Patrick Floyd Jarvis "Pat" Garrett (June 5, 1850 – February 29, 1908) was an American Old West lawman, bartender and customs agent who became renowned for killing Billy the Kid. He was the sheriff of Lincoln County, New Mexico as well as Doña Ana County, New Mexico. He co-authored a book about Billy the Kid which, for a generation after the Kid's death, was deemed authoritative; however, historians have since found many embellishments and inconsistencies with other accounts of the outlaw's life. Garrett was murdered under unclear circumstances.
