"Sleuth's Lawsuit Demands FBI's DB Cooper Files to Unmask Iconic Plane Hijacker"

A citizen sleuth, Eric Ulis, has sued the FBI in an attempt to gain access to a black clip-on tie left behind by the iconic plane hijacker, DB Cooper, during the 1971 skyjacking. Ulis believes that the tie's metal spindle could contain undiscovered DNA that could help solve the case. The FBI has denied his FOIA request to lift a DNA sample from the garment, but Ulis argues that recent advances in ancestral genealogy could potentially identify Cooper's family members. Ulis also plans to continue searching for Cooper's still-lost parachutes and bag of cash, as he believes they may hold further clues.
