Testimony in the federal trial of Matthew Farwell, a former Stoughton police detective, continued this week with jurors hearing from witnesses including the state's chief medical examiner, Dr. Maria Del Mar Capo Martinez, and William 'Billy' Farwell, Matthew's twin brother. Matthew Farwell is accused of killing Sandra Birchmore, a 23-year-old woman who was pregnant, in 2021 and staging her death as a suicide. Prosecutors allege he had a sexual relationship with Birchmore when she was 15 and killed her to prevent her from exposing his abuse. Billy Farwell testified he had also had a sexual relationship with Birchmore and that she told him she was pregnant with his brother's child, though DNA later excluded Matthew Farwell as the father.
Dr. Capo Martinez initially ruled Birchmore's death a suicide by asphyxia by hanging but changed the manner to 'undetermined' in 2026 after learning more about the case.
