Two other accomplices were uncovered by the investigation: Glenda Jean "Jesse" Ray (Ray's daughter) and Dennis Yancy. Yancy admitted to strangling his former girlfriend, Marie Parker, after Ray had kidnapped and tortured her. Yancy was convicted of second-degree murder and of conspiracy to commit first-degree murder, and was sentenced to two 15-year prison terms. After that murder, Ray allegedly admitted to having had an accomplice named Billy Bowers, a previous business partner, whom Ray also murdered. The Federal Bureau of Investigation sent 100 agents to examine Ray's property and surroundings, but no identifiable human remains were found.
