BOSTON (WWLP) – A Brookline man is being charged by criminal complaint with the unlawful possession of a machinegun and was detained on Friday.

Stewart Silvestri was arrested for firearms charges on October 15th after a Trooper was called to the weigh station on I-95 south in Rowley after witnesses reported a vehicle being operated erratically had pulled into the weigh station. The Trooper spoke with the driver of the 2018 Mitsubishi Outlander, 24-year-old Stewart Silvestri, and observed a handgun with a 50-round drum magazine in plain sight inside the vehicle and another handgun under the driver’s seat.

According to the charging document, a subsequent search of the vehicle recovered eight privately made firearms (also known as ghost guns), hundreds of rounds of ammunition and numerous firearm parts. Two of the firearms were fully automatic pistols, classified as machine guns. 

Silvestri faces up to 10 years in prison, three years of supervised release, and a fine of $250,000.

“The alleged conduct here is incredibly serious. Mr. Silvestri allegedly possessed eight unserialized and untraceable ghost guns. These dangerous weapons are nearly impossible to trace and directly contribute to the ongoing plague of gun violence we see across the nation and in our Commonwealth. Moreover, two of the firearms Mr. Silvestri allegedly possessed were machineguns capable of causing extreme harm, destruction and even mass casualties in the blink of an eye,” said United States Attorney Rachael S. Rollins. “Firearms, including ghost guns, are deadly weapons and those who illegally possess them are a potential threat to the safety of our neighborhoods. We will identify and prosecute these individuals and seek pre-trial detention whenever possible if it will result in keeping those that pose this type of danger off our streets.”

“The illegal possession of fully automatic “ghost guns” is a federal crime that ATF takes very seriously as it threatens the safety of our communities,” said James M. Ferguson, Special Agent in Charge of the Bureau of Alcohol, Tobacco, Firearms, and Explosives, Boston Field Division. “ATF will continue to work tirelessly with our local state and federal partners to investigate and arrest those who illegally possess firearms.”
