Ex-officer convicted of killing Sandra Birchmore to keep Massachusetts woman quiet about sex abuse

Key Points:

• Former Massachusetts police detective Matthew Farwell was convicted of murdering Sandra Birchmore, a pregnant woman who had accused him of sexually abusing her as a minor, with the killing staged to look like a suicide.
• Birchmore, 23 at the time of her death in 2021, had a tumultuous relationship with Farwell dating back to her childhood involvement in a police youth program; the FBI later determined her death was a homicide after initial police investigations ruled it a suicide.
• The federal trial revealed that local police investigations were rushed and compromised, with critical evidence mishandled and Farwell inadequately questioned, leading to federal prosecutors criticizing the initial probe for protecting Farwell.
• Text messages uncovered by the FBI showed a sexual relationship beginning when Birchmore was 15, below the age of consent in Massachusetts, and escalating conflicts over pregnancy and Farwell's involvement with the unborn child.
• Farwell was sentenced to mandatory life imprisonment following a monthlong federal trial featuring extensive witness testimony and forensic evidence indicating Birchmore was strangled, though the defense contested the homicide findings.
