By Defendant allegedly murdered a pregnant young woman and staged her death to look like a suicide to prevent law enforcement from learning about their sexual relationship which began when she was a minor
BOSTON – A former Stoughton, Mass. police officer has been charged in federal court in Boston with allegedly murdering a young woman to prevent her from disclosing information about his longstanding sexual exploitation of her while he was on duty, beginning when she was a minor.
Matthew Farwell, 38, of North Easton, Mass., has been indicted on one count of killing a witness or victim. Farwell was arrested this morning and will make an initial appearance in federal court in Boston at 2:30 p.m. today.
According to the indictment, on or about Feb. 1, 2021, Farwell allegedly killed Sandra Birchmore by strangulation. It is alleged that Farwell staged her body and apartment to make it appear as if Birchmore had committed suicide.
The indictment alleges that Farwell killed Birchmore with the intent to prevent law enforcement from learning about Farwell’s commission or possible commission of federal offenses.
According to court documents, Farwell was a sworn officer of the Stoughton Police Department beginning on or about March 27, 2012, until on or about April 1, 2022.
In his capacity as a police officer, Farwell served as an instructor for the Stoughton Police Department’s Explorer’s Program, which is a vocational education program designed for youth to learn about careers in law enforcement.
Sandra Birchmore joined the Stoughton Explorers Program in 2010, when she was 12 years old. Farwell allegedly used his authority and access to groom, sexually exploit and ultimately sexually abuse Birchmore when she was 15 years old and continued to have sex with her when she became an adult.
On several occasions, Farwell allegedly engaged in sex acts with Birchmore while on duty as a Stoughton police officer. To conceal this activity, it is alleged that Farwell falsely represented that he had worked certain hours, when in fact he was not working but engaging in sex acts with the then-minor victim. Farwell’s sexual contact with Birchmore continued until her death on Feb. 1, 2021.
In December 2020, Birchmore learned that she was pregnant. According to court documents, she was excited about the pregnancy: scheduling doctors’ appointments, purchasing items for childcare and telling loved ones how happy she was to become a mother.
Soon after she learned she was pregnant, Birchmore told Farwell that he was the father of the child and that she expected him to be involved, at least in part, in the child’s life.
Birchmore disclosed to loved ones that Farwell allegedly became violent with her when they discussed the pregnancy and his role in the child’s life. At one point while she was pregnant, Farwell allegedly held Birchmore in a headlock and told her that he wished she were dead.
On or about Jan. 20, 2021, Birchmore’s friend called the Stoughton Police Department and referenced Farwell and Birchmore’s sexual relationship. Upon learning this, Farwell allegedly then sent Birchmore angry text messages and, a few days later – approximately one week prior to Birchmore’s death – Farwell visited Birchmore at her apartment in Canton and asked her if she could give him a spare apartment key and keep it a secret.
It is further alleged that one week prior to her death, Farwell visited Birchmore’s apartment and began looking through her closets and bathroom, conduct which made her uncomfortable.
The court documents allege that, on Feb. 1, 2021, facing perceived imminent disclosure of his criminal conduct, Farwell murdered Birchmore to silence her.
According to court documents, while Birchmore’s death was initially ruled a suicide, the federal investigation probed old evidence and revealed critical new evidence leading to the charge against Farwell.
The charge of killing a witness or victim carries a mandatory sentence of death or life in prison. Sentences are imposed by a federal district court judge based upon the U.S. Sentencing Guidelines and statutes which govern the determination of a sentence in a criminal case.
Acting United States Attorney Joshua S. Levy and Jodi Cohen, Special Agent in Charge of the Federal Bureau of Investigation, Boston Division made the announcement today.
The Massachusetts Attorney General’s Office, Massachusetts State Police, Stoughton Police Department and Norfolk District Attorney’s Office provided assistance in the investigation. Assistant U.S. Attorneys Elizabeth Riley, Torey B. Cummings and Brian A. Fogerty of the office’s Human Trafficking & Civil Rights Unit are prosecuting the case.
The details contained in the charging documents are allegations. The defendant is presumed innocent unless and until proven guilty beyond a reasonable doubt in a court of law.
