ORLANDO, Fla. - A Chechen immigrant shot to death in Florida after an altercation with an FBI agent implicated himself in a triple slaying that officials believe may have been connected to Boston Marathon bombing suspect Tamerlan Tsarnaev, authorities said.

Three law enforcement officials, speaking on condition of anonymity, said initially that Todashev had lunged at the FBI agent with a knife.

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.
