The man killed by an FBI agent during questioning about his relationship with one of the Boston Marathon bombing suspects was unarmed when the agent shot him, law enforcement officials told the Washington Post.

Ibragim Todashev, 27, was interrogated for hours on May 22 in Orlando, Fla., regarding his connection with Tamerlan Tsarnaev, who died during a shootout with police days after the bombing.

Law enforcement officials initially told ABC News that, Todashev "just went crazy," brandishing a knife and stabbing the FBI agent.

An unnamed source contradicted that account, however, telling the Washington Post today that Todashev had no weapon. But Todashev did flip over the table and lunge at the FBI agent, the source said.
