SEATTLE -- The FBI said Tuesday it is no longer investigating the enduring mystery of the skyjacker known as D.B. Cooper, nearly 45 years after he vanished out the back of a Boeing 727 into a freezing Northwest rain wearing a business suit, a parachute and a pack with $200,000 in cash.

Calling the investigation one of the longest and most exhaustive in the agency's history, the FBI Seattle field office said in an email it was time to focus on other cases. The agency said it will preserve evidence from the case at its Washington, D.C., headquarters, but it doesn't want further tips unless people find parachutes or Cooper's money.

"The mystery surrounding the hijacking of a Northwest Orient Airlines flight in November 1971 by a still-unknown individual resulted in significant international attention and a decades-long manhunt," the FBI said. "Although the FBI appreciated the immense number of tips provided by members of the public, none to date have resulted in a definitive identification of the hijacker."
