The top prosecutor in Orlando says he will review the circumstances that led to the fatal shooting of a Chechen immigrant during questioning by the FBI and other agents in Orlando about his ties to one of the Boston Marathon bombing suspects.

State Attorney Jeff Ashton said Thursday that he has received a preliminary report by the federal Department of Justice about their investigation into Ibragim Todashev's death last May.

Ashton says there is no schedule for when he will complete his review.

Below is his full statement:

The Office of the State Attorney is in receipt of the preliminary investigation from the Department of Justice in regards to the death of Ibragim Todashev. Pursuant to his previously announced policy, Mr. Ashton will conduct an independent review of the circumstances surrounding the use of deadly force in this case, as he does in all cases involving use of force by a law enforcement officer resulting in death. There is no timetable as to when he will complete his review. There will be no further public comment regarding this matter until the State Attorney’s review is completed.

Todashev was killed while being questioned by FBI agents and police from Massachusetts and Florida. Officials originally said Todashev lunged at an FBI agent with a knife. They later said it was no longer clear what happened.

An investigation was being led by the FBI.
