In 1906, Western Federation of Miners member Harry Orchard, who would later admit to working for the Pinkerton Detective Agency and spying for the Cripple Creek Mine Owners' Association, assassinated former Idaho Governor Frank Steunenberg. Pinkerton Agent James McParland coerced Orchard into implicating WFM Secretary-Treasurer Bill Haywood and other WFM officials. McParland then had the WFM leaders illegally arrested in Colorado and transported to Idaho by a secret train after using extradition papers which falsely claimed the three men had been present at Steunenberg's murder.
