ORLANDO, Fla. - A Chechen immigrant was shot to death by authorities in central Florida early Wednesday after he turned violent while being questioned about his ties to one of the Boston Marathon bombing suspects, officials said.
Ibragim Todashev, a 27-year-old mixed martial arts fighter, was fatally shot at his Orlando townhouse during a meeting with an FBI agent and two Massachusetts state troopers, authorities said. The agent was taken to a hospital with injuries that were not life-threatening.
Three law enforcement officials, speaking on condition of anonymity, said Todashev had lunged at the FBI agent with a knife. However, two of those officials said later in the day it was no longer clear what had happened. The third official had not received any new information.
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. However, two officials briefed on the investigation said he had implicated himself as having been involved in a 2011 triple-slaying in the Boston suburb of Waltham that authorities believe may have been connected to one of the men behind the bombings.
Several of Todashev's former roommates who were questioned said that he knew the older bombing suspect, 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. He's also charged in the slaying of an MIT police officer days later.
Investigators have been trying to establish the scope of the Boston bombings plot. Authorities in Massachusetts said they would investigate whether Tamerlan Tsarnaev had any connection to the unsolved 2011 deaths in Waltham, where three men were found 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.
