Jeff Mynatt spent much of his adult life in law enforcement. He was a deputy U.S. marshal in Indian Territory, a lawman in various Texas locales, and a Texas Ranger for several years. He was also a member of the Wyoming Invaders who hunted for rustlers in 1892 (Mynatt is seated second from left, with newspaper).
He was a rough character. One time, Mynatt believed a newspaper editor in Gainesville, Texas had slandered him. He broke the man’s jaw and knocked out several teeth. Mynatt was convicted of assault and paid $500—but kept his job.
