ORLANDO, Fla. (AP) -- Officials say the man who was shot to death by authorities in Orlando, Fla., this morning was a Chechen immigrant who was being questioned about his ties to one of the Boston Marathon bombing suspects.
They say Ibragim Todashev was shot and killed at his Orlando home after he lunged at an FBI agent with a knife. They say he was being questioned by the agent and two Massachusetts state troopers.
The agent was taken to a hospital with injuries that were not life-threatening.
The FBI isn't giving any details on why it was interested in Todashev. But some of his former roommates said Todashev knew one of the Boston bombing suspects, Tamerlan Tsarnaev, from mixed martial arts fighting in Boston, and that the FBI was asking about him.
Tamerlan Tsarnaev, the older of the two brothers suspected in the bombings, was killed after a shootout with police in the days following the attack. His younger brother, Dzhokhar, survived and is charged with carrying out the bombings.
Investigators have been trying to establish whether a wider plot was involved.
