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 Railroad chairman E. H. Harriman attempted to meet with Cassidy through his old ally Matt Warner. On August 29, 1900, Cassidy, Longabaugh and others robbed Union Pacific train No. 3 near Tipton, Wyoming, violating Cassidy's earlier promise to the Governor of Wyoming and ending any chance for amnesty. On February 28, 1900, lawmen attempted to arrest Kid Curry's brother, Lonny, at his aunt's home. Lonny was killed in the shootout that followed, and his cousin Bob Lee was arrested for rustling and sent to prison in Wyoming. On March 28, Kid Curry and News Carver were pursued by a posse
