Va. Code § 19.2-213
At the conclusion of its investigation and deliberation, a special grand jury impanelled by the court on its own motion or on recommendation of a regular grand jury shall file a report of its findings with the court, including therein any recommendations that it may deem appropriate, after which it shall be discharged. Such report shall be sealed and not open to public inspection, other than by order of the court.
A majority, but not less than five, of the members of a special grand jury convened upon request of the attorney for the Commonwealth must concur in order to return a "true bill" of indictment. A "true bill" may be returned upon the testimony of, or evidence produced by, any witness who was called by the grand jury, upon evidence presented or sent to it.
