Or... if there is an oblique connection to the Wonderland murders? (Unsolved)
From Wiki...
The Wonderland murders, also known as the Four on the Floor Murders or the Laurel Canyon Murders, are four unsolved murders that occurred in Los Angeles on July 1, 1981. It is assumed that five people were targeted to be killed in the known drug house of the Wonderland Gang, three of whom were present. All three of them, Ron Launius, Billy DeVerell, and Joy Miller, along with accomplice Barbara Richardson, died from extensive blunt-force trauma injuries. Only Ron Launius’ wife, Susan Launius, survived the attack, allegedly masterminded by organized crime figure and nightclub owner Eddie Nash. He, his henchman Gregory Diles, and porn star John Holmes were at various times arrested, tried, and acquitted for their involvement in the murders. LAPD detectives were on record saying the crime scene was bloodier and more gruesome than that of the Tate-LaBianca murders.
Lots of weird stuff - Laurel Canyon - Not many of those people left alive are they? There was a book written about Laurel Canyon - not just the wonderland murders.
Anybody ever read it? Hoping for a cliff notes version.
