William Gossett was a veteran of the Korean and Vietnam wars, as well as a skilled parachutist and survivalist. After the DB Cooper case became public, Gossett was obsessed and told his sons and a San Diego judge that he was the mystery man behind the hijacking. According to William's son, Greg Gosset, William was constantly strapped for cash but had wads of money to spend just before Christmas 1971 — weeks after the skyjacking. Despite William's claims, investigators could not find any evidence incriminating the veteran. He died of natural causes in 2003 at the age of 73.
