Duane Weber was one of the many men to confess to being Cooper on his deathbed. According to his wife, Jo, he frequently had nightmares about leaving fingerprints on a plane, and he had a knee injury he claimed to have received from jumping out of a plane. He also had an old Northwest airline ticket and had previously taken Jo to the area where the $5,800 would later be found. Despite all this, the FBI doesn’t believe him to be Cooper.
