ORLANDO, Fla. (CBS) — An FBI agent shot and killed a man after he implicated himself and the Boston Marathon bombings suspect, Tamerlan Tsarnaev, in an unsolved 2011 Waltham triple murder.

CBS News correspondent John Miller, a former FBI assistant director, says Ibrahim Todashev was “someone (the agency was) looking at in connection with Tamerlan (Tsarnaev), based on contacts they had.”
