Overview
- Prosecutors resumed key FBI testimony on Monday, Oct. 19, 2026, presenting tens of thousands of messages and phone‑forensic data to support their claim that Matthew Farwell groomed and sexually exploited Sandra Birchmore beginning when she was a minor.
- FBI Special Agent Heidi Kelsch read explicit texts in court and digital examiners described recovered records, including a baby‑name list on Birchmore’s phone and post‑incident searches on Farwell’s device about consent and recovering deleted iMessages.
- Surveillance video and cellphone records introduced at trial place Farwell entering and leaving Birchmore’s apartment building on the night she died and show her phone’s last movements and unlock times close to that period.
- Forensic evidence presented includes warrants that led investigators to collect Farwell’s DNA, which prosecutors say matched material from a ligature and clothing while DNA testing excluded him as the fetus’s father; the defense continues to argue suicide and cites Birchmore’s mental‑health history.
- The case rests on uncommon federal theories that would require proving Farwell killed to stop reporting of alleged federal crimes, and the trial follows an internal affairs review of the Stoughton Police Department that prompted resignations and a federal takeover of the probe.
