Former Stoughton officer Matthew Farwell convicted of pregnant Sandra Birchmore's murder

Former Massachusetts police detective Matthew Farwell was convicted Tuesday in federal court of murdering Sandra Birchmore, who was pregnant when she died in 2021. Prosecutors said Farwell strangled the 23-year-old after learning a tipster had reported their improper relationship, which began when Birchmore was a teenager in a police youth program. He then staged her death to look like a suicide, prosecutors said. The case was investigated by the FBI.
