Feds: Man Who Gave Boston Marathon Bombing Suspects Gun That Killed MIT Officer Arrested

Federal prosecutors have filed charges against a Cambridge man who law enforcement authorities say gave the Boston Marathon bombing suspects the gun that was used to kill Massachusetts Institute of Technology Police Officer Sean Collier four days after the attacks on Boylston Street, reported NECN.

Stephen Silva, 21, had drug and firearms charges filed against him last week, but they were made public Tuesday, July 22.

NECN reports:

Although the federal indictment does not mention the Collier shooting or the Tsarnaevs, law enforcement officials say Silva was the source of the gun used to kill Officer Collier. The federal indictment says Silva’s Ruger model 95 9mm pistol was the same kind of gun was used to kill Collier, federal officials have previously said.

Silva was also accused of distributing heroin, according to charges (which you can read in full here) that were unsealed July 22.

The Boston Globe reports:

According to federal documents, Silva, around February 2013 in Cambridge, two months before the bombing, “knowingly received and possessed a firearm, to wit: A Ruger model P95 9mm pistol, which had the importer’s and manufacturer’s serial number removed, obliterated and altered and had previously been shipped and transported in interstate and foreign commerce.”

The Globe also reports that Silva was close friends with Dzhokhar Tsarnaev, and was a classmate at Cambridge Rindge and Latin. His twin brother was reportedly even closer with Tsarnaev, since the pair attended high school and UMass-Dartmouth together.

Silva’s next court hearing is scheduled for August 6.
