Kid Curry was not successful in much of anything without Cassidy's help. The Parachute robbery was no exception. In fact, it ended his career as the cold blooded killer of the Wild Bunch. He and his two pals were chased by the law into the mountains where Kid Curry was killed in a gun fight.
Of course there are those who say the man killed was not him but the family in Colorado at Sand Creek never heard from him again. That is the same family that passed the Kid Curry story down to Bruce Lamb who wrote the book about his family and their involvement with Kid Curry. If you get the chance, read that book. It is very interesting.
