A federal jury in Boston has begun deciding whether former Stoughton police detective Matthew Farwell killed Sandra Birchmore, the 23-year-old woman prosecutors say he began sexually abusing when she was 15, and staged her death to look like a suicide. Jurors heard closing arguments on Friday, November 6, deliberated for a little more than three hours, and were sent home for the weekend without a verdict. Deliberations resume on Monday, November 9, at the John Joseph Moakley U.S. Courthouse, where Chief U.S. District Judge Denise J. Casper will check in with the panel as it weighs charges that could send Farwell, 40, to prison for life.

Farwell has pleaded not guilty to killing a witness and to causing the death of an unborn child, and he declined to testify in his own defence. Prosecutors say he killed Birchmore on February 1, 2021, in her apartment in Canton, Massachusetts, after learning she was pregnant with what he believed was his child, because she was about to expose years of abuse that began when she was a teenager in a police youth programme. The defence says Birchmore died by suicide, that the physical evidence does not prove otherwise, and that there is no proof she was about to report Farwell to anyone. Every charge in this report is an allegation that the jury — not prosecutors, and not this newsroom — will now decide.

What happened in court on Friday
Friday was the trial's decisive day. After the defence rested on Wednesday, November 4 — with Farwell telling Judge Casper he would not take the stand — each side received 90 minutes for closing arguments on Friday morning. Federal prosecutor Brian Fogerty told jurors Farwell went to Birchmore's apartment to 'clean up his mess' — the mess, prosecutors say, of years of abusing a teenager he met through his own department's youth programme, which was about to be exposed by her pregnancy. 'He went to clean up the mess he had created years earlier,' Fogerty argued. 'Clean up the mess by taking Sandra's life.' Judge Casper then instructed the jury on the law, and deliberations began on Friday afternoon. There is no deadline: the jurors may take as long as they need, but their verdict on each count must be unanimous.

The prosecution case the jury is weighing
Prosecutors say the relationship began through the Stoughton Police Explorers, a youth programme designed to teach children about law-enforcement careers, where Farwell was an instructor and Birchmore was a participant from the age of 12. They allege he began sexually abusing her at 15, when he was 27, and used his position as a married detective to keep her silent for years. Text messages read at trial showed Birchmore telling a friend in October 2020, 'I gave him an ultimatum and I'm getting his baby,' and sending Farwell a poster photograph on December 28, 2020, reading 'Congrats we are goin' to be parents!' Farwell replied in one message, 'You are truly the worst person on the face of the earth,' and in another, 'You extorted me to get what you wanted.' An assistant principal who worked with Birchmore at the Sharon school district, Cheryl Carlson, testified Birchmore was excited about the pregnancy and wanted the baby 'to have someone to love.'

The timeline evidence was central. An FBI digital forensic examiner, Christopher Beckstrom, told jurors Birchmore's phone locked for the last time at 9:13 p.m. on February 1, 2021. Surveillance video showed Farwell, in a hooded sweatshirt and face mask, entering her apartment building at 9:14 p.m., after Birchmore texted him that her door was open. Her phone recorded eight steps at 9:40 p.m. and no steps after that, and Farwell was filmed leaving the building at 9:43 p.m. An FBI agent testified Birchmore usually texted Farwell after his visits — that night, she did not. Prosecution strangulation expert Dr. William Smock testified the death was a homicide: he said a fracture of the hyoid bone in Birchmore's neck rarely happens in suicides, and that an injury on her chest, which he attributed to the clasp of the duffle-bag strap, suggested the scene had been staged. Jurors also heard that on January 20, 2021, Stoughton dispatcher James Fitton received a call from a woman alluding to a relationship between Farwell and her friend, that Farwell became 'visibly and audibly upset' when told, and that Fitton threw away his note of the call after a supervisor told him to forget about it.

Farwell is charged, not convicted. He has pleaded not guilty, his lawyers say Sandra Birchmore died by suicide, and DNA testing at trial excluded him as the father of her unborn child. He is presumed innocent unless the jury finds the government has proved its case beyond a reasonable doubt.
The defence case
Defence attorney Kimberly Stevens did not deny that Farwell had an affair with Birchmore. Instead, the defence attacked how she died and why. Its experts directly contradicted the prosecution's: Dr. Thomas Andrew, a former chief medical examiner for New Hampshire, testified that all the factors of the death pointed to suicide — 'This is not manual strangulation,' he said — and anthropologist Heather Garvin testified the hyoid fracture does not definitively prove homicide. Forensic scientist Alicia McCarthy said she could not conclude with certainty that the strap clasp caused the chest injury. The defence pointed to an apparent suicide note in a journal Birchmore wrote in 2017 and to her internet search, days before she was found, for 'What color is the suicide ribbon.' Farwell told the state trooper who first investigated, Matthew Dunne, that he went to the apartment on February 1 to break up with Birchmore and tell her the baby was not his — and DNA testing did exclude Farwell as the father; the father was identified in testimony as Jason Pickard, an Air Force defence contractor Birchmore met while he was recruiting for the Army Reserve, who said he had urged her to report Farwell but alerted no one himself.

How a closed suicide case reached a federal jury
Birchmore was found dead on February 4, 2021, when police carried out a welfare check at her Canton apartment after she did not show up for work; she was found hanging in a seated position from a door handle by a duffle-bag strap. Local authorities initially determined the manner of death to be suicide, and Massachusetts prosecutors never brought charges. The state medical examiner's office later changed the finding to 'undetermined.' Only after the FBI opened its own investigation in 2023 did the case move: a federal grand jury indicted Farwell on August 28, 2024, on the witness-killing charge (brought under the federal witness-tampering statute, 18 U.S.C. § 1512), and in 2025 prosecutors added the charge of causing the death of an unborn child. The trial itself began with jury selection on October 6 — one of the largest jury pools Boston's federal court has seen — opening statements on October 9, and testimony from October 13, including officers, medical experts, investigators and Birchmore's family and friends. Trooper Dunne also testified that his first interview with Farwell was neither recorded nor noted, and that a second interview days later, conducted with a supervisor who knew Farwell, was likewise not documented in notes — gaps the defence and prosecution each used for their own case.

Why this verdict matters beyond Stoughton
Whatever the jury decides, the case has already become a national test of two things American communities argue about far beyond Massachusetts: whether police-run youth programmes carry enough safeguards when an officer is accused of exploiting a teenager inside one, and whether an initial investigation that gets a death wrong can still be corrected by the system that made the error. Here, the first ruling was suicide, no local charges followed, and it took a changed medical finding, an FBI inquiry two years later and a federal indictment three and a half years after the death to put the questions to a jury at all. For families in the Punjabi diaspora and every other community whose children join police explorer posts, cadet schemes and similar programmes across the United States, the safeguards question is the lasting one: who supervises the adults, and where does a young participant report harm when the alleged abuser is the officer in charge?

What happens next
Deliberations resume on Monday, November 9, with Judge Casper checking in on the jury; there is no set timetable for a verdict. If the jury convicts Farwell on either count, he faces life in federal prison and sentencing would follow. If it acquits him, he walks free of the federal charges. If the jurors cannot agree unanimously, Judge Casper may declare a mistrial, and federal prosecutors would have to decide whether to try the case again. Awaaz Punjab will report the verdict when it is returned.
