Deputy U.S. Marshal Wyatt Earp led a federal posse that escorted Virgil Earp to the railroad, bound for his parents’ home in Colton, California. Wyatt shot and killed Frank Stilwell, who was lying in wait at the Tucson, Arizona rail yard. A few days later Wyatt gathered a larger posse and set out on a vendetta, determined to mete out justice that had evaded him. Wyatt never located Clanton, although they killed three other outlaw Cowboys, and the Earps and Holliday left the Arizona Territory in late April, 1882.
