WOLOHOJIAN, J. At issue is whether a judge erred in denying the Commonwealth's motion to vacate an order allowing the defendant's request for postconviction forensic deoxyribonucleic acid (DNA) testing pursuant to G. L. c. 278A. More specifically, the question is whether the judge was required to vacate his earlier order because the defendant died after the forensic testing had been ordered but before it was completed, or whether the judge retained discretion to allow the testing to go forward despite the defendant's death. We conclude that, in the absence of any statutory provision directly controlling these circumstances, the judge retained inherent authority to determine whether his earlier order should be vacated. We further conclude that, in the circumstances presented here, the judge did not abuse his discretion in denying the Commonwealth's motion to vacate.1

1 We acknowledge the briefs submitted in support of the defendant's argument by the Attorney General; the Committee for Public Counsel Services Innocence Program and the Massachusetts Association of Criminal Defense Lawyers; the Innocence Project, Inc.; and Judith Berberena, Jill Paiva, and Chandra Gregory, certain family members of victims killed by the New Bedford

Background. In 1989, the defendant was convicted of murder in the first degree and of larceny under $250. See Commonwealth v. Tanner, 417 Mass. 1, 6 (1994) (affirming conviction of murder in first degree after plenary review under G. L. c. 278, § 33E). No DNA evidence was introduced at the defendant's trial, nor was any forensic DNA testing or analysis performed on various items and samples collected in connection with the investigation of the murder; DNA testing was not generally available at the time. See Commonwealth v. Curnin, 409 Mass. 218, 221 (1991) (stating, in 1991, that "[t]he use of DNA testing for forensic purposes is of very recent origin").

We draw upon the background recited in our decision affirming the defendant's murder conviction, supplemented where necessary by the record. See Tanner, 417 Mass. at 2-3. The Commonwealth's evidence at trial showed that the victim had been strangled to death in a motel room on April 28, 1988. A stocking had been tightened around the victim's neck three times and was determined to be the cause of death. Shortly after the murder, the defendant told a friend that he thought he had killed someone, and that a woman had refused to have sexual intercourse with him because he did not have any money. He said "he had intercourse with her anyway and then strangled her with

highway murderer. We further acknowledge the amicus letter submitted by the Boston Bar Association.

his bare hands. To make sure, he said, he took a sock and strangled her again, 'pulled it real tight.'" Id. at 3. The defendant showed the friend several pieces of jewelry that he had taken from the woman, one of which he used to pay the friend for drugs. Later, the defendant offered the friend two additional rings he said he had hidden in a restaurant bathroom. Those rings were subsequently located by police.

The defendant testified in his own defense. While he admitted that he had been in the motel room with the victim on the night of the murder and that he had had sexual intercourse with her in exchange for forty dollars, he claimed that she was alive when he left and that another man (whom the defendant did not know but described in detail) entered the room after him.

More than thirty years after his convictions, the defendant, through his counsel at the New England Innocence Project, arranged for a private investigator to inspect and photograph evidence stored by the State police, including the stocking used to strangle the victim, scrapings obtained from beneath the victim's fingernails, bedsheets, towels, and hairs collected from the motel room, and the rings stolen from the victim.

Thereafter, in March 2022, the defendant filed a motion, pursuant to G. L. c. 278A, seeking postconviction DNA analysis

of the items photographed by the private investigator.2 While acknowledging that he had sexual contact with the victim on the night of the murder and thus that DNA analysis likely would confirm his presence, the defendant argued that the presence of another person's DNA would support his trial testimony that another man had been with the victim after the defendant left the motel room and could thus potentially lead to the identification of the perpetrator of the murder. The motion was supported by an affidavit from counsel detailing her unsuccessful efforts to obtain the district attorney's office's agreement for forensic testing of the items in the Commonwealth's custody. In addition, the motion was supported by an affidavit from the defendant in which he asserted that he was factually innocent of the victim's murder.

The Commonwealth did not file a written opposition to the defendant's motion. However, at one of two hearings on the motion, the prosecutor raised two specific objections. First, the prosecutor argued that one of the bloody towels, the rings, and the bed sheets might be contaminated because they had been introduced as exhibits and might have been handled by persons,

such as jurors, during the trial. Second, the prosecutor suggested that the defendant's proposed order granting the defendant's request for postconviction forensic testing might not be acceptable to the State police or to its crime laboratory (crime lab). In the end, the judge asked the parties to work together to submit a proposed order.
