In 1874, he, along with his brother, became a cattle driver in Atascosa County, south of San Antonio. The two formed a cattle-transporting company, the San Antonio Ranch Company, which drove cattle to Kansas via the Chisholm Trail. One of his cattle drive bosses was his first cousin Lewis Warren Neatherlin. Neatherlin's brother, James Franklin Neatherlin, also the Slaughter brothers' first cousin, assisted on the drive. In the late 1870s, Slaughter left Texas for New Mexico, where he traded cattle and planned to start a ranch. However, he eventually decided to establish the ranch in the Arizona Territory. Initially settling in Charleston, Arizona, he later purchased the San Bernardino Ranch, on the U.S.–Mexico border near Douglas, in 1884. In 1886, Slaughter was elected sheriff of Cochise County, Arizona, five years after the infamous Gunfight at the O.K. Corral. He was later re-elected to a second term. As sheriff, he helped track Geronimo, the Apache chief who was caught on the San Bernardino Ranch. Slaughter fought for law and order with his six-shooter, a repeating shotgun, and a Henry rifle. He arrested desperados like the Jack Taylor Gang and brought them to justice. He also became a prominent poker player, often playing all night long. He was reportedly good at bluffing. He often played with the cattle baronJohn Chisum. Once, in San Antonio, Texas, he was cheated by cattle rustlerBryan Gallagher. Slaughter claimed the pot but Bryan fled. Slaughter tracked down Gallagher all the way to New Mexico at Chisum’s ranch and shot him down.
Personal life
Slaughter married Eliza Adeline Harris on August 4, 1871. Of their four children, only two, Addie and Willie, survived until adulthood. Eliza died in 1877 of smallpox in Tucson. On April 16, 1879, Slaughter, at the age of thirty-seven, married eighteen-year-old Cora Viola Howell at Tularosa, New Mexico Territory. The Slaughters had no children of their own, but they adopted several children, including Apache May, whom Slaughter encountered in 1896 while chasing the Apache Kid in Mexico. Years later, when he became ill, the Slaughters moved to an apartment on Twelfth Street in Douglas, Arizona.
Death
Slaughter was found on the morning of February 16, 1922, in his Douglas apartment, having died sometime during the previous night.
The ABC television miniseriesTexas John Slaughter, with Tom Tryon in the title role, was inspired by Slaughter's life story. The series began as a Wonderful World of Disney series in 1958. William W. Johnstone's Texas John Slaughter series features Slaughter as a main character. John Slaughter is also written about as the main character in the book Gun Justice: The unforgettable story of Texas John Slaughter, one of the greatest gunfighters of the old west by Jason Manning. Published in 1999, it chronicles his life from a ranch hand in Texas to the Arizona frontier. His life is told by himself, often when explaining his life to friends. Robert Taylor hosted and played John Slaughter in the 1968 episode, "A Short Cut through Tombstone", on the syndicated television anthology series, Death Valley Days. Buck Taylor played his deputy, Billy Stiles. Ned Romero was cast as the Geronimo Kid.
