(Seattle, WA)  --  The mysterious case of D.B. Cooper is closed.  That's the word from the FBI on the case involving the 1971 hijacking of a Boeing jet from Portland to Seattle.  An FBI spokesperson says the bureau has redirected resources allocated to the D.B. Cooper case "in order to focus on other investigative priorities."  Investigators believe the man who called himself D.B. Cooper parachuted from the plane over Lake Merwin near Ariel, Washington with 200-thousand dollars in ransom money, but neither the suspect nor the money has ever been found.
