WASHINGTON (AP) — A Florida prosecutor has cleared an FBI agent of any criminal wrongdoing in the fatal shooting of a Chechen man as he was being questioned about a Boston Marathon bombing suspect, two law enforcement officials with knowledge of the investigation said Friday.

The officials, speaking on condition of anonymity Friday because they weren’t authorized to speak publicly about the case, said State Attorney Jeff Ashton won’t bring charges against the agent who shot Ibragim Todashev, a 27-year-old mixed martial arts fighter.
