The FBI is investigating a "credible" lead in the "D.B. Cooper" skyjacking case in which a man hijacked a plane for $200,000 in ransom in 1971 and parachuted into the night with the bag full of cash, the Seattle Times reports.

She says the FBI, responding to a tip, is trying to extract a fingerprint from an item linked to a potential suspect and compare it to one taken from the Boeing 727 after the Thanksgiving Eve skyjacking.
She calls the new information "the most promising lead we have right now," the Times reports.
In the hijacking, "Cooper" claimed to have a bomb and forced the plane to Northwest Orient flight to land, where he obtained parachutes and the ransom money. He bailed out somewhere northwest of Portland.
Some of the money was found by a child digging in a sandbar along the Columbia River in 1980, but the whereabouts of "Cooper" remains a mystery, assuming that he survived the jump from 10,000 feet.
