David Williams was last seen on November 11, 1980 at the old service station/bar in Creston Junction at approximately 17:30 hours. He placed a phone call while at the service station before leaving as the passenger in a brown or tan Chevrolet Blazer with an unidentified white male subject, headed south on Hwy. 789. The Chevrolet Blazer was believed to belong to David Barker Jr. of Upton, WY, who is also a suspect in this investigation. David called his wife during the evening, saying he was driving south to check an oil rig and would be home late. He was not seen or heard from again. His body has never been located.
