BERRY, J.

This appeal follows a jury-waived trial in which the trial judge found the defendant guilty on seven indictments charging forcible rape of a child and one indictment charging assault with intent to rape a child. See G.L. c. 265, §§ 22A, 24B.

One of the issues presented by the defendant on appeal is unique to the first two rape indictments. These two charges arise out of acts of digital and oral rape of the victim that occurred during a cross-country trip at an unknown location in a State outside Massachusetts. The Commonwealth submits that, because the trip originated in Massachusetts, with a return to Massachusetts where the defendant continued to engage in acts of rape against the victim, and because no State can be determined as the locus of the crimes, then Massachusetts must be presumed to have jurisdiction over, and venue for trial of, these two rapes. We address this issue in part 1, infra.

The other appellate issues, involving the remaining five convictions of forcible rape and the one conviction of assault with intent to rape, regard the defendant's claims that: (a) there was insufficient evidence proving the element of force required under G.L. c. 265, § 22A ; and (b) the prosecutor's closing improperly referenced certain entries in the victim's medical records, which records had been admitted by agreement. We address these issues in parts 2 and 3, infra.

The trial evidence may be summarized as follows. The defendant and his family lived next door to the victim. The victim's stepmother is the defendant's niece. Beginning when the victim was eleven years old, and continuing until she was fourteen (from 2002 through March, 2005), she spent a great deal of time at the defendant's house in Carver, playing with two of the defendant's sons, who were close to her in age. The defendant, who was in his early fifties, regularly drove his sons and the victim to school, and the victim went over to the defendant's house three or four days per week after school. In addition, from time to time during weekdays, the victim slept over at the defendant's house, and also stayed there on many weekends.

When she was eleven years old, the victim traveled on a cross-country trip to Oregon in the defendant's family camper with the defendant, his wife, and three of his sons. One night as she slept, the defendant came to the victim's bed in the camper. The defendant removed her shorts and put his fingers inside her "private," moving his fingers in and out. Then, the defendant spread the victim's legs, put his face between her legs, and placed his tongue in her vagina. The victim pretended to remain sleeping. The victim recollected that the events happened during travel to Oregon, not on the way back to Massachusetts.

The defendant had done similar things to the victim before the Oregon trip, when she stayed at the defendant's house. Sometimes during these events, the victim would tell the defendant to stop, and he would. Otherwise, he would simply stop on his own and return to his bedroom. The victim did not tell anyone what had happened, did not know that these things were wrong, and just "accepted it."

After the Oregon trip, the victim continued spending time during the day, and sleeping overnight, at the defendant's house. In testifying about the rapes, the victim, in certain descriptions of the events, connected the rapes to the rooms in the house where the acts were done. There was a finished basement room that two of the defendant's sons used as a bedroom. On one night, the victim remembered lying on the floor near one of the boys' beds when the defendant came downstairs. As he knelt on the floor, the defendant first placed his fingers in the victim's vagina, and then separated her legs and put his tongue into her vagina, in the manner he had on the cross-country trip. The living room was the place of other rapes, again in which the defendant engaged in digital penetration of the victim's vagina and oral sex. (The defendant often slept in a chair in the living room because he had lymphedema, an ailment which causes swelling of his extremities, particularly his legs.)

In March, 2005, when the victim was fourteen years of age, there was a final indecent assault upon the victim. Just before Easter, the victim, with her half-brother, stayed over at the defendant's house on a school night. As the victim was sleeping on the living room couch, close to midnight, the defendant, who had been in his chair, approached her. He began to place his fingers in her vagina. She told him that she had to be up early for school the next day. The defendant stopped and returned to his chair. However, a few hours later that night, the defendant approached again and began to climb on top of the victim. She placed her hands against his chest, pushed him away, and said no. The defendant stopped. Thereafter, the victim disclosed the defendant's acts, and an investigation followed.

In addition to her testimony describing the assaults upon her, the victim related a series of conversations she had had with the defendant, including his statements to her that: he had had similar experiences with the victim's stepmother; he had not had sex with his wife in twenty years; and he loved the victim so much that his wife was jealous.

The defendant testified. He denied the allegations. The defendant stated that he had not been present at his house during weekends, but rather was working on Cape Cod. He would, he said, leave his house in Carver on Wednesdays and stay on Cape Cod until Monday mornings. The defendant's wife testified that there was only one non-weekend night when the victim stayed at the defendant's house, and that this was a March, 2005, sleepover (which was the night of the final sexual assault with intent to rape). However, on cross-examination, the defendant's wife acknowledged that the victim may have slept over on a weeknight during the summers, and that the victim was at her house almost every day.

Another prong of the defense rested on the defendant's medical condition. The defendant testified that he cannot kneel for long periods of time, and that, if he does, he will require assistance standing upright, or it may take a couple of minutes for him to rise. It was suggested that this condition would have hindered the defendant from perpetrating the indecent acts described by the victim.

1. The out-of State rapes, a. The jurisdictional issue. As previously noted, two of the acts of rape, which were the predicates for the first two indictments, occurred outside of Massachusetts. The defendant challenges his convictions of these two crimes on the basis that the indictments were improperly returned in Massachusetts, and that our courts lacked jurisdiction to try him for these offenses. Given the lack of Massachusetts jurisdiction, the defendant contends, his constitutional rights were violated.

"It is elementary that it must be shown that jurisdiction lodged in the courts of Massachusetts before the defendant can be found guilty of the offence charged." Commonwealth v. Fleming, 360 Mass. 404, 406 (1971). "Criminal laws have no extraterritorial validity. They will not be enforced outside the jurisdiction of the sovereign by whose authority they are enacted. That is a general principle." Commonwealth v. Booth, 266 Mass. 80, 84 (1929). "The general rule, accepted as 'axiomatic' by the courts in this country, is that a State may not prosecute an individual for a crime committed outside its boundaries." Vasquez, petitioner, 428 Mass. 842, 848 (1999). Accord Commonwealth v. DiMarzo, 364 Mass. 669, 671 (1974) ("With reference to the question of jurisdiction, there can be no doubt that the judge had no power to try the defendant for crimes committed out of State"); Commonwealth v. Gilbert, 366 Mass. 18, 28 (1974) (the jurisdiction of a Massachusetts court depends on "[w]hether a criminal act occurred within the territorial boundaries of the Commonwealth").

Notwithstanding these jurisdictional principles, the Commonwealth submits on appeal that these two rapes were subject to prosecution in Massachusetts because they fall within a very limited exception allowing a State extraterritorial jurisdiction over a criminal offense: the "effects" doctrine, which was described by Justice Holmes in Strassheim v. Daily, 221 U.S. 280, 285 (1911). According to the Holmesian analysis defining this doctrine, "[a]cts done outside a jurisdiction, but intended to produce and producing detrimental effects within it, justify a State in punishing the cause of the harm as if he had been present at the effect. . . ." Ibid. See the analysis of the effects doctrine in Vasquez, petitioner, 428 Mass. at 848-849, discussed infra.

For the reasons that follow, we determine that the effects doctrine is not applicable to these two out-of-Massachusetts extra-territorial rapes. The Commonwealth's invocation of the effects doctrine in this case would not only be in conflict with the afore-said existing jurisdictional precedent, but also would be so expansive a reading of the effects doctrine as to stretch Massachusetts criminal law jurisdiction into a hitherto unrecognized realm.

Both Justice Holmes's Federal enunciation of the effects doctrine in Strassheim and the Massachusetts analysis of the doctrine in Vasquez arose in the context of habeas corpus challenges to extradition warrants, and focused on whether a crime had been committed within the jurisdiction of the requesting State from which the to-be-extradited defendant was a fugitive. In Strassheim, the issue was whether a Michigan indictment, for which the Illinois extradition warrant was requested, rested on predicate acts that occurred in Michigan. As Justice Holmes wrote, such predicate acts did occur in Michigan: "Thus in this case offering the bid and receiving the acceptance were material steps in the scheme, they were taken in Michigan, and they were established in their character of guilty acts when the plot was carried to the end. . . ." Strassheim, 221 U.S. at 285. These in-State acts of tendering a fraudulent bid and its acceptance were a part of the offense elements of the underlying crime of obtaining money by false pretenses. Therefore, Justice Holmes evidently reasoned that, although certain of the defendant's acts proving offense elements occurred outside Michigan, there was, nonetheless, jurisdiction in Michigan because the predicate acts proving offense elements occurring outside Michigan, coupled with the in-State acts, were intended to produce, and did produce, detrimental effects directly within Michigan. In contrast, in this case, no predicate acts proving offense elements of the crime of rape occurred within Massachusetts. Rather, all acts in the out-of-State rapes in the camper were accomplished at some unknown place outside of Massachusetts. Hence, unlike the in-State predicate acts involving the bid and acceptance offense elements of obtaining money by false pretenses in Strassheim, in the case at bar, no Massachusetts-based predicate act proving an offense element of the rapes occurred within Massachusetts, and under the effects doctrine, the out-of-State acts, standing alone, cannot be deemed to have been intended to produce a direct detrimental effect within Massachusetts. We do not read Strassheim as making the effects doctrine so broad as to empower a State to exercise jurisdiction where all acts in furtherance of the crime and all offense elements of the crime are committed wholly outside the borders of the State.

The analysis by the Supreme Judicial Court in Vasquez leads to the same conclusion. Similarly to Strassheim, the Vasquez case presented an extradition issue, there concerning validity of a Massachusetts extradition warrant issued upon a request from Oregon based upon the petitioner's indictment for criminal non-support of his children. Vasquez, petitioner, 428 Mass. at 842-843. The petitioner contended that the requesting State of Oregon had no jurisdiction over the crime. This was so, the petitioner argued, because he lived in Massachusetts, where the support order had issued, whereas the resulting indictment for failure to pay under the support order was returned in Oregon, the State to which his former wife and children had moved, and in which he had never set foot. The Supreme Judicial Court rejected a habeas corpus challenge to the extradition warrant, on the basis that after extradition the petitioner would have the right to process of law to litigate a jurisdictional challenge to the Oregon indictment. Id. at 847. The court deemed the deprivation of the petitioner's liberty under the warrant to be proper unless "Oregon's requisition were egregiously devoid of even a colorable claim of legislative jurisdiction." Ibid. Of import to the instant case, the Vasquez court then proceeded with its analysis under "[t]he general rule, accepted as 'axiomatic' by the courts in this country, [which] is that a State may not prosecute an individual for a crime committed outside its boundaries." Id. at 848, citing Nielsen v. Oregon, 212 U.S. 315, 321 (1909), and Huntington v. Attrill, 146 U.S. 657, 673 (1892). Invoking the exception to the general rule, the Vasquez court viewed the effects test as a basis for the lawful exercise of criminal jurisdiction by Oregon, "on the theory that, although the offending parent was outside the State at the time he committed the crime, the detrimental effect occurred where the child[ren] resided." Vasquez, petitioner, supra at 849.

In this case, the Commonwealth's argument is that Massachusetts jurisdiction spreads so far as to envelop these out-of-State criminal acts because the defendant and the victim are Massachusetts residents, left this State together (with other family members), and returned to Massachusetts where the defendant continued his sexual abuse of the victim., But this pattern of potentially recurring criminal acts is a fact pattern theoretically present in a host of out-of-Massachusetts offenses committed by a putative resident defendant who leaves this State with a person against whom the putative defendant commits criminal acts outside Massachusetts, only to return to Massachusetts and continue to engage in criminal acts against the same person. The effects doctrine does not have so all-encompassing a reach.

In conclusion, the extraterritorial limitation on a State's jurisdictional power to reach and prosecute crimes committed outside its borders, in our view, defeats the Commonwealth's contentions in this case. The effects doctrine does not save the jurisdictional defect in this case with respect to the first two rape indictments.

b. The venue statute. The Commonwealth also invokes G.L. c. 265, § 24A, as a jurisdictional basis. But that statute deals only with venue, and does not confer jurisdiction. Specifically, § 24A conveys dual venue for trial of a crime in which a victim is transported within Massachusetts from one county to another in order to commit the crime. See Commonwealth v. Libby, 358 Mass. 617, 619-620 n. 2 (1971); Commonwealth v. Dineen, 70 Mass. App. Ct. 1, 3 (2007).

2. The offense element of force in the remaining rape charges. The defendant also claims that the Commonwealth failed to introduce sufficient evidence concerning the element of force required for the offense of rape of a child by force. See G.L. c. 265, § 22A; Commonwealth v. Thayer, 418 Mass. 130, 132 (1994). This claim is unavailing. Under the governing standard, viewing the totality of the evidence in the light most favorable to the Commonwealth, we conclude that the evidence sufficiently proved the element of force. See Commonwealth v. Latimore, 378 Mass. 671, 676-678 (1979).

Proof of the force element of rape under G.L. c. 265, § 22A, may be established by physical force or constructive force. "[I]n this Commonwealth, unless the putative victim has been rendered incapable of consent, the prosecution must prove that the defendant compelled the victim's submission by use of physical force; nonphysical, constructive force; or threat of force" (emphasis added). Commonwealth v. Lopez, 433 Mass. 722, 728-729 (2001). See Commonwealth v. Helfant, 398 Mass. 214, 220-222 (1986); Commonwealth v. Caracciola, 409 Mass. 648, 653 (1991). In this case, the rape convictions are sustainable on both the physical force and constructive force theories of proof.

a. Physical force. The evidence demonstrated actual physical force inflicted upon the victim by the defendant in those digital rapes during which the physical intrusion of penetration was perpetrated while the young victim was asleep. "[I]t has been held that, if a man has carnal intercourse, using so much force as is necessary, with a woman who is incapable of consenting, by reason of sleep . . . he may be convicted of rape." Commonwealth v. Roosnell, 143 Mass. 32, 40 (1886). Accord Commonwealth v. Fionda, 33 Mass. App. Ct. 316, 321-323 (1992) (correct jury instruction that if, by reason of sleep, victim is incapable of consenting, then sexual act is done without valid consent of victim); Commonwealth v. Moniz, 43 Mass. App. Ct. 913, 913-914 (1997) (sufficient force where penetration was accomplished without opportunity for victim to resist). See also Commonwealth v. Feijoo, 419 Mass. 486, 493 (1995); Commonwealth v. Vasquez, 55 Mass. App. Ct. 523, 534-536 (2002).

Actual force was also present in the oral rapes, where the defendant pulled the victim's legs apart and positioned himself against her spread legs while he engaged in oral sex.

b. Constructive force. The convictions would be sustainable in any event under the alternative theory of proof of nonphysical constructive force. See Commonwealth v. Lopez, supra. Among the spectrum of factors which may be considered on the question of the sufficiency of the evidence proving constructive force in accomplishing a rape against a child is the historical and contextual relationship between the victim and the defendant, as well as the manner and means by which the rape is perpetrated, which factors, among others, bear on whether the victim's ability to resist the rape was overborne or negated. In essence, the focus is on the circumstances "in which the victim is placed, the impact of those circumstances . . . on the victim's power to resist and the defendant's conduct[,] all [of which] are relevant to the determination whether conduct complained of by the victim was accomplished by force and against the victim's will." Caracciola, 409 Mass. at 651.

In this case, a confluence of circumstances yielded sufficient evidence of constructive force upon the vulnerable victim who was the object of the defendant's digital and oral intercourse against her will and without any meaningful power to resist. The defendant took advantage of the young victim as she slept in his house, where the defendant was an authority figure, and the victim was in the care of the defendant and his wife. The defendant gained an additional advantage over the victim because the victim was his step-niece, and she trusted him. There was a great disparity in age between the defendant and the young victim, and the defendant, a much larger person than the victim, would have a commanding physical presence. "By looking to the child's age and size, a [fact finder] could reasonably have inferred that the sexual intercourse took place by force and against her consent." Commonwealth v. Melchionno, 29 Mass. App. Ct. 939, 941 (1990).

The defendant argues that such factors still do not add up to the level of constructive force, because the victim stated that she was not threatened by the defendant and was not scared by him. However, that the young victim denied fear, and instead sought to suppress the effects of the rapes by pretending to sleep during the rapes, professing to accept the continual assaults as acts which "didn't affect me" because she was so young that she "didn't think anything was wrong with it [and] just accepted it," does not mean that the evidence was not sufficient to show that the rapes were committed against the victim's will, or that her power to resist was not overborne by the defendant. See Commonwealth v. Sherry, 386 Mass. 682, 688 (1982); Commonwealth v. Caracciola, supra. Indeed, that the victim endured the rapes with resignation and with no will to resist the defendant's sexual exploitation is reflective of the very nature of the application of constructive force with respect to the crime of rape of a young person.

3. The medical records issue. The defendant claims that there was error in the admission of the victim's medical records because the records were not redacted to exclude hearsay statements referring to the defendant as the perpetrator of the sexual assaults, and to delete statements in the records that sexual crimes had been committed. In related complaints, the defendant criticizes the prosecutor's closing argument, which included comments about the victim's statements in the unredacted records, and objects that the trial judge reviewed the records.

The defendant agreed to the admission of the records, and did not request any limitation on their use. Moreover, the defendant stated no objection to the prosecutor's argument or to the trial judge's statement that she intended to read the records. Hence, we review to determine whether any error gave rise to a substantial risk of a miscarriage of justice.

Given the stipulated admission, it is hard to see error. But, even addressing the second level of review concerning whether any error led to a substantial risk of a miscarriage of justice, we discern no such risk in the prosecutor's references or in the trial judge's review of the records.

First, as previously noted, the medical records were admitted with the defendant's agreement. Second, the entries in medical records documenting the victim's medical history and treatment at the hospital, medical opinions, and diagnosis were admissible under G.L. c. 233, § 79G. See Commonwealth v. DiMonte, 427 Mass. 233, 241-242 (1998); Commonwealth v. McCready, 50 Mass. App. Ct. 521, 523 (2000). Third, the prosecutor's references to the victim's hearsay statements were neither extensive nor extreme, but rather were limited to highlighting the consistency in the victim's description of the rapes. Fourth, the trial judge, who was the fact finder, is presumed to know the law and could read the records without being unduly influenced by any hearsay statements appearing in the unredacted medical records. See Commonwealth v. Batista, 53 Mass. App. Ct. 642, 648 (2002) ("A trial judge sitting without a jury is presumed, absent contrary indication, to have correctly instructed [her] self as to the manner in which evidence is to be considered in [her] role as factfinder").

4. Conclusion. On the first two charges of rape of a child by force, the judgments are reversed, the guilty findings are set aside, and the indictments are to be dismissed. The judgments of conviction on the remaining indictments are affirmed, and the matter is remanded accordingly for resentencing.

So ordered.
