Was the legendary outlaw Butch Cassidy killed in Bolivia or did he die in obscurity?

History · Published 3 October 2026 Swipe more like this →

In short: Robert Parker, better known as Butch Cassidy, was the notorious leader of the Wild Bunch. While history books often place his final moments in a 1909 shootout in Bolivia, persistent rumors suggest he may have escaped, lived on for decades, and eventually died in the American West in 1937.

Born Robert Parker in 1866, the future outlaw adopted his famous alias from a mentor named Mike Cassidy. His criminal career began in earnest during the 1880s and 1890s, characterized by a series of bank and train robberies across the American West. After serving time in the Wyoming State Prison between 1894 and 1896, he formed the Wild Bunch, a shifting collective of criminals that included his closest associate, Elzy Lay, and eventually Harry Longabaugh, the Sundance Kid.

As law enforcement, including Pinkerton detectives, tightened their grip on the gang, Cassidy and the Sundance Kid fled to South America in 1901, accompanied for a time by Etta Place. They attempted a legitimate life as ranchers in Argentina’s Chubut province from 1902 to 1906, but the pull of their former life proved too strong. They returned to a cycle of drifting and robbery, targeting banks and mine stations across the continent.

The mystery surrounding Cassidy’s death remains one of the most enduring debates in Western history. The official account, supported by Pinkerton agents, claims he and Sundance were trapped by soldiers near San Vicente, Bolivia, in 1909, where Sundance was killed and Cassidy took his own life. However, conflicting narratives persist. Some accounts suggest they died in a 1911 robbery in Uruguay, while others claim Cassidy survived to live a quiet life, potentially dying in obscurity in the United States as late as 1937. These competing versions ensure that the man behind the myth remains as elusive in death as he was in life.
