A federal jury in Boston began deciding on Friday whether former Stoughton police detective Matthew Farwell murdered Sandra Birchmore, a 23-year-old woman who was pregnant when she died in February 2021. The case has shaken a small Massachusetts police department and raised hard questions about a death first ruled a suicide.

Jurors in the Sandra Birchmore trial deliberated for a little more than three hours on Friday before going home for the weekend. They return on Monday, when Judge Denise Casper will check in with them as they weigh charges that could send Farwell, 40, to prison for life.

Key Points

• Jurors began deliberating on Friday, November 6, 2026, in federal court in Boston after a nearly month-long trial with about 50 witnesses and 500 exhibits.
• Former Stoughton detective Matthew Farwell, 40, is charged with killing a witness and killing an unborn child. He has pleaded not guilty and declined to testify.
• Prosecutors say Farwell killed Sandra Birchmore, 23, who was pregnant with what he thought was his child, on February 1, 2021, and staged her death as a suicide.
• The defence says Birchmore died by suicide and that there is no evidence she was about to tell law enforcement about the abuse prosecutors describe.
• Massachusetts State Police first called the death a suicide, but the medical examiner later changed it to "undetermined", and the FBI opened its own inquiry in 2023.

What Happened

The trial reached its decisive stage on Friday, when closing arguments were delivered and the case was handed to the jury. Opening statements had begun on October 9, and the defence rested on November 4 after weeks of testimony from officers, medical experts, Birchmore's family and friends, and investigators who reconstructed her final days. Farwell did not take the stand. After a little more than three hours of discussion, jurors were sent home for the weekend without a verdict. There is no deadline, and they may take as long as they need to reach a unanimous decision on each charge.

Background and Context

Birchmore was found dead on February 1, 2021, with a strap around her neck. Massachusetts State Police concluded she had died by suicide, but doubts grew as more emerged about her relationship with Farwell, and the medical examiner later changed the manner of death to "undetermined". Local prosecutors never brought charges, and it was not until 2023 that the FBI began looking into her death. A federal grand jury indicted Farwell on August 28, 2024, on charges of killing a witness and killing an unborn child, which carry a possible life sentence.

Prosecutors say the relationship began when Birchmore was 15 and taking part in the Stoughton Police Explorers youth programme, where Farwell was one of the officers working with the young participants. They say he began sexually abusing her then, and that the abuse continued for years, with Farwell using his position as a detective to keep her silent. By early 2021, they say, she was pregnant with what she believed was his child and was preparing to tell others about the relationship.

The Sandra Birchmore Trial: The Two Cases Before the Jury

The prosecution's case rests on two pillars: the physical evidence and the story of the relationship. Prosecutors told jurors the way Birchmore's body was found, and the state of the strap and the room, did not fit with a person taking her own life. They presented expert testimony to support that claim, alongside messages and testimony from people who knew Birchmore and described her state of mind in her final days.

Above all, prosecutors gave the jury a motive. They told jurors Farwell killed Birchmore to "clean up his mess" — to stop her revealing years of abuse that began when she was a child in a police youth programme. In their telling, the pregnancy made the danger immediate: she was carrying what Farwell believed was his child, and the secret he had kept for years was about to come out. The defence says Birchmore died by suicide, that the evidence does not prove otherwise, and that there is no proof she was going to report Farwell.

Reactions and Quotes

In closing, prosecutors put the case in blunt terms, telling jurors Farwell killed Birchmore to "clean up his mess" after abuse that began when she was 15 — a deliberate act to protect himself, not a moment of panic. The defence countered that the government had not proved its case and that there was no evidence she planned to report him. Judge Denise Casper will check in with jurors when they return on Monday. Neither side has commented on the deliberations, and the court has given no indication of how long the jury may take.

Why It Matters

The trial matters well beyond the fate of one former detective. It tests whether the justice system can hold a police officer accountable for abusing a child who trusted him through a youth programme run by his own department, and whether a death first written off as suicide can be re-examined when the evidence points the other way. It also exposes the gaps that open when the first investigation gets it wrong: state police called it a suicide, no local charges were ever filed, and only a changed medical finding, an FBI inquiry in 2023 and a federal indictment in 2024 brought the case to trial.

What Happens Next

Deliberations resume on Monday, when the jury returns to the federal courthouse in Boston. Jurors must reach a unanimous verdict on each charge and may ask the judge questions or request exhibits as they work. If they convict Farwell on either count, he faces life in prison, with sentencing to follow. If they acquit him, he walks free of the federal charges. If they cannot agree, Judge Casper may declare a mistrial, and prosecutors would have to decide whether to try the case again.
