Dead Boston bombing suspect Tamerlan Tsarnaev linked to triple murder ORLANDO, Fla., May 23 (UPI) -- The dead Boston Marathon bombing suspect is now tied to a triple murder, officials said after an alleged accomplice was gunned down by an agent questioning him. Tamerlan Tsarnaev was fingered by Ibragim Todashev in Orlando, Fla., in a 2011 Waltham, Mass., murder in which three people had their throats slashed, federal law enforcement officials told several news outlets. Todashev also implicated himself in the murders Wednesday -- moments before he was fatally shot by an FBI agent after he allegedly tried to assault the agent, two senior law enforcement officials said. "He used some kind of weapon" that prompted the agent to shoot, an official told CNN. Todashev had been talking in his apartment to the FBI and Massachusetts State Police about the Sept. 11, 2011, Waltham murders when "he exploded and leapt" at the agent, an official told The New York Times. The FBI agent sustained minor injuries that required stitches, the official said. Other law enforcement officials said the shooting occurred after 27-year-old Todashev admitted his role and implicated Tsarnaev. One official said Todashev began writing out a statement when he asked to take a break, the Times said. The FBI said it was reviewing the incident. Massachusetts' Middlesex District Attorney's Office, which is overseeing the homicide investigation, and Massachusetts police declined to comment. The three people killed Sept. 11, 2011, were Brendan Mess, 25, Erik Weissman, 31, and Raphael Teken, 37. Their bodies were found in an apartment a day later, covered in marijuana and cash. Tsarnaev, 26, and his younger brother, Dzhokhar, are accused of committing the April 15 Boston Marathon bombings that killed three people and injured more than 260. Dzhokhar Tsarnaev, 19, has been charged but hasn't entered a plea.
