Former Stoughton police officer Matthew Farwell, who is accused of murdering 23-year-old Sandra Birchmore, who was pregnant, in 2021, has also been charged with causing the death of Birchmore’s unborn child.

Farwell, who is no longer a police officer, is accused of murdering Birchmore in Canton. According to the federal indictment, prosecutors allege he strangled her in her apartment and made it look like a suicide.

Prosecutors said Farwell began a sexual relationship with Birchmore when she was 15 and in the police department’s youth mentor program, where he was an instructor.

Prosecutors said Birchmore told Farwell she was pregnant with his child, and about one month later, her killed her. Her death was initially declared a suicide before the intervention of federal prosecutors.
