BOSTON — Former Stoughton Police officer Matthew Farwell was found guilty of killing Sandra Birchmore and causing the death of her unborn child.
The jury of eight men and four women in his federal murder trial returned their verdict Tuesday on their third day of deliberations.
Federal prosecutors had argued that Farwell murdered Birchmore in her Canton apartment in February 2021, then staged her body to make it a suicide.
They charged the defendant with killing a witness, contending that he killed the 23-year-old to cover up other crimes, including that he’d started a relationship with the victim when she was 15 years old.
His charges come with a mandatory life sentence after prosecutors opted not to go for the death penalty, which is an option in federal capital cases.
