U.S. news reports say a Chechen man killed in an altercation with an FBI agent implicated himself in a triple slaying that may have been connected to dead Boston Marathon bombing suspect Tamerlan Tsarnaev.
The FBI says Ibragim Todashev was fatally shot Wednesday in Orlando, in the southeastern U.S. state of Florida when he attacked an FBI agent with a knife during questioning in the Boston Marathon bombings probe.
Todashev formerly lived in the Boston area and trained in martial arts at a gym with Tsarnaev.
Officials, who asked not to be identified, said Todashev implicated himself and Tsarnaev in the 2011 killing of three men, including one who trained at the same gym.
Police records indicate Todashev had been arrested in the past in a Boston road-rage incident and, more recently, he was awaiting trial in an Orlando fight over a parking space.
Todashev and Tsarnaev were both ethnic-Chechen immigrants with U.S. resident status.
Tamerlan Tsarnaev was killed in a shootout with police a few days after the bombings. His younger brother, Dzhokhar, is in federal custody on charges he helped in the twin blasts that killed three people and injured 264 others April 15 during the Boston Marathon.
