‘Sandra’s first sexual experience involved a crime’: A former Massachusetts cop goes on trial

Former Officer’s Trial Centers on Sandra Birchmore’s Death

Healfromzero.com – Sandra’s first sexual experience is central to the federal trial of former Stoughton police officer Matthew Farwell, who is accused of killing Sandra Birchmore in 2021. Prosecutors say Farwell exploited Birchmore for years after meeting her through a police youth program, then killed her when she became pregnant and could expose their relationship.

Birchmore, 23, was found dead on February 1, 2021, in her Canton, Massachusetts, apartment. A duffel bag strap was around her neck and attached to a closet door handle. Her death was initially ruled a suicide by local and state authorities, but federal charges were filed against Farwell three years later.

Farwell, now 40, has pleaded not guilty and has been held since his August 2024 arrest. If convicted, he could face life in prison. The trial is being held at Boston’s John J. Moakley Courthouse and is expected to last about a month.

Prosecution and defense offer opposing explanations

Federal prosecutors say Farwell groomed and abused Birchmore over many years while holding a position of authority in her life. They allege that he killed her to prevent her from revealing information about their relationship, particularly after she became pregnant.

Assistant U.S. Attorney Torey B. Cummings told jurors that Farwell first had sex with Birchmore when she was 15 and he was 27. She had joined the Stoughton Police Department’s Explorers program, which was intended to connect young people with structure, mentorship and positive adult role models.

“Sandra’s first sexual experience involved a crime.”

Prosecutors say Farwell continued seeing Birchmore for sex, including while he was on duty. They argue that he feared the consequences if Birchmore disclosed what happened between them.

“She could end his life with the information she had, so he decided to end hers first.”

Farwell’s attorney, Kimberly Stevens, acknowledged that he had an affair with Birchmore while married and made serious mistakes. But she argued that prosecutors cannot prove he killed Birchmore and said her death was suicide.

Stevens told jurors that Birchmore was isolated, anxious and under financial strain, with less than $3 in her bank account. The defense says she was in an emotional crisis after Farwell ended their relationship on the night she died.

“Impulsive act of despair.”

Relationship began through youth police program

Birchmore entered the Explorers program in 2010 after her mother hoped it would give her greater stability and support. Prosecutors said Birchmore had challenges at school, had been diagnosed with ADHD and struggled to build friendships. Her father was not involved in her life, and her mother had health problems.

According to prosecutors, Birchmore became highly interested in police work and spent substantial time around the department. She was eager for officers’ approval, they said, and developed trust in Farwell as he became involved in her life.

In late 2012, Farwell sent Birchmore a Facebook friend request and later tutored her at a local library. Prosecutors contend that what began as mentoring became sexual exploitation. Federal law prohibits a person at least four years older from engaging in a sexual act with someone under 16.

The testimony has raised questions about safeguards in youth programs involving law enforcement. Prosecutors say the authority and access provided through the Explorers program gave Farwell an opportunity to exploit Birchmore rather than support her.

Pregnancy is part of the federal allegations

Farwell is charged with killing a witness or victim, with prosecutors alleging that he acted to keep Birchmore from potentially implicating him. He also faces a charge connected to her pregnancy under a federal law protecting unborn children.

DNA testing later excluded Farwell as the biological father of Birchmore’s unborn child. Prosecutors contend, however, that Farwell believed he was the father at the time of her death and that the belief influenced his alleged motive.
