Sandra Birchmore believed things were getting better. Matthew Farwell brought ginger ale to her apartment. She texted a friend that he was coming around. She was contacting lawyers. She was building a plan for child support. She was preparing for a future with the child she was carrying — a future she believed was finally within reach.

Farwell was allegedly having different conversations entirely.

According to federal prosecutors, he told one person that if Sandra did not end the pregnancy, he would "take care of the problem himself." He told another he needed to "put crazy back in the bag." He told a third that "the problem was going to take care of itself." Three people. Three conversations. All allegedly pointing toward a man who had decided that a pregnant twenty-three-year-old — the same girl he allegedly began a relationship with when she was fifteen and enrolled in his police youth program — was a problem to be eliminated.

On January 20, 2021, Sandra's friend called the Stoughton Police Department and reported Farwell's involvement with Sandra. The employee who took the call told Farwell. Eleven days later, Sandra was dead.

At 9:27 PM on February 1, Farwell entered her Canton apartment building. At 9:56 PM, he left. Twenty-nine minutes. Sandra's phone recorded its final movements while he was still inside. She was found three days later in the same clothes. Her death was classified as something other than homicide for years.

The forensic evidence prosecutors have since assembled tells a different story. Farwell's DNA on the duffel bag strap they say was used to strangle her. His sperm cells in her underwear — contradicting his claim of months without contact. An injury to her right clavicle sustained while she was alive, matching a buckle behind her head. A broken pink flamingo necklace — one Sandra wore regularly — tangled in her hair on the bedroom floor. And a reenactment at a private gathering where an inebriated Farwell reportedly demonstrated how she supposedly died, describing details no one outside the investigation should have known.

DNA testing confirmed Farwell was not the biological father of Sandra's unborn son. But both he and Sandra believed he was. Prosecutors say that belief — combined with Sandra's growing willingness to tell the truth about how their relationship began — is what made her a threat he allegedly could not allow to speak.

Sandra put her trust in the police. They allegedly broke it in every way a person can be broken.

Farwell has pled not guilty. His defense maintains Sandra took her own life.
