DEDHAM, Mass. — Former Stoughton police officer Matthew Farwell, who stands accused of killing a pregnant woman, is now also charged in connection with the death of her unborn child.
Farwell was arrested and indicted on a federal charge of killing a witness or victim in August 2024 in the 2021 death of 23-year-old Sandra Birchmore. A superseding indictment filed on Tuesday revealed that the disgraced officer has additionally been charged with violation of the protection of an unborn child.
Court documents obtained by Boston 25 News allege Farwell “caused the death of a child in utero” on or around Feb. 1, 2021, in Canton.
Prosecutors allege Farwell murdered Birchmore after she informed him he was the father of her unborn child. He was also a married father of three at the time.
Farwell was one of three Stoughton officers who had an inappropriate relationship with Birchmore when she was a young teen in the Stoughton Police Department’s Explorers Program, according to investigators. It’s alleged that Farwell had engaged in sexual intercourse with Birchmore before she was 16 years of age.
Birchmore’s death was originally ruled a suicide when she was found hanging in her Canton apartment in February 2021. But last year, police announced there was evidence Sandra was killed.
Farwell is accused of staging Birchmore’s death to make it look like she had hung herself.
Because of the federal charges, prosecutors could seek the death penalty against Farwell.
The judge presiding over the case recently scheduled the start of Farwell’s trial for Oct. 5, 2026.
