The Wonderland murders, also known as the Four on the Floor Murders[1] or the Laurel Canyon Murders, are four unsolved murders that occurred in Los Angeles on July 1, 1981.[2] It is assumed that five people were targeted to be killed in the known drug house of the Wonderland Gang, three of whom—Ron Launius, William "Billy" Deverell, and Joy Miller—were present. Launius, Deverell, and Miller, along with the girlfriend of an accomplice, Barbara Richardson, died from extensive blunt-force trauma injuries. Only Launius' wife Susan survived the attack, allegedly masterminded by organized crime figure and nightclub owner Eddie Nash. Nash, his henchman Gregory Diles,[3][4] and porn actor John Holmes were at various times arrested, tried, and acquitted for their involvement in the murders.
