SEATTLE -- The FBI is investigating its most promising new lead in decades in the D.B. Cooper case, the nation's only unsolved commercial hijacking, a Seattle paper reported Saturday.
According to The Seattle Post-Intelligencer, the lead is focused on a man not previously associated with the 1971 case.
An item belonging to the man was being analyzed at the FBI forensic lab in Quantico, Virginia, according to the report.
The FBI did not say what sort of item it was, but did say agents were unsure whether fingerprints could be be pulled from it. They also did not release the man's name.
DNA samples from the item will be compared to a tie clip left behind on the hijacked plane. The suspect jumped from the plane and was never found. Some agents believe he was killed.
A boarding pass with the name Dan Cooper on it was found, as was a discarded parachute. But most of the money the suspect stole the night he hijacked the plane was never recovered.
