During the 1970s and 1980s, Las Vegas was plagued by a series of unsolved murder cases that involved young girls who went missing under similar circumstances and were found dead with similar causes of death. The victims, who were often students, were usually strangled or suffocated, and their bodies were left in remote areas. Despite extensive investigations, the killer or killers responsible for these murders have never been identified, and the cases remain unsolved to this day.
