Billy Wellman was 69 when he was last seen at a Crockett, Texas bus station on May 13, 1991, intending to travel to California for a visit. It is unknown whether he ever reached that destination, and he has not been seen or heard from since; his case is classified as an endangered missing person.

Wellman was born June 8, 1921, and is described as a white male, 5 feet 7 inches, about 185 pounds, with gray hair and blue eyes. Distinguishing features include a prominent scar on his forehead, a tattoo on his left shoulder of a fist with the middle finger raised, and dentures. Authorities have also classified him as disabled.

Few details are available about the circumstances of his disappearance and the case remains unsolved. Anyone with information about where Billy Wellman might have gone after May 13, 1991, is asked to come forward.
