At Beaver Utah on April 13 1866 Roy, as he was called but his friends and family was born the oldest of thirteen children. The Parker family moved to Circle Valley in 1879 an area known for lawlessness, there met Mike Cassidy and began riding with his gang at the age of sixteen. Mike Cassidy killed a rancher in Wyoming and had to flee justice, leaving young Roy in charge of the gang and as a token to mike Roy took the last name Cassidy.

Roy Cassidy branched out into robbing trains and then a two year stretch of robbing banks in Denver and Telluride Colorado. Just after that Roy assumed the name George Cassidy and took a break from the outlaw life.

George Cassidy worked as a butcher in Rock Springs, Wyoming getting the nickname “Butch”.  Butch tried to walk the path of the law abiding citizen, but failed in 1893 when he was arrested for stealing a horse. He was sentenced to the Wyoming State Prison and served eighteen months, when he got a full pardon, if he agreed to not practice his line of work in The Wyoming Territory.

Butch formed a gang know as the “Wild Bunch” in 1896.  The Wild Bunch was known for their flair during a robbery. One such case is on June 2, 1899 they used a warning lamp to stop the Union Pacific’s Overland Limited and uncoupled the express car. The guard inside refused to open the door so in an effort not to harm the guard, Butch avoided harming people wherever possible, only one stick of dynamite was used to open the door. However several sticks were strapped to the safe inside the rail car and it was blown to bits sending money into the air to float like confetti. The gang rode away with around $30,000.

Butch’s gang was made up of cold blooded , ruthless men he himself avoid unnecessary violence, a fact proven by an time when chased by a posse he never shot at one of the riders only fired at their horses. Later in his life he would claim to have never killed a man.

Staying one step in front of the law was becoming increasingly harder to do with the Pinkerton detectives dogging their trail constantly, they were wanted in five states, Cassidy decided to disband the Wild Bunch. After a short trip to New York, Butch and another member the Wild Bunch Harry “Sundance Kid” Longabaugh along with his mistress Etta Place went to South America to try their hand at ranching there. The trio took different route and joined up in Montevideo Uruguay.  They went to Argentina and started a lucrative sheep and cattle ranch.

Even though the outlaws were thousands of miles from the states where there was a price on their heads the Pinkertons Agent still track their movements. Butch sensed danger and left Argentina, with Sundance and Etta. However as they left they robbed three Argentina banks and a Bolivian train. Etta contracted appendicitis temporarily putting the crime spree on hold.

Etta received treatment in Denver, and after a drinking binge Butch shot up his hotel room. To avoid being jailed he and Sundance left Etta behind and went back to South America. The duo worked at a Peruvian gold mine and occasionally took a trip into Bolivia to rob a bank or a train or maybe a local store. This ended when the Bolivian police caught up to them in 1908.

Some stories say that Butch and Sundance died in a gunfight in a Bolivian border village. However other stories relate that Butch escaped Bolivia and returned to the U.S.A., and took the name William Thadeus Phillips from Des Moines, Iowa and worked as a mechanical engineer. The next spring he married Gertrude Livesay and moved to Globe Arizona, where William was a mercenary for the Mexican Revolution. From there they moved to Spokane, Washington where he opened a office equipment business and as a result of the Great Depression  was forced to sell in the early 1930’s William Thadeus Phillips died of cancer not a bullet in Bolivia.
