The Florida man questioned by authorities for his connection to suspected Boston Marathon bomber Tamerlan Tsarnaev allegedly confessed to being involved with a 2011 triple murder before being fatally shot Tuesday by an FBI agent, NBC News reported.
Ibragim Todashev, 27, reportedly grew violent when he was on the verge of signing a written confession to playing a role in the grisly homicide that took place in a Waltham, Mass. apartment two years ago. Tsarnaev, who was killed in a shootout with police last month, was the roommate of one of the three victims in that murder, which has gone unsolved, and authorities began investigating his possible role in the slaying following the marathon bombings.
Investigators said that Todashev attacked the agent with a knife while being questioned in his Orlando, Fla. apartment.
