Man who gave suspects gun identified
Federal prosecutors file charges against a Cambridge, Massachusetts man saying he supplied the gun to the Tsarnaev brothers that was used to kill MIT police offer Sean Collier three days after the bombing. Drug and firearms charges filed against Stephen Silva last week are made public. The indictment states he had a Ruger model 95 9mm pistol with the serial number obliterated as of February 2013; this is the same kind of gun was used to kill Collier.
