Back in August 1977 the 24-year-old vanished without trace from his home near Swink, OK and cops, suspecting foul play, have followed up numerous leads. Each has been nothing more than a blind alley, and the handsome red headed youngster, who was approximately six-feet-two inches and 180lbs has never been seen again.
Davis was wearing blue denim jeans, a blue denim shirt and a gold watch at the time of his disappearance and investigators say Davis' truck, a white and blue 1975 Ford XLT three-quarter ton, is also missing.
The license tag number is 440-699.
Cops remain convinced the truck is the key to solving the case, as they believe it may well lead them to Davis' remains.
His family, who have set up this Facebook page in his memory are also hopeful that someone will come forward with information.
