Gena Lee Turner, 20, was murdered on May 4, 1986, during a trip to Lake Hawkins, about 100 miles east of Dallas. She was with 19-year-old Bryan Boone and 18-year-old Suzanne Harrison when they encountered Jerry Walter McFadden, a convicted rapist and murderer. Turner and Boone were shot with a .38-caliber pistol; Harrison was sexually assaulted and then strangled with her own underwear.

McFadden, known as The Animal, had prior convictions for multiple rapes and had been paroled in 1985. Witnesses placed him near the scene and investigators said ammunition found in his possession matched the bullets used in the killings. He was arrested on May 6, 1986, escaped from jail briefly while taking a female prison officer hostage, and was recaptured following a massive manhunt. Forensic work years later linked him by DNA to an unsolved 1979 murder in Oregon.

Anyone who knew Gena, Bryan, or Suzanne, or who has information about that day at Lake Hawkins, is asked to come forward.
