Wonderland (Blu-ray)

On the afternoon of July 1, 1981, Los Angeles police responded to a distress call at 8763 Wonderland Avenue in Laurel Canyon and discovered a grisly quadruple homicide. Ron Launius, Billy Deverell, Barbara Richardson and Joy Miller were found brutally murdered, bludgeoned to death with a pipe, and Launius's wife, Susan, left in critical condition. The police investigation that followed led by detectives Sam Nico, Louis Cruz and Mike Peters would unearth a seedy world of drugs and violence, ultimately revealing a motley crew from L.A.'s underbelly including ex-con David Lind, nightclub impresario Eddie Nash, and porn legend John Holmes as well as Holmes' estranged wife Sharon and his teenage lover Dawn Schiller.
