In October 1877, U.S. Marshal Wiley Standifer, Yavapai County Sheriff Edward Franklin Bowers, Prescott Constable Frank Murray, Virgil Earp, and a man named McCall attempted to arrest John Tallos and an accused murderer named Wilson. While the others rode on horseback or carriages, Virgil ran on foot after the posse that pursued the two men to the edge of town, where a gun fight broke out. Virgil spotted one of the two men under a tree, reloading his pistol. Using a Henry rifle from a distance, Virgil shot him through the head, killing him.
