Man Who Loaned Gun to Tsarnaev to Be Sentenced Tuesday

Stephen Silva, the man who loaned his gun to Boston Marathon Bomber Dzhokhar Tsarnaev, which was used to kill Wilmington native Sean Collier, is expected to be sentenced Tuesday in U.S. District Court.

Collier was living in Somerville at the time of his murder and was due to be sworn in as a police officer before his death. Collier was posthumously sworn in as a Somerville Police officer four months after he was killed.

Silva initially pleaded innocent after being charged in July 2014, before changing his plea last December. He was charged with possession of a handgun with an obliterated serial number and seven counts of heroin trafficking, according to WHDH, 7-News.

The Associated Press is reporting Silva Tsarnaev borrowed the Ruger 9mm two months before the bombings after he said Tsarnaev told him he wanted to rob students at the University of Rhode Island.

Collier was killed four days after the Boston Marathon bombings when he was ambushed in his police cruiser by two men who were the center of the manhunt that terrorized the state and the region, killing four and injuring more than 170 others.
