SEATTLE -- The FBI says it has a "credible" lead in the D.B. Cooper case, which involved the 1971 hijacking of a passenger jet over Washington state and the suspect's legendary parachute escape.
FBI spokeswoman Ayn Sandalo Dietrich tells The Seattle Times that a law enforcement member directed investigators to a person who might have helpful information on the suspect.
Dietrich says an item belonging to the man was sent to a lab in Quantico, Va., for forensic testing. She did not provide specifics about the item or the man's identity.
Federal investigators have checked more than 1,000 leads since a hijacker dubbed "D.B. Cooper" parachuted from a flight with $200,000 dollars in ransom.
His fate remains unknown, although the Seattle Post Intelligencer reports agents have previously said they believe he died the night he jumped.
