This episode deals with the real life murder of Wild Bill Hickok by Jack McCall. McCall shot Hickok in the back of the head on August 2, 1876. Wild Bill was only 39 years old when he died. At the time of his death, Hickok was playing poker at the Nuttal and Mann's Saloon in Deadwood. McCall claimed that Hickok killed his brother in Abilene, Kansas. McCall was tried in Deadwood and found innocent. He moved on to the Wyoming territory and bragged about the killing, even going so far as to claim it was a fair fight. Wyoming authorities refused to recognize the innocent verdict claiming Deadwood was an illegal settlement. McCall was re-tried in Yankton, Dakota Territory and hanged on March 1, 1877 at the age of 24.
