Disappearance of Kelly Disney

In 1984, a girl named Kelly Disney went missing after fighting with her boyfriend at a party. Two officers were among the last people to see her, and she told them she was walking to a friend's house. Her family searched for her, but the cops deemed her a runaway, so the case went cold. 10 years later, someone found a skull in a car at the reservoir where people went to party. It was confirmed to be Kelly Disney's skull, and there were signs of trauma, but there was no further progress. Some locals believe the killer was her boyfriend. Others think there may have been a serial killer in the area, as 4 more girls went missing after Kelly. All of them went missing while walking at night.
