ORLANDO, Fla. — A Florida prosecutor is preparing to announce the results of his investigation into an FBI agent’s fatal shooting of a Chechen man as he was being questioned about a Boston Marathon bombing suspect.

State Attorney Jeff Ashton said in a statement Thursday that he plans to release his report on Tuesday morning.

Ibragim Todashev was killed in Orlando in May while FBI agents and others questioned him about his friendship with suspected Boston Marathon bomber Tamerlan Tsarnaev. Officials originally said the 27-year-old lunged at an agent with a knife. They later said it was no longer clear what happened.

Ashton met with Todashev’s family in August and shortly after that he said he would review the circumstances that led to the shooting.
