CHEYENNE, Wyo. (AP) -- Though most historians believe Old West outlaw Butch Cassidy died in a 1908 shootout in Bolivia, a Utah book collector says it's just possible that he survived and lived to old age in Washington state.
Brent Ashworth says he has obtained a manuscript with new evidence that may give credence to that theory.
He says "Bandit Invincible: The Story of Butch Cassidy," is twice as long as a previously known but unpublished novella of the same title by William T. Phillips, who died in Spokane in 1937.
Ashworth and Montana author Larry Pointer say the text contains the best evidence yet -- with details only Cassidy could have known -- that "Bandit Invincible" was not biography but autobiography, and that Phillips himself was the legendary outlaw.
But Cassidy historian Dan Buck isn't convinced. He says it "doesn't bear a great deal of relationship to Butch Cassidy's real life, or Butch Cassidy's life as we know it."
