Former Stoughton police officer Matthew Farwell has been ordered to remain in custody until his trial after a federal magistrate judge deemed him a risk to the community and a flight risk. The judge's decision, made on Tuesday, followed allegations that Farwell murdered 23-year-old Sandra Birchmore in her apartment in 2021, subsequently staging her death to appear as a suicide. While Farwell has pleaded not guilty, prosecutors presented strong evidence, including new data from his iPhone, which indicated his continued sexual interest in teenage girls, raising concerns about his potential danger to the community. The initial death certificate for Birchmore listed her cause of death as suicide, but it has since been amended to 'undetermined.' Farwell's defense team argued for his release, claiming that his behavior post-Birchmore's death indicated he was not a flight risk, and emphasized that he was not the father of her unborn child. The case continues to unfold as the trial date approaches.
