Investigating History's Mysteries The assassination of Sheriff Pat Garrett, one of the most notorious lawmen of the American West, remained one of the most puzzling and perplexing unsolved mysteries for more than a century. As a result of sophisticated forensic analysis of the historical crime scene, as well as the discovery of new evidence, the mystery has been solved. Most know Pat Garrett as the self-proclaimed slayer of the outlaw, Billy the Kid, on the night of July 14, 1881, in Fort Sumner, New Mexico. The event propelled Garrett into regional and national headlines and generated a momentum that led the lawman to consider seeking higher political offices. Garrett's plans were thwarted by his self-destructiveness, however. In spite of his notoriety, he was a bumbling lawman, a debtor, an alcoholic, an adulterer, and addicted to gambling. After being removed from his position as sheriff, he retired to a ranch in Uvalde, Texas, only to be summoned back to New Mexico to investigate the disappearance of Colonel Albert Jennings Fountain. In this pursuit, he failed once again. Garrett's downward spiral created a sense of desperation in the lawman, and his continuing difficulties caused him to lose what few friends he had and generate numerous enemies. In time, his enemies had had enough of him and decided he had to go.
