Born into a Mormon family in Utah, Robert Leroy Parker grew up dirt poor and soon discovered that stealing horses and cattle was a fact of life in a world where small ranchers were being squeezed by banks, railroads, and cattle barons. A charismatic and more than capable cowboy—even ranch owners who knew he was a rustler said they would hire him again—he adopted the alias “Butch Cassidy,” and moved on to a new moneymaking endeavor: bank robbery. By all accounts a smart and considerate thief, Butch and his "Wid Bunch" gang eventually graduated to more lucrative train robberies. But the railroad owners hired the Pinkerton Agency, whose detectives pursued Butch and his gang relentlessly, until he and his then partner Harry Longabaugh (The Sundance Kid) fled to South America, where they replicated the cycle of ranching, rustling, and robbery until they met their end in Bolivia.
