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 3

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. 4

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 5

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,

2 Not long before filing his motion for forensic testing, the defendant had been diagnosed with terminal brain cancer.
