It’s one of the greatest unsolved mysteries in the FBI’s history, and now after three decades there’s a hot new lead.

In 1971, D.B. Cooper parachuted out of an airplane over the Pacific Northwest with $200,000 in ransom – and disappeared along with the money. The case has remained unsolved.

The FBI’s new lead came from a member of law enforcement, according to CNN. The information includes an item that was sent to a lab in Quantico, Va., for testing.

FBI spokeswoman Ayn Sandalo Dietrich tells the Seattle Times the information the “most promising lead we have right now,” but cautions agents are not on the verge of breaking the case.
