A Chechen immigrant shot to death in central Florida early Wednesday after an altercation with an FBI agent shares a similar background to that of one of the Boston Marathon bombing suspects who authorities were questioning him about at the time.

Ibragim Todashev's Chechen roots and mixed martial arts background mirror that of Tamerlan Tsarnaev, the Boston bombing suspected killed in a shootout with police last month. The two also had lived in the Boston area.

Todashev was fatally shot Wednesday by authorities at his Orlando home during a meeting with the agent and two Massachusetts state troopers.

Two officials briefed on the investigation say Todashev had implicated himself as being involved in a 2011 triple-slaying in a Boston suburb that authorities believe may have been connected to Tamerlan Tsarnaev.
