Unraveling the D.B. Cooper Mystery: Eric Ulis's Investigation

Eric Ulis, a self-proclaimed crime historian and aviation geek, is suing the FBI for access to a clip-on necktie left behind by the mysterious hijacker known as D.B. Cooper. Ulis believes that the tie knot may contain undiscovered DNA that could help unravel Cooper's identity. He hopes to collect swabs from the tie's metal spindle and enter any DNA found into genealogy databases. Ulis has dedicated years to investigating the unsolved 1971 hijacking case and has organized events like CooperCon. Despite the FBI closing the case in 2016, Ulis remains determined to find out who Cooper was and believes the truth is within reach.
