David Allen Dunaway, 29, was last seen on May 10, 1981, in Houston, Texas. At the time he worked as a drywall contractor and was described as paranoid and carrying a sawed-off shotgun wrapped in a paper bag. He had a history of drug use, a metal plate in his jaw, and wore prescription eyeglasses.

Family members said it was highly uncharacteristic for him to disappear without notifying them, since he had a wife and two young sons. The case is listed as endangered and remains unsolved despite extensive investigations; the Houston Police Department is handling the matter.

If anyone knew David, saw him around May 10, 1981, or has information about his whereabouts, please come forward.
