Officials say a Chechen immigrant who was being questioned about his ties to one of the Boston Marathon bombing suspects was shot to death after a violent confrontation with an FBI agent.
Three law enforcement officials, speaking on condition of anonymity, said earlier Wednesday that Ibragim Todashev lunged at the FBI agent with a knife before he was shot. However, two of those officials said later that was no longer clear. The third had not received any new information since earlier in the day.
Police in Boston have released a new photo showing the man believed to be a suspect in the marathon bombings.
In the new photo, he's wearing a gray hoodie sweatshirt pulled up on his head. The photo was taken at a 7-Eleven in Cambridge, just across the river from Boston.
AP sources identify the man as 19-year-old Dzhokhar A. Tsarnaev of Cambridge, Massachusetts. He is the bombing suspect who is still alive. The other bombing suspect was killed overnight in an exchange of gunfire with police.
