Reni Manukyan, 24, told The Wall Street Journal FBI agents questioned her at her Atlanta home Tuesday at about the same time agents were questioning her late husband, Ibragim Todashev, at his home in Orlando, Fla. However, the newspaper reported Thursday, Manukyan said agents did not ask her about the Sept. 11, 2011, slaying of three men in Waltham, Mass., in which her late husband and dead marathon bombing suspect Tamerlan Tsarnaev have been implicated.
Instead, she said agents questioned her about Tsarnaev.
Tsarnaev was fingered by Ibragim Todashev in the three Waltham deaths, in which the victims' throats were slashed, federal law enforcement officials told several news outlets.
Todashev implicated himself in the slayings 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 Waltham killings when he "exploded" and attacked 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 Todashev, 27, 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.
The Middlesex (Mass.) District Attorney's Office, which is overseeing the homicide investigation, and Massachusetts police declined to comment.
The three people killed in Waltham 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 has not yet entered a plea.
