A "Lead" in Finding D.B. Cooper

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 told 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.
