Gregory Keith Mann Jr., 20, disappeared from Wichita Falls, Texas, after being dropped off near his apartment at Fountaingate Apartments about 11:45 p.m. on the night of May 10, 1997. Friends watched him walk toward the building but there is no evidence he ever entered; he was never seen or heard from again.

That day he had borrowed a red 1996 Ford Mustang from the Ford dealership where he worked. The car was found the next morning in a church parking lot not far from his parents’ home. Investigators reported the vehicle had been cleaned, the trunk partially open and a panel inside dislodged, but no significant clues were recovered. Gregory’s apartment still contained his belongings, and there was no unusual activity on his bank or credit cards. He had been planning to move in with his fiancée.

The circumstances and the condition of the car prompted investigators to suspect foul play. The FBI took part in the investigation, but the case remains unsolved. If anyone knew Gregory, his movements that night, or saw the red 1996 Mustang around May 10–11, 1997, please come forward with information.
