Dec. 7, 1982 — 21-year-old Debra "Debbie" Sue Carter drove home, where she lived alone, after working a late-night shift as a waitress at the Coachlight bar and restaurant in Ada. An unknown assailant knocked on her door and proceeded to force their way in, raping and strangling Carter with her own belt and the cord of an electrical blanket.
Dec. 8, 1982 — The following morning, Carter was found dead by her friend. No suspects were pursued for quite some time, but the lead detective on the case, Dennis Smith, insinuated that the police knew who did it, but they just didn't have evidence.
March 1983 — Ron Williamson, a man with multiple past arrests who happened to live nearby Carter's apartment, was interviewed by police investigators: Dennis Smith, Gary Rogers, Mike Baskin, and Chris Ross. According to an eyewitness named Glen Gore, Williamson was reportedly at the Coachlight the night of Carter's death and was seen harassing her before she left.
June 1983 — Dennis Fritz, Williamson's close friend, was interviewed by police in connection to the murder, but no arrests were made.
