Boston Marathon suspect's friend due in court on gun, drug charges
{{#rendered}} {{/rendered}}A man authorities suspect provided the gun used by the Boston Marathon bombing suspects to kill an MIT police officer is due in federal court Wednesday for a court update.
Stephen Silva, of Cambridge, Massachusetts, is charged with heroin trafficking and possession of a handgun with an obliterated serial number.
Silva's indictment doesn't mention the slaying of MIT officer Sean Collier or bombing suspects Dzhokhar (joh-HAHR') and Tamerlan Tsarnaev (TAM'-ehr-luhn tsahr-NEYE'-ehv). It says Silva received a Ruger pistol in February 2013.
{{#rendered}} {{/rendered}}Two people with knowledge of the investigation who requested anonymity because they weren't authorized to discuss the investigation told The Associated Press the gun was used to kill Collier during a manhunt for the Tsarnaevs. Police recovered the Ruger after a shootout in which Tamerlan Tsarnaev was killed.
Silva was a friend of Dzhokhar's.
