Unsolved: D.B. Cooper
Since 1971, the Federal Bureau of Investigation (FBI) has been on the trail of notorious hijacker D.B. Cooper, but this summer the agency announced that it was closing the books on the Cooper case, instead choosing to shift resources to "other investigative priorities."
"During the course of the 45-year NORJAK investigation, the FBI exhaustively reviewed all credible leads, coordinated between multiple field offices to conduct searches, collected all available evidence, and interviewed all identified witnesses," an FBI statement released in July read. "Over the years, the FBI has applied numerous new and innovative investigative techniques, as well as examined countless items at the FBI Laboratory."
"In order to solve a case, the FBI must prove culpability beyond a reasonable doubt, and, unfortunately, none of the well-meaning tips or applications of new investigative technology have yielded the necessary proof," the statement continues.
Evidence related to the Cooper case will be archived, and should new information or evidence emerge, specifically the parachutes used or money taken by the hijicker, the FBI will reopen the case.
