Medical examiner Maria Capo Martinez testified that evidence in the death of 23-year-old Sandra Birchmore indicates her body may have been moved. Matthew Farwell is currently on trial for the murder of Birchmore, who was found dead in Canton in 2021.

Why it matters

The testimony challenges previous conclusions about the death, which was initially ruled a suicide before the medical examiner updated the death certificate to undetermined. Federal investigators now contend that evidence points to a homicide rather than self-inflicted harm.

Medical examiner Maria Capo Martinez changed the official cause of death on the death certificate from suicide to undetermined following an FBI investigation. The trial in Boston continues with testimony regarding discrepancies in the scene report.
