An anonymous reader writes: The Federal Bureau of Investigation says it is no longer investigating the unsolved mystery of D.B. Cooper. The bureau said Tuesday that it’s “exhaustively reviewed all credible leads” during its 45-year investigation and has redirected those resources to other priorities. The investigation was of a man calling himself Dan Cooper (the media mistakenly called him D.B. Cooper and it stuck) who hijacked a Boeing 727 headed for Seattle after boarding at Portland International Airport on November 24, 1971. In Seattle, he claimed he had an explosive device and demanded parachutes and $200,000 in ransom money. After releasing the 36 passengers from the plane and receiving four parachutes and $200,000 in cash, Cooper ordered several of the crew members who were kept on board to fly to Mexico City. Shortly after returning to the air, Cooper jumped from the back of the plane and landed somewhere in the Pacific Northwest. No trace of Cooper was found, but several bundles of cash were found in 1980. The FBI says it has conducted searches, collected all available evidence and interviewed all identifiable witnesses, but none have resulted in identifying the hijacker.
