The FBI on Monday announced it will no longer be investigating one of the most mysterious hijacking crimes in the history of the bureau.
After 45 years of investigating with no results, the FBI has decided to finally give up on finding D.B. Cooper, who parachuted out of a hijacked plane with $200,000 in 1971, the New York Daily News reported on Tuesday.
D.B. Cooper, whose true identity is still not known, boarded a Northwest Airlines flight from Portland, Ore., to Seattle on Nov. 24, 1971. During the flight, Cooper, who was wearing a black suit and tie, showed the flight attendant a bomb in his suitcase.
After the plane landed in Seattle, Cooper demanded $200,000 in cash and several parachutes before releasing the passengers and asking that the plane take him to Mexico.
However, 45 minutes into the flight, Cooper parachuted out of the airplane, with the bag of cash strapped to his body.
Besides clues such as decayed stacks of cash and some articles of clothing, the investigators have not been able to find anything else on D.B. Cooper, who effectively pulled off a perfect crime.
