Butch Cassidy Butch Cassidy Robert Leroy Parker (April 13, 1866 – November 7, 1908), better known as Butch Cassidy, was a notorious American train robber and bank robber, and the leader of a gang of criminal outlaws known as the "Wild Bunch" in the American Old West. After participating in criminal activity in the United States for more than a decade at the end of the 19th century, the pressures of being pursued by law enforcement, notably by the Pinkerton detective agency, forced Parker to flee the country with an accomplice, Harry Alonzo Longabaugh, known as the "Sundance Kid", and Longabaugh's girlfriend
Butch Cassidy entered the house the next morning, whereupon they found two bodies, both with numerous bullet wounds to the arms and legs. The man assumed to be Longabaugh had a bullet wound in the forehead and the man thought to be Cassidy had a bullet hole in the temple. The local police report speculated that, judging from the positions of the bodies, Cassidy had probably shot the fatally wounded Longabaugh to put him out of his misery, just before killing himself. In the following investigation by the Tupiza police, the bandits were identified as the men who robbed the Aramayo payroll
