Shortly before midnight on Friday, May 9, 1980, neighbors on Cherry Ridge reported hearing gunshots and saw a 1973 tan/gold Mercury Montego driving away at high speed. The car belonged to Margaret and Keith Conable, who lived at 458 Cherry Ridge. The next morning a neighbor found the couple’s house open and discovered both Margaret, 50, and Keith, 53, bound and badly beaten to death. The vehicle was missing and several CB-style radios taken from the home. The couple’s Mercury bore Texas plate ECF275.

Investigators have pursued several leads over the years but the case remains unsolved and no clear motive has been established for the attack. The radios and the Mercury Montego have not been recovered. Anyone with information about the car, the radios, or the events of that night is asked to come forward.
