV and it was registered to a RUPERT ROBINSON at [redacted]. This male fit the general description of the male called ROB. It was also noted that adults aged 20 to 40 both white and black were coming and going from this location. The Detectives stopped one of these persons and learned that ROB does operate the gray Acura and several persons in the location were upset with him over drug matters.

Id.

Two additional statements included in the Commonwealth's production were also never previously disclosed to the defense. On November 14, 1996, Tracie Durham, after previously speaking with Officer Darden at Cupaiuolo's house, gave a statement in which she stated she did not know about the killing but "was told by Joe [Rutherford] ... that a guy name[d] Rob ... did it." See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 4 p.1. She again explained she was on a pay phone outside the gas station around 9:50 p.m. on November 9, 1996, when she saw a car that "looked like Rob's silver Lexus and a gentleman that looked like Rob driving it." Id. She asserted she did not see the victim at the gas station. Id. at 2.

Finally, on November 12, 1996, Richard Anderson gave a statement to police in which he stated he was not at the gas station on the night of the shooting, but that he heard from a female named Tish that another man told her people who lived at "the house at [929 Wynnewood Road] ... [and] call themselves the Junior Black Mafia had something to do with the shooting of Mr. Campbell." See Appellant's Supplement to Third PCRA Petition, 10/6/2014, Exhibit 6 pp.2-3. Anderson also stated he had walked by a group of teenagers on November 10, 1996, and heard one of them say they thought it was the Junior Black Mafia who did it; Anderson took "it" to mean the shooting at the gas station. Id. at 4.

Based on the Commonwealth's disclosure of these various statements and documents, appellant sought leave to amend his third PCRA petition to include an additional Brady claim on October 6, 2014, and leave was subsequently granted without objection by the Commonwealth. N.T. 7/7/2016, 61-63. As stated by appellant, the withheld materials "identify a Rob as not only a suspect, but as the confessed killer of the victim in this case." Appellant's Supplement to Third PCRA Petition, 10/6/2014, 5 ¶ 17. Thus, appellant alleged, the materials "[a]lone, and in combination with the declaration of John McCullough that [appellant] was not the person who shot [the victim]," created "a reasonable probability of a different outcome in this trial if the Commonwealth had timely produced the evidence" to the defense. Id. at 12 ¶ 27. Regarding the timeliness of his new Brady claim, appellant again asserted it satisfied both the governmental interference and newly-discovered fact exceptions to the PCRA's time-bar. Id. at 16 ¶ 45, citing 42 Pa.C.S. § 9545(b)(1)(i) and (ii). He further argued his supplemental petition was filed within 60 days of the date the Commonwealth disclosed the second batch of documents. Id. at ¶ 46.

On February 11, 2015, the Commonwealth filed a supplemental motion to dismiss. In relevant part, the Commonwealth argued appellant's new Brady claim failed because the leads identified in the second production of documents amounted to "nothing more than inadmissible hearsay and unsubstantiated gossip and rumor about possible suspects that police heard within the first few days after the victim's shooting[,]" each of which "police quickly eliminated ... as having anything to do with the victim's murder." Commonwealth's Supplemental Motion to Dismiss, 2/11/2015, 21.

Appellant filed a reply to the Commonwealth's supplemental motion to dismiss on May 15, 2015, challenging the Commonwealth's authority to be the "sole arbiter of what investigatory leads are true or false and which witnesses are credible and which ones are not." Appellant's Reply in Support of Supplement to Third PCRA Petition, 5/15/2015, 5. Appellant further disputed the Commonwealth's position the withheld evidence was not material. In his view, the Commonwealth "deprived [him] of exculpatory evidence from at least three separate sources, John McCullough, Joseph Rutherford and Cynthia Smith[,]" which evidence was material because it "exonerates him in the homicide of Robert Campbell." Id.

On November 30, 2015, the PCRA court granted an evidentiary hearing limited to the timeliness of appellant's initial Brady claim predicated on the "Maculla" note. N.T. 11/30/2015, 38. The PCRA court conducted the hearing over the course of three days — April 28, 2016, May 20, 2016, and July 7, 2016. At the hearing, appellant presented only McCullough as a witness. The Commonwealth, in turn, presented John McCullough III (McCullough's son), Detective James Dougherty (the assigned homicide detective), and Assistant District Attorney Jason Harmon.

On June 17, 2016, before the PCRA court ruled on appellant's Brady claims, appellant filed a second motion to supplement his PCRA petition, which the court also granted. In that supplemental petition, appellant alleged that, pursuant to Johnson v. United States , ––– U.S. ––––, 135 S.Ct. 2551, 192 L.Ed.2d 569 (2015), "the aggravating circumstance invoked in support of [appellant]'s death sentence, 42 Pa.C.S. § 9711(d)(9), is invalid because it is unconstitutionally vague under the Eighth and Fourteenth Amendments to the United States Constitution." Appellant's Second Supplement to Third PCRA Petition, 6/17/2016, 4 ¶ 9. In support of the timeliness of the claims raised in his second supplemental petition, appellant relied on 42 Pa.C.S. § 9545(b)(1)(iii) ("the right asserted is a constitutional right that was recognized by the Supreme Court of the United States or the Supreme Court of Pennsylvania ... and has been held by that court to apply retroactively"), and argued his petition was filed "within sixty days of the date of the Supreme Court's opinion in Welch [v. United States , ––– U.S. ––––, 136 S.Ct. 1257, 194 L.Ed.2d 387 (2016) ], which expressly made Johnson retroactive." Id. at 6 ¶ 14. The Commonwealth opposed this second supplemental petition as well.

On July 14, 2016, following oral argument by the parties, the PCRA court denied relief as to appellant's original Brady claim concerning the "Maculla" note. N.T. 7/14/2016, 61. In so doing, the court explained it had credited the Commonwealth's witnesses and disbelieved John McCullough's testimony. Id. at 60-61.On July 26, 2016, appellant requested the PCRA court revoke its July 14th order denying relief, on the basis the court had yet to adjudicate the vagueness challenge presented in appellant's second supplemental petition. The following day, the PCRA court vacated its July 14, 2016 order. Over the ensuing months, the parties filed multiple briefs related to appellant's second supplemental petition.

By order dated December 21, 2016, the PCRA court dismissed appellant's Brady claims as untimely and meritless, but granted penalty phase relief on appellant's claim the Section 9711(d)(9) aggravator — a significant history of violent felony convictions — was unconstitutionally vague. The Commonwealth filed a motion for reconsideration.

On January 13, 2017, the PCRA court vacated its prior order granting penalty phase relief. Thereafter, on February 14, 2017, it denied relief as to all claims raised in appellant's third PCRA petition and the supplements thereto. Appellant subsequently filed in this Court an appeal from the denial of collateral relief, which is now before us for disposition.

II. Issues & General Principles of Law

Appellant presents five issues for our review: (1) whether the Commonwealth violated Brady when it withheld the note identifying John "Maculla" as an eyewitness to the homicide; (2) whether the Commonwealth violated Brady when it withheld evidence that another person had confessed to the killing; (3) whether appellant was prejudiced by the cumulative effect of the Commonwealth's Brady violations; (4) whether appellant's death sentence should be vacated because it is supported by an unconstitutionally vague aggravating circumstance; and (5) whether the PCRA court abused its discretion by failing to grant appellant's request for the parole and probation files of John McCullough III for purposes of the PCRA evidentiary hearing. Appellant's Brief at 1-2.

In reviewing the denial of PCRA relief, we examine whether the PCRA court's determinations are supported by the record and are free of legal error. Commonwealth v. Spotz , 610 Pa. 17, 18 A.3d 244, 259 (2011). The PCRA court's credibility determinations, when supported by the record, are binding on this Court; however, we apply a de novo standard of review to the PCRA court's legal conclusions. Id.

To be eligible for post-conviction relief, a petitioner must prove by a preponderance of the evidence that his conviction or sentence resulted from one of several enumerated circumstances, see 42 Pa.C.S. § 9543(a)(2), and that the claims have not been previously litigated or waived, see 42 Pa.C.S. § 9543(a)(3). "A PCRA petition, including a second or subsequent petition, must be filed within one year of a final judgment, unless the petitioner alleges and proves that he is entitled to one of three exceptions to this general rule, and that the petition was filed within 60 days of the date the claim could have been presented[.]" Commonwealth v. Edmiston , 619 Pa. 549, 65 A.3d 339, 345 (2013), citing 42 Pa.C.S. § 9545(b). These limitations are mandatory and jurisdictional in nature. Commonwealth v. Taylor , 620 Pa. 429, 67 A.3d 1245, 1248 (2013) (citations omitted).

III. Brady Claims

Due process is offended when the prosecution withholds evidence favorable to the accused where the evidence is material either to guilt or to punishment, irrespective of the good faith or bad faith of the prosecution. Brady , 373 U.S. at 87, 83 S.Ct. 1194. "There are three components of a true Brady violation: The evidence at issue must be favorable to the accused, either because it is exculpatory, or because it is impeaching; that evidence must have been suppressed by the State, either willfully or inadvertently; and prejudice must have ensued." Strickler v. Greene , 527 U.S. 263, 281-82, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999).

Pursuant to Brady and its progeny, the prosecutor "has a duty to learn of any favorable evidence known to the others acting on the government's behalf in the case, including the police." Kyles v. Whitley , 514 U.S. 419, 437, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995). However, there is "no constitutional requirement that the prosecution make a complete and detailed accounting to the defense of all police investigatory work on a case." Moore v. Illinois , 408 U.S. 786, 795, 92 S.Ct. 2562, 33 L.Ed.2d 706 (1972). "The mere possibility that an item of undisclosed information might have helped the defense, or might have affected the outcome of the trial, does not establish ‘materiality’ in the constitutional sense." United States v. Agurs , 427 U.S. 97, 109-10, 96 S.Ct. 2392, 49 L.Ed.2d 342 (1976).

Instead, "favorable evidence is material, and constitutional error results from its suppression by the government, if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different." Kyles , 514 U.S. at 433, 115 S.Ct. 1555 (quotation and citation omitted). "A ‘reasonable probability’ is a probability sufficient to undermine confidence in the outcome." United States v. Bagley , 473 U.S. 667, 682, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985). In evaluating whether a reasonable probability of a different outcome has been demonstrated, "[t]he question is not whether the defendant would more likely than not have received a different verdict with the evidence, but whether in its absence he received a fair trial, understood as a trial resulting in a verdict worthy of confidence." Kyles , 514 U.S. at 434, 115 S.Ct. 1555. A defendant thus "need not demonstrate that after discounting the inculpatory evidence in light of the undisclosed evidence, there would not have been enough left to convict." Id. at 434-35, 115 S.Ct. 1555. Rather, a defendant need only show that the favorable evidence "could reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict." Id. at 435, 115 S.Ct. 1555.

With these general principles relevant to our review in mind, we turn to appellant's Brady claims.

A. The "Maculla" Note

Appellant first claims the Commonwealth violated Brady by failing to disclose to the defense the note referencing John "Maculla," a putative eyewitness to the murder. Appellant's Brief at 14. According to appellant, "the withheld note about John ‘Maculla’ affected [his] preparation for trial" because "[i]t would have led him to Mr. McCullough who in turn would have testified that he saw the shooting, knew [a]ppellant, and [a]ppellant was not one of the people involved in the shooting."Id. at 20.

Before addressing the merits of this claim, we must first determine if we have jurisdiction to do so. See Commonwealth v. Stokes , 598 Pa. 574, 959 A.2d 306, 310 (2008) (merits of Brady claim may not be addressed until it is established petition was timely filed). Appellant filed the instant PCRA petition, his third, on August 9, 2012 — well after his judgment of sentence became final. Recognizing his petition was untimely on its face, appellant argued below that the alleged Brady violation fell within the timeliness exceptions set forth at 42 Pa.C.S. § 9545(b)(1)(i) and (ii). See Appellant's Third PCRA Petition, 8/9/2012, 10 ¶ 32. More specifically, appellant alleged the Commonwealth interfered with his ability to bring his Brady claim by withholding the note prior to trial, and by refusing to turn it over until the federal court ordered the Commonwealth to produce it. Id. Appellant noted in his petition that, in a letter dated April 17, 1997, the Commonwealth represented to the defense it had voluntarily turned over "the names and addresses of all eyewitnesses[.]" See Appellant's Third PCRA Petition, 8/9/2012, 2-3 ¶ 7-8. Appellant further asserted his petition satisfied the newly-discovered fact exception, since the disclosure of the note led to appellant's investigator "finding John McCullough who provided a written statement on July 19, 2012." Id. at 10 ¶ 32. Appellant continued that his petition also met Section 9545(b)(2)'s separate requirement that the petition be filed within 60 days of the date the claim could have been presented, as it was filed within 60 days of the date appellant's investigator first spoke with, and then obtained a declaration from, McCullough. Id. at ¶ 33.

The Commonwealth contested the timeliness of appellant's petition in its motion to dismiss. As particularly relevant here, with respect to Section 9545(b)(2)'s requirement that the petition be filed within 60 days of when the claim could have been raised, the Commonwealth argued appellant was required to file his petition within 60 days of March 6, 2012, the date it turned over the "Maculla" note. See Commonwealth's Motion to Dismiss, 3/18/2014, 19. Thus, because appellant did not file his petition until August 9, 2012 — more than three months after the 60-day period had elapsed — the Commonwealth argued it was untimely. Id.

In response, appellant countered that "[n]o claim could have been raised" prior to locating McCullough because "[t]he disclosure of the name[ ], without more, is not by itself exculpatory and would not give rise to a Brady claim." See Response in Opposition to the Commonwealth's Motion to Dismiss, 8/27/2014, 3. Instead, he argued, "[i]t was not until [he] investigated that information, located the witness (after fifteen years) and spoke to him that the exculpatory nature of the information came to the surface." Id.

We begin by noting it is unclear whether the PCRA court determined appellant's Brady claim pertaining to the "Maculla" note was untimely and, if so, on what basis. However, the court held an evidentiary hearing on this claim precisely to determine whether it was timely, after which it denied relief. N.T. 11/30/2015, 38; N.T. 7/14/2016, 61. In its final order dated February 14, 2017, the PCRA court indicated it had dismissed the petition as untimely. Later, in its Pa.R.A.P. 1925(a) opinion, the PCRA court again indicated the petition was untimely, see PCRA Ct. Opinion, 8/9/2017, slip op. at 5, but also noted the " Brady issues, if correct, would fall under 42 Pa.C.S. [§]9545(b)(1)(i) [ (governmental interference exception) ] and possibly [§]9545(b)(1)(ii) [ (newly-discovered fact exception) ]," Id. at 6. Appellant now contends that, "[t]o the extent the court found [his petition] untimely, the court erred." Appellant's Brief at 24. We disagree.

It is well-settled a Brady violation may fall within the governmental interference exception. Commonwealth v. Breakiron , 566 Pa. 323, 781 A.2d 94, 98 (2001). Nevertheless, "a petition invoking the exception must be filed within 60 days of the date the claim could have been filed pursuant to [S]ection 9545(b)(2)." Id. (citation omitted). The same is true of a petition invoking the newly-discovered fact exception. Commonwealth v. Bennett , 593 Pa. 382, 930 A.2d 1264, 1272 n.11 (2007).

Here, appellant raised a single claim in his initial petition: that the Commonwealth violated Brady , and thereby offended his due process rights, by failing to disclose favorable evidence that was material either to his guilt or punishment. See Appellant's Third PCRA Petition, 8/9/2012, 2-8, 10 ¶¶ 7-28, 34; see also 42 Pa.C.S. § 9543(a)(2)(i) (a petitioner may obtain post-conviction relief where he pleads and proves by a preponderance of the evidence that his conviction or sentence resulted from "[a] violation of the Constitution of this Commonwealth or the Constitution or laws of the United States which, in the circumstances of the particular case, so undermined the truth-determining process that no reliable adjudication of guilt or innocence could have taken place"). Accordingly, to be considered timely, whether under the governmental interference or newly-discovered fact exceptions, appellant's petition must have been filed within 60 days of the date his Brady claim could have been presented. 42 Pa.C.S. § 9545(b)(2).

We conclude appellant failed to meet this requirement. Although he filed his petition within 60 days of the date his investigator located and secured a favorable declaration from McCullough, his Brady claim was predicated on the Commonwealth's suppression of the "Maculla" note , not its failure to disclose the statement McCullough gave to the defense 15 years later. As it was the disclosure of the note that formed the basis of appellant's due process claim, Section 9545(b)(2)'s 60-day filing requirement was triggered on the date the Commonwealth produced the note to the defense: March 6, 2012. Because appellant did not raise his Brady claim until August 9, 2012, his petition was untimely.

In making this determination, we reject appellant's argument that "[n]o claim could have been raised" within 60 days of March 6, 2012, on the basis that the note, "without more, is not by itself exculpatory and would not give rise to a Brady claim." See Response in Opposition to the Commonwealth's Motion to Dismiss, 8/27/2014, 3. This assertion is directly contrary to appellant's prior claims in his petition. There, as previously discussed, appellant argued the note itself was material evidence that the Commonwealth was required to disclose pursuant to Brady , because it identified John "Maculla" as an eyewitness and, more pointedly, indicated he "got [the] tag #" of the car involved in the homicide. See Appellant's Third PCRA Petition, 8/9/2012, 6 ¶ 22. Appellant argued this evidence was material because it may have led to "evidence that a different car was involved in the shooting," which "he would have used [ ] to refu[t]e the inferences of identity and motive[.]"Id. at 7 ¶ 25. Appellant no longer espouses this theory, presumably because it defeats his assertion that the claim could not have been raised sooner.

Moreover, while we recognize McCullough's declaration certainly was evidence favorable to appellant, we reiterate it was merely additional proof supporting the merits of appellant's claim the Commonwealth violated his due process rights by withholding the note identifying McCullough as an eyewitness; it was not, however, the basis of the Brady claim itself. It was the disclosure of the "Maculla" note, rather than the discovery of the declaration, that informed the basis of appellant's Brady claim, and it was incumbent upon him to file his petition within 60 days of the date he received that material alerting him of that claim. Nothing prevented appellant from filing his Brady claim within 60 days of receiving the note, and Section 9545(b)(2) required that he do so. Consequently, we lack jurisdiction to consider the merits of this untimely Brady claim.

B. The Robinson Documents

1. Timeliness

Unlike his claim premised on the "Maculla" note, appellant's Brady claim regarding the evidence of another potential suspect was raised within 60 days of the Commonwealth's disclosure of that material. Pursuant to the federal court's July 9, 2014 order instructing the Commonwealth to grant appellant access to its file and the homicide detective's H-file, the Commonwealth made the files available to appellant on August 7, 2014. Within 60 days of that date, on October 6, 2014, appellant filed his supplemental petition raising the additional Brady claim. He has therefore satisfied 42 Pa.C.S. § 9545(b)(2) regarding this claim.

In addition, our review reveals appellant satisfied an exception to the PCRA's time-bar with respect to this claim, as the facts upon which his Brady claim were predicated — that the Commonwealth withheld evidence pertaining to another suspect — were unknown to him until the Commonwealth was forced to open its files on August 7, 2014. 42 Pa.C.S. § 9545(b)(1)(ii). Accordingly, we have jurisdiction to consider this claim, and we proceed to the arguments of the parties.

2. Arguments

Appellant claims the Commonwealth violated Brady by failing to disclose the statements indicating Robinson confessed to the murder, and also by suppressing certain police paperwork showing the police investigated those allegations against Robinson. See Appellant's Brief at 27-42. This evidence "of another person's culpability," appellant contends, "was favorable to the defense, yet the prosecution did not disclose any of it to the defense at trial." Id. at 36. Thus, appellant argues the first two prongs of the Brady test — the government suppressed evidence, and the evidence was favorable to the accused — "are easily met." Id.

Appellant also claims the suppressed evidence was material. He notes the withheld statements demonstrate Robinson "confessed to the killing to at least two different people[,]" Rutherford and Smith, each of whom "promptly reported the confessions to both the police and other people." Id. at 37. Appellant continues that Robinson had a motive to kill the victim because Robinson was selling drugs out of a house in the neighborhood where the victim was associated with Town Watch. Id. In this regard, appellant highlights the fact Robinson once referred to the victim as a "snitch," and notes several of the suppressed reports showed Robinson had access to guns and had previously threatened people with them. Id. Finally, appellant observes Rutherford, in his statement, indicated he had previously seen Robinson in a black Lincoln, "the same type of vehicle described by witnesses" as belonging to the shooter. Id. Appellant concludes this evidence "would have been more than sufficient to charge and convict" Robinson of the murder. Id.

In terms of proving materiality, appellant alleges this evidence satisfies the Brady standard because, if the Commonwealth had provided it prior to trial, it "would have allowed competent defense counsel to argue that [Robinson] was the real killer." Id. at 37-38. In appellant's view, "[e]vidence that another person confessed to the crime is unquestionably exculpatory and material." Id. at 27, citing Dennis v. Sec'y, Pa. Dep't of Corr. , 834 F.3d 263, 304-05, 311 (3d Cir. 2016) (en banc ) (suppressed evidence would have allowed defense counsel to argue another person committed the crime). Appellant further asserts "[c]ounsel would also have been able to challenge the adequacy of the police investigation," id. at 38, as "[p]olice reports that corroborate the details of that confession are likewise exculpatory." Id. at 27-28, citing Smith v. Sec'y of N.M. Dep't of Corr. , 50 F.3d 801, 830 (10th Cir. 1995) ("[W]hile the knowledge the police were investigating [another suspect] would arguably carry significant weight with the jury in and of itself, that fact would also have been useful in discrediting the caliber of the investigation or the decision to charge the defendant[.]") (quotation and citation omitted).

Finally, appellant argues the PCRA court applied an improper standard of materiality by focusing on whether the documents "would have made a difference" in the jury's verdict. Id. at 41, citing PCRA Ct. Opinion, 8/9/2017, slip op. at 8. According to appellant, the PCRA court's focus should have been on whether the Commonwealth's suppression of the evidence had "any adverse effect ... on the preparation or presentation of [appellant]'s case." Id. at 41, quoting Bagley , 473 U.S. at 683, 105 S.Ct. 3375. Under this standard, he argues, the suppressed evidence meets Brady 's materiality requirement because "[t]he entire course of the defense would have been changed" had it been disclosed. Id. at 42. In this respect, appellant notes there was "no evidence to suggest that anyone other than [appellant] had committed the offense" and, thus, "counsel chose to raise a self-defense case, based on Price's testimony that the deceased had drawn his weapon." Id. at 41-42. Appellant asserts that "[h]ad counsel been provided with the evidence of [Robinson]'s confession, he could have challenged the credibility of Price's testimony ... and argued that [Robinson] was the actual perpetrator." Id. at 42.

The Commonwealth responds that appellant's Brady claim "plainly fails on materiality grounds." Commonwealth's Brief at 31. Regarding the evidence concerning Robinson's confessions, the Commonwealth argues that, even if it had been disclosed, it would not have had a reasonable probability of affecting the verdict. It notes that not only did Robinson provide an alibi for the murder, but "Rutherford and his associates were the apparent sources of all of the multi-layered hearsay contained in the statements, which reflected obvious animus toward Robinson based on his collection of drug debts." Id. at 35. In the Commonwealth's view, it would not "surprise jurors that a drug dealer cultivating a violent image to aid such collection efforts had a business reason to falsely boast about being involved in a well-publicized local crime until being questioned by police."Id. The Commonwealth concludes: "Viewing the evidence in its entirety, the gossip circulating in early November 1997 among a group of people who did not witness the murder and had scores to settle with Robinson over his business practices would not satisfy Brady 's materiality requirement." Id. at 42.

Turning to appellant's claim the statements and police paperwork would have enabled him to challenge the adequacy of the police investigation, the Commonwealth highlights additional documents disclosed pursuant to the discovery order showing the police promptly investigated all tips relating to possible perpetrators during the early days of the investigation and quickly eliminated them as viable suspects. See Id. at 35-38. As the Commonwealth explains, any "[a]ttacks on the integrity of the police investigation would thus have prompted additional Commonwealth testimony outlining these efforts." Id. at 38. The Commonwealth notes as well that appellant's proposed use of the statements would have resulted in a renewed focus on the rapid accumulation of evidence indicating appellant's guilt, which police collected while simultaneously investigating the other early leads. See Id. at 38-41 (setting forth a chronology of the police investigation and detailing the evidence demonstrating appellant's identity as the shooter). The Commonwealth submits that, as the investigation evolved, "it became clear that the carjacker of Michael Havens and the shooter of Robert Campbell were the same person, that [appellant] was that lone perpetrator, that he shot the victim in front of three witnesses (Bryon Price, Martin Johnson, and Beth Johnson) while wearing Mr. Haven[s]'s distinctive lumberjack shirt, that — after being seen driving the stolen Lincoln by several people — he later tried to destroy it and the shirt by setting the vehicle on fire, and that he sold the murder/carjacking weapon to Keith Smith." Id. at 42.The Commonwealth next disputes appellant's position it would have been preferable for him to use the evidence to posit an "alternate perpetrator" defense, rather than the theory of self-defense he presented at trial. Id. at 42-43. The Commonwealth avers this "post hoc evaluation warrants skepticism" because it "ignores the central problem facing the defense: namely, that [appellant]'s presence at the scene of the murder and his participation in it was firmly established by testimonial and physical evidence." Id. at 43. In this vein, the Commonwealth reiterates appellant was identified as the shooter by one eyewitness who knew him (Bryon Price) and by two others (Martin and Beth Johnson) who identified him by means of the distinctive lumberjack shirt taken during the carjacking of Michael Havens, who also positively identified him. Id. Additionally, appellant was "later seen in possession of the distinctive gun used in both crimes before selling it in a highly inculpatory fashion and was repeatedly seen driving the stolen get-away car before it was set on fire." Id. In the context of this evidence, the Commonwealth concludes appellant's "suggestion that he had a reasonable probability of being acquitted if only defense counsel had advanced an alternative perpetrator defense unsupported by any testimony — whether instead of, or in addition to, his claim [of] self-defense — defies the record and common sense." Id. (footnote omitted).

In his reply brief, appellant repeats the general thrust of his argument that the suppressed evidence was material because it "would have not only allowed defense counsel to raise a reasonable doubt about [appellant]'s guilt but would have allowed him to dramatically shift strategy from a very weak self-defense theory to a much stronger defense that [Robinson], a drug dealer with a motive to kill, was the actual perpetrator." Appellant's Reply Brief at 5. In support, appellant relies on Dennis , supra , in which the United States Court of Appeals for the Third Circuit concluded evidence of a witness's prior inconsistent statement was material because the evidence " ‘would have enabled defense counsel to raise a defense he was otherwise unable to present — that [another person] committed the murder.’ " Id. at 6, quoting Dennis , 834 F.3d at 304-05. Appellant argues the same reasoning should apply here.

3. Analysis

We need not belabor our discussion of whether appellant has satisfied the first two components of Brady : without a doubt, the trove of statements and investigatory paperwork revealed during the federal discovery process were suppressed by the government and favorable to appellant. There is no dispute the Commonwealth failed to disclose these materials to the defense prior to trial, and some of them were plainly exculpatory on their face, as they identified an alternate suspect who allegedly claimed responsibility for the murder. Brady 's first two requirements are therefore clearly satisfied.

The question that remains is whether, even considering the improperly withheld material, appellant "received a fair trial, understood as a trial resulting in a verdict worthy of confidence." Kyles , 514 U.S. at 434, 115 S.Ct. 1555. Although we deem it to be a close call, after a careful review of the entire record, we agree with the PCRA court that the Commonwealth's evidence against appellant was so overwhelming there is no reasonable probability that if the Commonwealth had turned over the relevant evidence the result of the trial would have been different. See PCRA Ct. Opinion, 8/9/2017, slip op. at 8-9. In reaching this conclusion we begin, as we must, by considering the omitted evidence "in the context of the entire record[,]" for "[i]f there is no reasonable doubt about guilt whether or not the additional evidence is considered, there is no justification for a new trial." Agurs , 427 U.S. at 112-13, 96 S.Ct. 2392.

With this in mind, we highlight at the outset that, while appellant's Brady claim implicates his identity as Campbell's killer, the criminal episode resulting in Campbell's death began much earlier that day. At trial, the Commonwealth produced evidence that appellant, along with another unidentified individual, carjacked Michael Havens in the early morning hours of November 9, 1996. N.T. 11/5/1997, 146-54. During that encounter, appellant pointed a stainless steel revolver at Havens, forced him to surrender his wallet and keys, and ordered him into his own car — a dark blue Lincoln. Id. at 148-52. Havens sat in the back seat and appellant sat in the front passenger seat, facing and pointing his gun at Havens while appellant's accomplice drove. Id. at 150. Dissatisfied with the amount of money in Havens's wallet, appellant threatened to kill Havens if he did not produce more. Id. at 152. When Havens convinced appellant he had no additional money available in his bank account, appellant and his accomplice abandoned Havens on the side of a road and drove away in his car, which contained a distinctive lumberjack-style jacket inside. Id. at 152-53, 157-58.

Havens's identification of appellant as the assailant who carjacked him, pointed a gun at his face, and threatened to kill him before speeding off in his Lincoln was unwavering. He identified appellant from a photo array and at the preliminary hearing. Id. at 173, 193. When Havens identified appellant as his armed carjacker at trial, he explained he had no difficulty seeing appellant's face while being held hostage at gunpoint for fifteen to twenty minutes, as he was within one foot of him and the dome light was on inside the car as appellant counted his money. Id. at 153-54. As to Havens's confidence in his identification of appellant as the carjacker, he testified "there's no doubt in my mind. I know that he did it. I know that it's him." Id. at 174.

With regard to the murder, the Commonwealth presented two witnesses at trial, Martin and Beth Johnson, who were leaving their home across from the brightly-lit gas station when they heard a gunshot. N.T. 11/6/1997, 76-78, 94. At that moment they observed Campbell fall backward with his hands raised in the air. Id. at 78, 94. The Johnsons then saw the shooter, who was wearing a lumberjack-style jacket, flee into the driver's side of a dark Lincoln and speed off. Id. at 78, 82, 85, 94-95.

Byron Price testified appellant picked him up around 7:00 p.m. the evening of the murder in a blue Lincoln he had never before seen appellant drive. N.T. 11/6/1997, 6-7, 12. Appellant then drove them to the gas station and exited the car, but instructed Price to wait in the passenger seat. Id. at 9. Price testified to hearing a gunshot, then seeing appellant run back to the car with a chrome revolver in his hand. Id. at 9-10, 13. At that time Price observed Campbell lying on the ground next to a gas pump. Id. at 13. When appellant swiftly made a U-turn out of the gas station and sped away, Price asked him why he shot the man. Id. at 14-15. Appellant replied: "He drew on me." Id. at 15.

The Commonwealth also presented testimony that appellant admitted killing Campbell to his friends the next day. While seated in the stolen Lincoln and talking to a group of approximately fifteen people, appellant announced, "You know I got that body, the town watch man." Id. at 181-82. Still driving around in the Lincoln, appellant later encountered his friend Robert Golatt. Id. at 163. Appellant told Golatt "that he was at the service station and some, you know, the guy drawed [sic ] on him and he, you know, popped him first." Id. at 165. Appellant admitted he had used a chrome .357 handgun — a caliber consistent with the fatal gunshot wound to the victim's head. Id. ; N.T. 11/5/1997, 232. As a result of appellant's bragging, it became common knowledge "on the street" he had murdered Campbell. N.T. 11/6/1996, 164.

There was also evidence presented at trial that, about a week or two after the murder, appellant sold his chrome .357 revolver to Keith Smith. Id. at 107-18; N.T. 11/7/1997, 42-43. Smith subsequently turned the gun over to his lawyer, who immediately relinquished it to police. N.T. 11/7/1997, 14-17. Havens identified the gun at trial as identical to the one appellant had used in the carjacking, while Price identified it as similar in appearance to the one appellant used to kill Campbell. N.T. 11/5/1997, 170; N.T. 11/6/1997, 13, 115-16.

Price's girlfriend testified against appellant as well. She explained that she called a Crime Stoppers Tip Line prior to December 25, 1996, and identified appellant as Campbell's killer. N.T. 11/6/1997, 153-54. Appellant subsequently called her, admitted to killing the victim, and boasted there was no evidence against him. Id. at 154-56.

Finally, the Commonwealth presented evidence that appellant evaded police after they secured a warrant for his arrest. When police eventually located appellant he fled and, once captured, gave the officers a false name, inaccurate address, and multiple dates of birth. N.T. 11/7/1997, 57-88, 100-08, 118-20.

Against the backdrop of this extensive evidence of appellant's guilt, we now consider the material revealed in 2014 in response to the federal court's order. Although appellant emphasizes numerous statements and investigatory documents that were withheld by the Commonwealth, they largely derive from a single event: the dispute over Robinson's collection of drug debts from individuals associated with the house located at 929 Wynnewood Road. After Robinson repeatedly threatened Rutherford for failing to pay a drug debt owed to him, Rutherford and Smith came forward to report Robinson had confessed his supposed involvement in the murder. The vast majority of the remaining withheld statements and investigatory reports merely document the dispute between Rutherford and Robinson or regurgitate Rutherford's and Smith's claims Robinson confessed to being the killer. Two notable exceptions include Rutherford's vague description he had, at some unknown point in the past, seen Robinson in a Lincoln, and Durham's assertion she was at a pay phone near the gas station around the time of the murder and saw what appeared to be Robinson drive by in his gray vehicle, which was either a Lexus or an Acura.

Upon careful examination of the withheld material in the context of the entire record, we cannot say the favorable evidence could reasonably be taken to put the whole case in such a different light as to undermine confidence in the verdict. Kyles , 514 U.S. at 434-35, 115 S.Ct. 1555. While we do not discount the exculpatory power a third-party's confession — even one reported through yet another party — may have in an ordinary case, in the context of the other evidence presented at this particular trial, the withheld evidence regarding Robinson is "too little, too weak, or too distant from the main evidentiary points to meet Brady 's standards." Turner v. United States , ––– U.S. ––––, 137 S.Ct. 1885, 1894, 198 L.Ed.2d 443 (2017).

In reaching this conclusion, we "bear in mind that not every item of the State's case would have been directly undercut if the Brady evidence had been disclosed." Kyles , 514 U.S. at 451, 115 S.Ct. 1555. Mindful of that instruction, we agree with the Commonwealth that appellant "ignores the central problem facing the defense: namely, that [appellant]'s presence at the scene of the murder was firmly established by testimonial and physical evidence." Commonwealth's Brief at 43. Indeed, our careful review leads us to the inescapable conclusion that, whatever evidentiary value the material regarding Robinson may have in its own right, it does nothing to weaken the main evidentiary points raised at trial. Cf. Kyles , 514 U.S. at 451, 115 S.Ct. 1555 (evidence was material where "the physical evidence remaining unscathed [by the withheld evidence] would ... hardly have amounted to overwhelming proof that [the defendant] was the murderer"). Critically, the withheld material in no way calls into question any of the evidence proving appellant was the culprit who carjacked Havens. And the unchallenged evidence from that crime — the hijacked Lincoln, appellant's chrome .357 revolver, and the stolen lumberjack jacket — directly connected appellant to Campbell's shooting only hours later. Perhaps even more damning, yet also unaffected by the withheld material, was Price's eyewitness testimony that appellant killed Campbell and then explained to Price he did so because Campbell allegedly "drew on him." There was also, of course, the evidence that appellant sold his chrome revolver shortly after the murder; bragged to a large group of people he was the killer while sitting in Havens's stolen Lincoln; told Price's girlfriend he killed Campbell and boasted there was no evidence against him; and evaded police for months and gave false information regarding his identity when he was finally apprehended. None of this evidence admitted at trial is cast into doubt or undercut by the withheld material.

Given this overwhelming and intact evidence of appellant's guilt, we are not persuaded by his argument he would have had "a much stronger defense" had he been able to present an alternate perpetrator theory, rather than the theory of self-defense he presented at trial. Appellant's Reply Brief at 5. In this respect, we reject appellant's reliance on the Third Circuit's sharply-divided en banc decision in Dennis . See Id. at 6-8; see also Appellant's Brief at 27. It is true the majority in Dennis held, under the facts of that case, there was a reasonable probability that had the jury heard an "other person" defense based on the withheld material, the result of the proceeding would have been different. Dennis , 834 F.3d at 311. As the Third Circuit explained, however, "the documents not only support an alternative shooter theory, but the very same alternative shooter theory that defense counsel could have been prepared to raise had [additional withheld evidence] also been disclosed." Id. (emphasis in original). That other withheld evidence included "a receipt corroborating Dennis's alibi, an inconsistent statement by the Commonwealth's key eyewitness, and [additional] documents indicating that another individual committed the murder[,]" the cumulative effect of which "effectively gutted the Commonwealth's case against Dennis." Id. at 269 ; see also Id. at 313 ("The withholding of the Brady material would have given defense counsel unique ability to discredit the Commonwealth's primary witnesses, bolster his alibi defense using objective documentary support from a disinterested party, highlight the shoddiness of the Commonwealth's investigation, and perhaps point to another perpetrator."). The facts of Dennis , as well as the nature and extent of the withheld evidence involved in that case, are far different from those presented here. And contrary to the Third Circuit's conclusion in Dennis that the suppressed evidence there "effectively gutted" the Commonwealth's case, as we have explained, the same cannot be said of the withheld evidence here. We also reject appellant's suggestion, see Appellant's Brief at 37-38, that any withheld evidence that could arguably be used by the accused to present a previously unavailable defense theory, or which might cast doubt upon the integrity of the police investigation, automatically renders it "material" in the constitutional sense. See Commonwealth v. Chambers , 570 Pa. 3, 807 A.2d 872, 887 (2002) ("The mere possibility that an item of undisclosed information might have helped the defense, or might have affected the outcome of the trial, does not establish materiality in the constitutional sense.") (citation omitted). Instead, as we have emphasized above, the law is clear that evidence is material "only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A reasonable probability is a probability sufficient to undermine confidence in the outcome." Id. at 887-88, citing Bagley , 473 U.S. at 682, 105 S.Ct. 3375.

On this point, we find the United States Supreme Court's recent decision in Turner , supra , particularly instructive. Turner involved the brutal rape and murder of Catherine Fuller, in what the government believed had been a group attack. 137 S.Ct. at 1889. The withheld evidence in Turner included the identities of two men, James McMillan and Gerald Merkerson, whom a witness had seen run into the alley where Fuller was murdered and stop near the garage where she had allegedly been raped. Id. at 1891. The defendants argued this information was material because after Fuller's murder, McMillan assaulted and robbed two other women of comparable age in the same neighborhood, and the suppressed information could have suggested McMillan was returning to the scene of the crime to cover his tracks. Id. at 1894. More precisely, the defendants argued that with the withheld evidence "they could have raised an alternative theory, namely, that a single perpetrator (or two at most) had attacked Fuller." Id. at 1893. The defendants further argued they could have used the withheld evidence "to suggest that an incomplete investigation had ended up accusing the wrong persons." Id. at 1894. The Supreme Court found these arguments unpersuasive, relying on the testimony of multiple other government witnesses who affirmed that Fuller had been killed in a group attack, and reasoning that, given the strength of the evidence presented to the jury, the withheld evidence did not undermine confidence in the verdict. Id.

The analysis and result in Turner , while admittedly bound to the unique facts of that case, supports our conclusion the withheld evidence in this case was not material. Contrary to appellant's claim, it is not enough, for purposes of establishing materiality under Brady , to simply allege that the withheld evidence may have opened the door to an otherwise unavailable defense theory, or to challenge the completeness of the police investigation. Rather, the linchpin of materiality is whether there exists a reasonable probability that, had the evidence been disclosed, the result of the proceeding would have been different. Id. at 1893. As we conclude the withheld evidence in this case does not undermine confidence in the jury's verdict, and there is not a reasonable probability the result of appellant's trial would have been different had it been disclosed, appellant's Brady claim does not entitle him to relief. C. Cumulative Effect of Suppressed Evidence

Before this Court, appellant raises an additional claim that he was prejudiced by the cumulative effect of the Commonwealth's alleged Brady violations. See Appellant's Brief at 42-43, citing Kyles , 514 U.S. at 436, 115 S.Ct. 1555 (cumulative effect of state's failure to reveal multiple pieces of exculpatory evidence undermined fairness of trial and entitled defendant to relief). The Commonwealth responds this claim is waived because it was neither preserved before the PCRA court nor included in appellant's Pa.R.A.P. 1925(b) statement of matters complained of on appeal. See Commonwealth's Brief at 45-46.

We disagree with the Commonwealth that appellant has waived this claim. True as it is that appellant failed to raise cumulative prejudice as a standalone claim in the court below and in his Rule 1925(b) statement, we agree with appellant that "[a]s a matter of law, a [c]ourt reviewing multiple pieces of exculpatory evidence that the prosecution failed to disclose is required to view the effect of the non-disclosures cumulatively." Appellant's Reply Brief at 11. Indeed, the Supreme Court in Kyles instructed that materiality of withheld evidence must be "considered collectively, not item by item." 514 U.S. at 436, 115 S.Ct. 1555. See also Wearry v. Cain , ––– U.S. ––––, 136 S.Ct. 1002, 1007, 194 L.Ed.2d 78 (2016) (per curiam ) ("[T]he state postconviction court improperly evaluated the materiality of each piece of evidence in isolation rather than cumulatively[.]"). Thus, we agree with appellant "[t]his is not a waivable claim; it is, rather, the very nature of how a Brady claim is required to be reviewed." Appellant's Reply Brief at 11.

On the other hand, we also recognize the precise nature of the claim appellant urges us to consider is the cumulative prejudice created by the Commonwealth's suppression of the "Maculla" note along with the Robinson documents. See Appellant's Brief at 42. Given our determination that appellant's Brady claim concerning the "Maculla" note is untimely, that evidence is not properly before us, and we therefore decline to consider it in the analysis. We underscore, however, that in addressing appellant's sole timely-raised Brady claim concerning the various withheld materials respecting Robinson, we have carefully considered and rejected appellant's cumulative materiality argument, as set forth at length above.

D. PCRA Court's Evidentiary Ruling

Appellant argues the PCRA court abused its discretion when it ruled he was not entitled to materials contained in the files maintained by the Pennsylvania Department of Probation and Parole and the Philadelphia Department of Probation and Parole relating to John McCullough III, the son of John McCullough. See Appellant's Brief at 44-49. Appellant stresses that his request "was not a discovery request subject to Pa.R.Crim.P. 902(E)(1)" because he was "not seeking to obtain the information from the prosecutor or its agents[.]" Id. at 45. Even if construed as a discovery request, appellant continues, his request satisfied the "exceptional circumstances" requirement of Rule 902(E)(1), as the requested files may have provided him with information he could have used to challenge the witness's motive for testifying, as well as his "drug use and mental health condition." Id. at 46-48.

The Commonwealth argues appellant's evidentiary claim is partially waived and meritless in any event. See Commonwealth's Brief at 52-56. As to waiver, the Commonwealth notes appellant did not object or ask the PCRA court to set forth its reasoning when it denied appellant's request for the files following its in camera review and, thus, "he cannot complain now that the lack thereof somehow supports his challenge[.]" Id. at 53. On the merits, the Commonwealth relies on the strict standard for obtaining discovery pursuant to Rule 902(E)(1) and argues the PCRA court acted well within its discretion when it denied appellant's request because the "fact of any probation or parole, including any violations thereof, was already publicly available information" and, therefore, appellant's request "exceeded what would have been reasonable for purposes of establishing possible bias." Id. at 54. Moreover, the Commonwealth contends the PCRA court acted appropriately when it denied appellant "the opportunity to turn the limited PCRA discovery mechanisms into an invasion of the witness's mental health and other personal information[,]" much of which appellant successfully elicited through cross-examination in any event. Id. at 55-56. The Commonwealth concludes the PCRA court's decision to hold an in camera review "struck an appropriate balance, ensuring that any material relevant to impeachment of John McCullough III was produced while guarding against needless intrusions on the witness's privacy." Id. at 56.

Initially, we reject appellant's attempt to recast his request for the witness's records as anything other than a discovery request governed by Rule 902. As the Commonwealth points out, appellant offers no support for his proposed limitation on the definition of "discovery" in the PCRA context to materials obtained directly from the police or district attorney's office, as opposed to those in the custody of other Commonwealth agencies or even non-governmental entities. See Commonwealth's Brief at 55 n.24. And, in fact, this Court has previously construed medical records, which are maintained by entities completely divorced from the Commonwealth, pursuant to the discovery provisions of Rule 902(E). See, e.g. , Commonwealth v. Keaton , 615 Pa. 675, 45 A.3d 1050, 1094 (2012) (upholding PCRA court's denial of discovery motion that "essentially requested wholesale discovery of police and medical records ") (emphasis added). Accordingly, we conclude appellant's claim is properly reviewed under the standards for obtaining discovery pursuant to Rule 902(E)(1).

Viewed under these standards, we conclude the PCRA court did not abuse its discretion in denying appellant's request for the witness's probation and parole files. See Commonwealth v. Bryant , 579 Pa. 119, 855 A.2d 726, 749-50 (2004) ("We review the denial of a discovery request in post-conviction proceedings for an abuse of discretion."). Appellant's discovery request was overly broad, and much of the impeachment material he hoped to find was publicly available or could have been obtained by less obtrusive means. Under these circumstances, the PCRA court did not abuse its discretion by holding an in camera review and otherwise denying appellant's overly-broad discovery request. See generally Commonwealth v. Sattazahn , 597 Pa. 648, 952 A.2d 640, 662 (2008) (under less stringent "good cause" standard governing discovery for first PCRA petitions in capital cases, a petitioner must make "more than just a generic demand for potentially exculpatory evidence that might be discovered if the petitioner is permitted to review requested materials"); Commonwealth v. Collins , 598 Pa. 397, 957 A.2d 237, 271-72 (2008) (rejecting "sweeping requests" for PCRA discovery under "good cause" standard); Commonwealth v. Williams , 557 Pa. 207, 732 A.2d 1167, 1175 (1999) (petitioner "failed to establish any specific ground that would warrant his broad-based discovery request").

IV. Constitutionality of 42 Pa.C.S. § 9711(d)(9)

In his final claim, appellant argues that because the language of 42 Pa.C.S. § 9711(d)(9) (significant history of violent felony convictions aggravator) is "materially indistinguishable" from the residual language of the federal Armed Career Criminal Act (ACCA), 18 U.S.C. § 924(e)(2)(B)(ii) — which was ruled unconstitutional by the United States Supreme Court in Johnson and made retroactive by Welch — his death sentence violates the Eighth and Fourteenth Amendments to the United States Constitution. Appellant's Brief at 43. Appellant recognizes this claim is untimely under this Court's recent decision in Commonwealth v. Spotz , 642 Pa. 717, 171 A.3d 675, 681-82 (2017) (explaining "the (d)(9) aggravator must have been held unconstitutional at the time" the petition is filed), but asserts he raises the issue solely "to preserve it for federal review." Appellant's Brief at 44. As appellant correctly concedes, Spotz precludes our exercise of jurisdiction over his present challenge to the constitutionality of the Section 9711(d)(9) aggravator, and we therefore need not need discuss it further.

V. Conclusion

Having concluded that appellant's claims in his third PCRA petition and the multiple supplements thereto are either time-barred or lack merit, we affirm the order of the PCRA court dismissing appellant's serial petition.

Chief Justice Saylor and Justices Baer, Todd and Mundy join the opinion.

Justice Wecht files a dissenting opinion in which Justice Donohue joins.

JUSTICE WECHT, dissenting

Ricardo Natividad, a capital litigant, appeals from an order dismissing his third petition filed under the Post Conviction Relief Act ("PCRA"), 42 Pa.C.S. §§ 9541 - 9546. Today's learned Majority affirms the PCRA court's order, denying relief on all five issues that Natividad raises. I agree with the Majority's thoughtful disposition of three of these issues: that Natividad's claim based upon the "Maculla" note was untimely; that this Court is precluded from exercising jurisdiction over Natividad's challenge to the constitutionality of 42 Pa.C.S. § 9711(d)(9) ; and that the PCRA court properly exercised its discretion in denying Natividad's discovery request.

However, because the Commonwealth violated Brady v. Maryland , 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), when it withheld evidence from multiple sources that Rupert Robinson confessed to the murder for which Natividad was convicted and sentenced to death (hereinafter "the Robinson documents"), I respectfully dissent. While it is not unreasonable for the Majority to characterize the materiality of the Robinson documents as a "close call," my evaluation of both the record and the principles upon which Brady and its progeny are based leads me to conclude that this undisclosed evidence was material to Natividad's case. In light of this conclusion, and the concomitant requirement of a new trial, I would not reach Natividad's final issue, in which he asserts prejudice occasioned by the cumulative effect of the Commonwealth's Brady violations.

On November 10, 1997, Natividad was convicted of, inter alia , first-degree murder for the November 9, 1996 carjacking of Michael Havens and the subsequent fatal shooting of Robert Campbell. Natividad was sentenced to death. On direct appeal, by way of a plurality opinion, this Court affirmed Natividad's judgment of sentence. Commonwealth v. Natividad , 565 Pa. 348, 773 A.2d 167 (2001) (Opinion Announcing Judgment of the Court). Over the course of the next ten years, Natividad filed two PCRA petitions, both of which were denied. Natividad then filed a petition for writ of habeas corpus in federal court. In that proceeding, Natividad sought and received discovery from the Commonwealth, which yielded previously undisclosed exculpatory evidence. On August 9, 2012, Natividad filed the instant PCRA petition, and subsequently sought leave to amend that petition after additional production of discovery revealed the previously undisclosed Robinson documents.

Because the Majority faithfully and comprehensively summarizes the Robinson documents, there is no need for me fully to reproduce their contents here. See Majority Opinion at 19–23 (citing Natividad's Supplement to Third PCRA Petition, 10/6/2014). Nevertheless, some particularly compelling portions bear repetition. On November 14, 1996, Joseph Rutherford provided a statement to police detailing an interaction with Robinson that occurred on November 11, 1996. According to Rutherford, while arguing over a drug debt, Robinson threatened to kill Rutherford and stated that "he would do me like he did Bob down at the gas station." Natividad's Supplement to Third PCRA petition, 10/6/2014, Exh. 1 at 4. On November 13, 1996, prior to giving his official statement to the police, Rutherford told Officer Rita Wilson, while she was responding to an altercation at a bar, that Robinson said to him, "we're going to do to you what we did to the guy at 63rd and Vine." Id. , Exh. 8 at 2.

On November 14, 1996, Cynthia Smith also gave a statement to police. Smith stated that Robinson alerted her to the Campbell murder shortly after it occurred. She stated that Robinson came to her house, turned on the news, and asked, "Didn't you hear about the guy getting shot — down at the gas station. You know the guy — the fucking snitch — that town watch guy Bobby Campbell." Id. , Exh. 2 at 2. On November 13, 1996, Smith asked Robinson if he was involved in the shooting, to which Robinson responded, "Yeah, I did it," and further stated, "That's what happens to snitches." Id. at 3-4. Robinson placed himself at the gas station shortly after the shooting and stated that he saw Campbell on the ground bleeding and that he observed a gun in a holster on Campbell's waist. Id. , Exh. 3 at 2-3.

In his amended petition at issue herein, Natividad argued that Rutherford's and Smith's statements and the police investigatory files indicated that "another person ... confessed he committed the crime for which [Natividad] has been convicted and sentenced to death." Id. at 3. Natividad claimed that, in violation of Brady , the "Commonwealth withheld evidence of another highly investigated suspect," who was also the "confessed killer of the victim." Id. at 5. Natividad contended that "there is a reasonable probability of a different outcome in this trial if the Commonwealth had timely produced the evidence that [Robinson] confessed to shooting and killing the victim." Id. at 12. The PCRA court denied relief.

In order to establish a Brady violation, a defendant must show that: (1) evidence was suppressed by the state, either willfully or inadvertently; (2) the evidence was favorable to the defendant, either because it was exculpatory or because it could have been used for impeachment; and (3) the evidence was material, in that its omission resulted in prejudice to the defendant. Strickler v. Greene , 527 U.S. 263, 281-82, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999). Evidence is material "only if there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different. A ‘reasonable probability’ is a probability sufficient to undermine confidence in the outcome." United States v. Bagley , 473 U.S. 667, 682, 105 S.Ct. 3375, 87 L.Ed.2d 481 (1985). Critically, in analyzing whether there is a reasonable probability that the result would have been different, "[t]he question is not whether the defendant would more likely than not have received a different verdict with the evidence, but whether in its absence he received a fair trial, understood as a trial resulting in a verdict worthy of confidence." Kyles v. Whitley , 514 U.S. 419, 434, 115 S.Ct. 1555, 131 L.Ed.2d 490 (1995).

Moreover, and of crucial import herein, this Court has recognized that Brady 's materiality assessment extends to consideration of "the defendant's ability to investigate alternate defense theories and to formulate trial strategy." Commonwealth v. Ly , 602 Pa. 268, 980 A.2d 61, 76 (2009). See also Commonwealth v. Green , 536 Pa. 599, 640 A.2d 1242, 1245 (1994) (holding that courts may "consider any adverse effect that the prosecutor's failure to disclose might have had on not only the presentation of the defense at trial, but the preparation of the defense as well"). In Commonwealth v. Willis, 616 Pa. 48, 46 A.3d 648 (2012) (Opinion Announcing the Judgment of the Court), we reinforced this concept:

[N]ondisclosed favorable evidence which is not admissible at trial may nonetheless be considered material for Brady purposes where the Commonwealth's failure to disclose such evidence adversely affected the presentation of the defense at trial, or the defense's preparation for trial, such that there is a reasonable probability that, had the evidence been disclosed to the defense, the result of the proceeding would have been different.

Id. at 670.

The Commonwealth argues that the leads and information contained in the Robinson documents amount merely to a "collection of recycled gossip that surfaced during the first week after the murder," and therefore are not material. Brief for Commonwealth at 33. The Majority appears to agree, concluding that the Robinson documents "largely derive from a single event: the dispute over Robinson's collection of drug debts," and that most of the withheld material either "merely document[s] the dispute between Rutherford and Robinson or regurgitate[s] Rutherford's and Smith's claims [that] Robinson confessed to being the killer." Majority Opinion at 34.

I do not dispute that, to some extent, the withheld materials include the same information echoing off of, or repeated by, multiple sources. Nonetheless, it is erroneous to overlook or minimize the significance of the fact that a third party, Robinson, confessed to two different people, on separate occasions, to being the perpetrator of the crime for which Natividad ultimately was charged and convicted. I cannot agree that such evidence is, as the majority concludes, " ‘too weak, or too distant from the main evidentiary points to meet Brady 's standards.’ " Id. at 35 (quoting Turner v. United States , ––– U.S. ––––, 137 S.Ct. 1885, 1894, 198 L.Ed.2d 443 (2017) ). To the contrary, I view this evidence as compelling, inasmuch as it strikes right at the heart of this case.

As noted, and as must be emphasized, Natividad is not required to prove that, had the suppressed material been disclosed, he would have prevailed at trial. To establish Brady materiality, a defendant is not required to shoulder such a surpassingly formidable burden. The defendant must prove only that, due to the Commonwealth's suppression of evidence, he was denied a fair trial, understood as a trial resulting in a verdict not worthy of confidence. See Kyles , 514 U.S. at 434, 115 S.Ct. 1555. In my view, Natividad has done so.

Although it recites the proper standards as a general matter, the Majority appears ultimately not to apply those standards here. Instead, the Majority engages in something more closely resembling a sufficiency analysis. After a thorough summary of both the evidence presented by the Commonwealth inculpating Natividad and the content of the withheld Robinson materials, the Majority concludes that the "Commonwealth's evidence against [Natividad] was so overwhelming there is no reasonable probability that if the Commonwealth had turned over the relevant evidence the result of the trial would have been different." Majority Opinion at 33 (citing PCRA Ct. Op., 8/9/2017, at 8-9). The Majority thus implies incorrectly that, for Brady purposes, Natividad was required to demonstrate that, as Kyles phrased it, "after discounting the inculpatory evidence in light of the undisclosed evidence, there would not have been enough left to convict." Kyles , 514 U.S. at 434-45, 115 S.Ct. 1555 (rejecting this argument, and reminding that Brady "is not a sufficiency of the evidence test"). See id. at 445 n.8, 115 S.Ct. 1555 (refuting the suggestion that "[the defendant] must lose because there would still have been adequate evidence to convict even if the favorable evidence had been disclosed"). Moreover, the Majority appears to discount the exculpatory statements of Rutherford and Smith, emphasizing that Rutherford and Smith offered their statements to police after Robinson repeatedly threatened Rutherford. See id. at 34. Credibility considerations fall outside the purview of an appellate court. Questions of credibility, bias, or motive to testify are assigned to the factfinder. See Dennis v. Sec'y, Pa. Dep't of Corr. , 834 F.3d 263, 301 (3d Cir. 2016) ("The jury makes the credibility determination, not the Court sixteen years post-trial.").

Perhaps most troubling is the Majority's speculation as to the effect that the withheld evidence would have had on the case as it was presented twenty-one years ago. The Majority fails to give adequate attention to Natividad's argument that his defense strategy would have been altered significantly had he been armed with the suppressed exculpatory evidence. Natividad maintains that the "entire course of the defense would have been changed" had the Commonwealth disclosed the evidence of Robinson's confession. Brief for Natividad at 42. Natividad notes that:

[a]lthough there was no forensic evidence connecting [Natividad] to the crime, and [Natividad] had never made any inculpatory statement to the police, counsel had no evidence to suggest that anyone other than [ ] Natividad had committed the offense. Thus, counsel chose to raise a self-defense case, based on Price's testimony that the deceased had drawn his weapon. This defense was necessarily weak as the deceased was found with his weapon holstered and snapped shut.

Id. at 41-42. After reviewing the entire record carefully, I agree.

Not only is there a reasonable probability that the result of the proceeding would have been different — the proceeding itself would likely have been much different. Quite simply, an entirely different defense strategy, naming Robinson as the perpetrator, would have been available to Natividad, a strategy that had a much better chance of success than the facially weak self-defense claim. It is worth reiterating that Natividad is not required to prove that he would have been acquitted had he advanced an alternative perpetrator theory based upon the suppressed evidence. Rather, Natividad need demonstrate only that, deprived of that evidence, he did not receive a fair trial, "understood as a trial resulting in a verdict worthy of confidence." Kyles , 514 U.S. at 434, 115 S.Ct. 1555. The Commonwealth's suppression of evidence that Robinson confessed to the Campbell murder (a confession made to two different people, on separate occasions) deprived Natividad of the opportunity to advance a defense theory more credible and viable than the one he pursued at trial.

In its entirety, Natividad's case in chief consisted of one witness, whose testimony spans only eight pages of transcript. See N.T., 11/10/1997, at 9-16. Seeking to undercut the reliability of Michael Havens' description of the man who carjacked him, trial counsel presented Officer Brian James, who testified about Havens' initial statement given to police following the robbery and carjacking. Officer James testified that Havens did not indicate that the carjacker was wearing a jacket. In a later, more detailed, statement, Havens described the man sitting in the passenger seat pointing a gun at him as wearing a long, black leather jacket. Related to the Campbell murder, Natividad offered no evidence in his own case in chief in support of any defense theory; self-defense, alternative shooter, or otherwise.

Overall, it is somewhat unclear what Natividad's defense strategy actually was. In his opening, trial counsel maintained that Natividad was not involved in the carjacking or murder. See N.T., 11/5/1997, at 144. Nevertheless, in response to Price's testimony, trial counsel sought, and received, a jury instruction on self-defense. Curiously, however, trial counsel attempted to discredit Price on cross-examination. Trial counsel questioned Price's lack of knowledge that Natividad was carrying a gun on the night of the murder and challenged Price's recollection of which gas pump Natividad had pulled alongside at the gas station. N.T., 11/6/1997, at 24-25, 30, 34-35. Trial counsel also questioned Price's initial failure to admit his involvement to police, even when officers warned him that he was a suspect. Id. at 39-47. Finally, on cross-examination, Price testified that he told police that Natividad was carrying a .38 Special revolver, but also admitted that his description did not include the distinctive black grips that adorned the .357 Magnum recovered from Keith Smith's lawyer. Id. at 66-67.

In his closing statement, defense counsel reiterated the inconsistencies in Price's testimony and implied that Price had a motive to inculpate Natividad in order to minimize his own involvement. N.T., 11/10/1996, at 34-38. Trial counsel additionally concluded in his summation that the Commonwealth failed to prove beyond a reasonable doubt that Natividad was the perpetrator of either the carjacking or the murder, arguing that the Commonwealth's case was based upon speculation and gossip on the street. Id. at 40-42.

In his closing, trial counsel never mentioned self-defense, presumably because such a theory was significantly undercut by the testimony that Campbell's gun was found snapped into its holster, clearly not drawn during the altercation. Arguably, these inconsistent approaches throughout trial could have been more damaging to Natividad's case than presentation of a coherent, albeit weak, theory of self-defense. It is, of course, never the defense's burden to convince the jury of a defendant's innocence. Nonetheless, the absence of a coherent defense strategy or any meaningful proffer of evidence favorable to the defense serves to highlight the barren evidentiary landscape upon which trial counsel apparently felt compelled to base his case.

This observation serves as well as the backdrop for comparing the case actually presented to the case the defense could have developed had it been equipped with the evidence suppressed by the Commonwealth. By suppressing the Robinson documents, the Commonwealth became the "architect" of Natividad's trial, usurping the defense's right to present the defense theory of its own choice, hamstringing the defense by limiting its strategy to an attempted discrediting of Commonwealth witnesses and a half-hearted endorsement of a feeble self-defense theory. See Brady , 373 U.S. at 87-88, 83 S.Ct. 1194 ("A prosecution that withholds evidence on demand of an accused which, if made available, would tend to exculpate him or reduce the penalty helps shape a trial that bears heavily on the defendant. That casts the prosecutor in the role of an architect of a proceeding that does not comport with standards of justice[.]"); Commonwealth v. Chamberlain , 612 Pa. 107, 30 A.3d 381, 402 (2011) (quoting California v. Trombetta , 467 U.S. 479, 485, 104 S.Ct. 2528, 81 L.Ed.2d 413 (1984) ) ("[The] Due Process Clause of the Fourteenth Amendment requires defendants be provided access to certain kinds of evidence prior to trial, so they may be ‘afforded a meaningful opportunity to present a complete defense.’ ").

Armed with the suppressed Robinson documents, Natividad could have advanced a third party guilt theory, shifting the entire course of his trial defense. Instead, Natividad's trial counsel was forced to pursue contradictory theories, espousing Natividad's innocence and simultaneously advancing, albeit somewhat fitfully, a theory of self-defense. In precluding the trier of fact from hearing Robinson's confessions, the Commonwealth significantly impeded Natividad's preparation and presentation of his defense, denying Natividad "a trial resulting in a verdict worthy of confidence." Kyles, 514 U.S. at 434, 115 S.Ct. 1555. See also Bagley , 473 U.S. at 693, 105 S.Ct. 3375 (Marshall, J., dissenting) ("The private whys and wherefores of jury deliberations pose an impenetrable barrier to our ability to know just which piece of information might make, or might have made, a difference.").

The Commonwealth asserts that Natividad's "post hoc evaluation" that an alternative perpetrator defense would have been preferable to a theory of self-defense "warrants skepticism." Brief for Commonwealth at 42-43. The Majority also concludes that "it is not enough, for purposes of establishing materiality under Brady , to simply allege that the withheld evidence may have opened the door to an otherwise unavailable defense theory." Majority Opinion at 37. That is an unfortunate oversimplification of what Natividad is doing. Natividad points to multiple pieces of specific evidence, suppressed by the Commonwealth, which implicate a third party in the crime for which Natividad was charged and convicted. This is evidence which, in the hands of competent defense counsel, would have dramatically shifted the course of Natividad's defense. This is more than merely the identification of a possible theory. It is instead the exposure of a meaningful, substantial defense that would have given Natividad a much greater chance of success. The Commonwealth obscures the fact that, as a direct result of the Commonwealth's suppression, Natividad now is consigned to the position of having to speculate.

It is largely the responsibility of prosecutors to make the initial pre-trial determination of the materiality of exculpatory evidence. If we permit prosecutors to speculate prospectively about the effect that nondisclosed favorable evidence may have on a future jury — or judge for themselves the credibility of such evidence behind closed doors — we cannot at the same time limit the defense's ability to speculate retrospectively about how that same evidence, suppressed by the Commonwealth, may have affected the jury deliberations. The inequities are patent: we deny relief to, or scold, the defense for speculating in circumstances where it was the Commonwealth's affirmative decision to suppress evidence that now precipitates the necessity for such speculation. This whipsaw approach encourages the prosecution to withhold evidence that may support a potential defense theory in the hope that the defense will not raise that theory at trial. If the evidence subsequently comes to light, the Commonwealth then simply can maintain that the evidence is not material under Brady because the defendant now is merely speculating as to the effect that undisclosed evidence would have had on trial counsel's preparation or presentation of the case. Perhaps I am misguided in feeling that such a peculiar state of affairs is evocative of Alice in Wonderland ; regardless, it certainly undermines the entire foundation of Brady .

Justice Thurgood Marshall, joined by Justice William Brennan, cautioned against endorsement of this version of prosecutorial discretion:

At best, [the materiality standard] places on the prosecutor a responsibility to speculate, at times without foundation, since the prosecutor will not normally know what strategy the defense will pursue or what evidence the defense will find useful. At worst, the standard invites a prosecutor, whose interests are conflicting, to gamble, to play the odds, and to take a chance that evidence will later turn out not to have been potentially dispositive.

* * *

The Court's standard also encourages the prosecutor to assume the role of the jury, and to decide whether certain evidence will make a difference. In our system of justice, that decision properly and wholly belongs to the jury. The prosecutor, convinced of the guilt of the defendant and of the truthfulness of his witnesses, may all too easily view as irrelevant or unpersuasive evidence that draws his own judgments into question. Accordingly he will decide the evidence need not be disclosed. But the ideally neutral trier of fact, who approaches the case from a wholly different perspective, is by the prosecutor's decision denied the opportunity to consider the evidence. The reviewing court, faced with a verdict of guilty, evidence to support that verdict, and pressures, again understandable, to finalize criminal judgments, is in little better position to review

the withheld evidence than the prosecutor.

Bagley , 473 U.S. at 702, 105 S.Ct. 3375 (Marshall, J., dissenting).

The Supreme Court of the United States has emphasized that "a prosecutor anxious about tacking too close to the wind" should "disclose a favorable piece of evidence" and "resolve doubtful questions in favor of disclosure." Kyles , 514 U.S. at 439, 115 S.Ct. 1555 (citing Agurs , 427 U.S. at 108, 96 S.Ct. 2392 ). Herein, that warning went unheeded by the Commonwealth, which now contends that the Robinson documents merely contained "gossip circulating in early November 1997 among a group of people who did not witness the murder and had scores to settle with Robinson," and which asserts now that the police investigation ultimately determined that Robinson was not involved in the Campbell murder. Brief for Commonwealth at 42. The Commonwealth also maintains that the prosecution is not required to disclose every "fruitless lead" followed by investigators. Id. at 27 (quoting Commonwealth v. Crews , 536 Pa. 508, 640 A.2d 395, 406 (1994) ).

This "fruitless lead" language is not grounded in precedent from the Supreme Court of the United States. It made its first appearance in this Court's jurisprudence in Crews , a case that centered upon a violation of former Pennsylvania Rule of Criminal Procedure 305(B)(1)(a), which required prosecutors to disclose to the defendant any exculpatory information material to the defense. The defendant in Crews did not raise a constitutional challenge under Brady . Nevertheless, over time, this limitation upon a prosecutor's duty to disclose has become a mainstay in this Court's decisions applying Brady . See, e.g., Commonwealth v. Paddy , 609 Pa. 272, 15 A.3d 431, 450-51 (2011) ; Ly , 980 A.2d at 75 ; Commonwealth v. Lambert , 584 Pa. 461, 884 A.2d 848, 857 (2005). Such a rule significantly erodes the purpose and spirit of Brady and its progeny, precedents that are designed to ensure that a defendant receives a constitutionally fair trial.

Characterizing a lead as "fruitless" necessarily begs the question — "fruitless" to whom? And what makes a lead "fruitless?" That it does not inculpate the defendant or that it does not fit in the Commonwealth's theory of the case? Permitting the Commonwealth to make such a prospective determination based upon its own assessment of evidentiary value diverges from the goals of fairness and justice that underlie Brady . Justice Marshall addressed this incompatibility, highlighting that "[e]vidence that is of doubtful worth in the eyes of the prosecutor could be of inestimable value to the defense, and might make the difference to the trier of fact." Bagley , 473 U.S. at 698, 105 S.Ct. 3375 (Marshall, J., dissenting). Additionally, Justice Marshall stressed that "it is the job of the defense, not the prosecution, to decide whether and in what way to use arguably favorable evidence." Id. See also Kyles , 514 U.S. at 440, 115 S.Ct. 1555 ("[Disclosure] will tend to preserve the criminal trial, as distinct from the prosecutor's private deliberations, as the chosen forum for ascertaining the truth about criminal accusations."). The Third Circuit in Dennis also criticized this Court's narrowing of Brady 's protection: "There is no requirement that leads be fruitful to trigger disclosure under Brady , and it cannot be that if the Commonwealth fails to pursue a lead, or deems it fruitless, that it is absolved of its responsibility to turn over to defense counsel Brady material." Dennis , 834 F.3d at 306.

Additionally, the Commonwealth's position that disclosure was unnecessary because the Robinson documents contain unsubstantiated gossip is inconsistent with the Commonwealth's own reliance upon comparable evidence to convict Natividad. Rutherford's and Smith's statements indicating that Robinson confessed to the Campbell murder were of the same nature and quality as the statements of Natasha Catlett and Robert Golatt describing Natividad's inculpatory statements, which the Commonwealth used to bolster its case without concern for the reliability of that evidence. Moreover, the Majority includes the Catlett and Golatt statements in the "overwhelming and intact evidence of [Natividad]'s guilt" upon which it relies to conclude that an alternative defense theory would not have been a stronger defense for Natividad than that presented at trial. Majority Opinion at 36. I reject the premise advanced here, that the materiality of evidence of such similar nature and quality hinges upon whether it supports the Commonwealth's theory of the case, or whether the remaining evidence was sufficient to suggest Natividad's guilt. The Commonwealth discredits some exculpatory statements as mere street gossip far removed from Brady 's materiality standard, while simultaneously bolstering its case against Natividad with other, inculpatory street gossip. It is difficult to take such a contradictory position seriously.

I criticize this approach "with an awareness of the difficulty of reconstructing in a post-trial proceeding the course that the defense and the trial would have taken had the defense" been privy to the suppressed evidence. See Bagley , 473 U.S. at 683, 105 S.Ct. 3375. Such a determination is

inherently speculative because one cannot tell with any certainty what effect the evidence would have had, precisely because the evidence was not introduced. The appellate court's review of ‘what might have been’ is extremely difficult in the context of an adversarial system. Evidence is not introduced in a vacuum; rather, it is built upon. The absence of certain evidence may thus affect the usefulness, and hence the use, of other evidence to which defense counsel does have access. Indeed, the absence of a piece of evidence may affect the entire trial strategy of defense counsel.

Daniel J. Capra, Access to Exculpatory Evidence: Avoiding the Agurs Problem of Prosecutorial Discretion and Retrospective Review , 53 FORDHAM L. REV. 391, 412 (Dec. 1984).

Even accounting for the suppressed Robinson materials, I concede readily and without equivocation that there might well be enough evidence remaining unscathed to sustain Natividad's conviction. But that is not our inquiry here. Not only is this not the proper materiality inquiry; it wholly ignores the fact that the jury would have been presented with an entirely different defense theory. That theory would have included perhaps the most exculpatory type of evidence — that another person confessed to the crime for which the defendant was charged. Our role is not to scrutinize the contents of the Robinson documents based upon the witness' motive or bias; that inquiry belongs to the jury. Unfortunately, the jury was "deprived of the ingredients necessary to a fair decision." Bagley , 473 U.S. at 694, 105 S.Ct. 3375 (Marshall, J., dissenting). The Commonwealth's suppression of the Robinson documents, which, if disclosed, would have allowed Natividad to present a defense focused upon his claim of innocence while advancing an alternative perpetrator theory, deprived Natividad of a "fair trial, understood as a trial resulting in a verdict worthy of confidence." Kyles , 514 U.S. at 434, 115 S.Ct. 1555.

Based upon the controlling precedent and the evidence in this case, my confidence in the outcome has been undermined, and I deem the suppression of the Robinson documents to violate Brady . That violation demands redress, lest the rule of Brady come to be viewed in this Commonwealth as a mere suggestion without consequence. I respectfully dissent.

Justice Donohue joins this dissenting opinion.
