Ex-Cop Accused of Murder to Hide Teen Affair

Closing arguments are imminent in the trial of Matthew Farwell, a former Massachusetts police officer accused of killing Sandra Birchmore, 23, in 2021. Prosecutors allege Farwell murdered Birchmore to conceal their relationship, which began when she was 15. He is accused of staging her death to appear as a suicide.

Birchmore was found deceased in her apartment with a strap around her neck. Local police and the Massachusetts State Police, influenced by personal ties to Farwell, quickly concluded she died by suicide. The state medical examiner's office initially concurred, but has since revised the cause of death to 'undetermined'.

Friends and family of Birchmore never believed she took her own life. She had shared news of her pregnancy with dozens of friends and was preparing for motherhood, having booked a maternity shoot and planned a baby shower. Her apartment contained baby supplies and an ultrasound photo.

The FBI's investigation, initiated in 2023, critiqued the local probe as rushed and compromised. Investigators noted Farwell's brief interview and lack of thorough examination. Text messages uncovered by the FBI revealed intimate exchanges from when Birchmore was 15, and escalating tensions as she pressured Farwell about the pregnancy.

Forensic experts presented conflicting findings regarding Birchmore's cause of death, with prosecution experts suggesting strangulation and defense experts arguing for suicide by hanging. Farwell's defense claims he visited Birchmore to end their relationship and that she died by suicide due to financial struggles and mental health challenges.

Crucially, a paternity test later determined that another man was the father of Birchmore's unborn child. The defense highlighted Birchmore's history of mental health issues, including psychiatric medication use since age 6 and past suicide attempts.
