Pat Garrett —
Patrick Floyd Jarvis "Pat" Garrett was an American Old West lawman, bartender and customs agent who became renowned for killing Billy the Kid. He was also the sheriff of Lincoln County, New Mexico as well as Doña Ana County, New Mexico. He coauthored a book about Billy the Kid which, for a generation after the Kid's death, was used by historians as a factual account of his life; however, historians have since found in his book many embellishments and inconsistencies with other accounts of the outlaw's life. Pat Garrett also became one of President Theodore Roosevelt's three "White House Gunfighters" when Roosevelt appointed him Collector of Customs in El Paso. Garrett was murdered under unclear circumstances... (wikipedia)
