ORLANDO, Fla. (AP) — The American Civil Liberties Union is asking state investigators in Florida and Massachusetts to look into the death of a Chechen man who was fatally shot while being questioned about his ties to one of the Boston Marathon bombing suspects.

The ACLU in both states on Monday called on the Massachusetts' attorney general and the Florida Law Department of Law Enforcement to investigate the roles of Massachusetts state troopers and Orlando police officers in Ibragim Todashev's (IH'-bruh-heem TOH'-duh-shehv's) death.

Todashev was killed in May while being questioned by FBI agents, Massachusetts state troopers and others.

Officials originally said Todashev had lunged at an FBI agent with a knife. They later said it was no longer clear what happened.

An investigation is being led by the FBI.
