One of the country's most notorious unsolved crimes may have a comic book connection and while it may sound kooky, the FBI agent in charge of the case says the new clue is no laughing matter.
At Seattle-Tacoma International Airport, he released the passengers in exchange for $200,000 and four parachutes and asked to be flown to Mexico. He jumped from the plane somewhere near the Oregon state border.
The Dan Cooper comic book was popular in France in the 1960s and early 1970s and one issue published around the time of the hijacking shows the character parachuting.
Carr said this is an important clue in the case, because the comic books were never translated into English, which supports his theory that the hijacker had been in the Air Force and probably spent time in Europe, where he likely came across the Dan Cooper comic books.
