A Chechen man who was fatally shot by an FBI agent last week during an interview about one of the Boston bombing suspects was unarmed, law enforcement officials said Wednesday. …

In the statement about Todashev’s shooting issued on the day of the incident, the FBI said that an agent, along with two Massachusetts State Police troopers and other law enforcement personnel, were interviewing “an individual” in connection with the Boston Marathon bombing investigation when a “violent confrontation was initiated by the individual.” …

Initial reports citing anonymous law-enforcement individuals provided conflicting accounts of what happened. Some law enforcement officials said Todashev wielded a knife and others suggested that he attempted to grab the FBI agent’s gun.

One law enforcement official, speaking on the condition of anonymity to discuss an ongoing investigation, said Wednesday that Todashev lunged at the agent and overturned a table. But the official said Todashev did not have a gun or a knife. A second official also said Todashev was unarmed.
