A federal jury in Massachusetts is currently deliberating the case of Matthew Farwell, a former Stoughton police officer charged with the 2021 death of 23-year-old Sandra Birchmore. Prosecutors allege that Farwell strangled Birchmore in her apartment and staged the scene to appear as a suicide to prevent her from revealing years of sexual abuse. Farwell has pleaded not guilty to charges of killing a witness or victim and causing the death of an unborn child.
The case follows a 2021 investigation that initially classified Birchmore’s death as a suicide, a finding local authorities later changed to undetermined. Federal authorities brought charges against Farwell in 2024 following a separate investigation. During the trial in U.S. District Court in Boston, Farwell’s defense team acknowledged he had an affair with Birchmore but argued her death was a suicide, citing a 2017 journal entry and recent internet searches regarding suicide.
Evidence presented during the trial included surveillance footage showing Farwell entering Birchmore's building at 9:14 p.m. on February 1, 2021, and leaving at 9:43 p.m. Digital forensics showed Birchmore’s phone recorded its final steps at 9:40 p.m. While Birchmore believed Farwell was the father of her unborn child and allegedly used the pregnancy to pressure him to stay with her, DNA testing later revealed the father was Jason Pickard, a defense contractor Birchmore had also been seeing.
Medical experts offered conflicting testimony regarding the physical evidence found at the scene. Dr. William Smock, testifying for the prosecution, stated the fracture of Birchmore's hyoid bone and a specific chest injury suggested homicide and a staged scene. Conversely, defense experts, including Dr. Thomas Andrew, testified that the evidence was consistent with suicide and noted that the injuries did not definitively prove manual strangulation.
The scale of the case is centered on the single death of a 23-year-old woman in 2021 and the subsequent federal investigation that led to charges three years later. For the public and members of the Stoughton community, the trial highlights the testimony of a police dispatcher who claims a supervisor told him to "forget about" a call reporting the inappropriate relationship. This testimony raises questions about internal police accountability and the handling of reports involving fellow officers.
A person following this case would notice the impact on legal precedents regarding the classification of suspicious deaths and the use of digital forensic data, such as phone movement logs, in criminal trials. The case also involves the testimony of military personnel and school officials, showing how the investigation reached into multiple sectors of the community. A verdict will determine Farwell's legal future and whether the federal government has met the burden of proof to convict a former officer of witness tampering through murder. Jurors are currently deliberating in Boston, with a verdict expected following the conclusion of their discussions.
