A former mixed martial arts fighter who was fatally shot by an FBI agent in Florida following a "violent confrontation" knew one of the Boston Marathon bombers and was being questioned about an unsolved triple homicide that may be linked to him, according to reports.
Ibragim Todashev, who was shot and killed early Wednesday during a shooting at an apartment complex near Universal Studios in Orlando, knew Tamerlan Tsarnaev, the older of the two brothers behind the April 15 bombing attack.
