ORLANDO, Fla. (AP) - A Chechen immigrant who was being questioned about his ties to one of the Boston Marathon bombing suspects was shot to death early Wednesday after he lunged at an FBI agent with a knife, officials said.
Ibragim Todashev, a 27-year-old mixed martial arts fighter, was gunned down by authorities at his Orlando home during a meeting with the agent and two Massachusetts state troopers, authorities said. The agent was taken to a hospital with injuries that were not life-threatening.
The FBI gave no details on why it was interested in Todashev except to say that he was being questioned as part of the Boston investigation.
But some of his former roommates who were questioned as well said that Todashev knew one of the bombing suspects, Tamerlan Tsarnaev, from mixed martial arts fighting in Boston and that the FBI was asking about him.
Public records show Todashev lived in Watertown, Mass., just outside Boston, last year.
Tamerlan Tsarnaev, an aspiring boxer, was killed in a shootout with police days after the April 15 bombings. His younger brother, Dzhokhar, survived and is charged with carrying out the attack that killed three people and wounded more than 260.
Investigators have been trying to establish the scope of the plot. In addition, authorities in Massachusetts said they would investigate whether Tamerlan Tsarnaev had any connection to an unsolved 2011 slaying in the Boston suburb of Waltham, where three men were found dead in an apartment, their throats slit and marijuana sprinkled over their bodies. One of the victims was a boxer and a friend of Tsarnaev's.
Todashev had lived on and off with other Chechens in the Orlando suburb of Kissimmee and had moved to Orlando more recently, friends said.
Police records suggest he had a hot temper, with arrests in a road-rage incident and, more recently, in a fight over a parking space.
Former roommate Khusen Taramov said the FBI was asking questions about a conversation Todashev had with the elder bombing suspect a month before the Boston Marathon attack.
Two law enforcement officials, speaking on condition of anonymity because they were not authorized to release details of the investigation, said Todashev came at the FBI agent with a knife before he was shot.
An FBI team was dispatched from Washington to review the shooting, standard procedure in such cases.
