The premise
A serial killer stalks Los Angeles in the 1970s, leaving bodies on display throughout the Hollywood Hillside. After a man named Kenneth Bianchi is arrested in 1979 on the suspicion of a double homicide in Bellingham, Washington, it doesn’t take long for Los Angeles investigators to connect the dots back to the serial killer they dubbed “The Hillside Strangler.” But there’s a catch — through a series of explosive recorded interviews with various psychologists and psychiatrists, Bianchi claims that the perpetrator is NOT him; it’s actually his multiple personality, ‘Steve‘ — and that’s not all he has to say on the matter.
Horror Vault's take
In 1970s Los Angeles, a predator terrorizes the city by leaving victims prominently displayed across the Hollywood Hills — a case that would eventually grip the entire nation. This documentary series revisits the hunt for the killer known as the Hillside Strangler, culminating in an arrest that raises more questions than it answers. At the center of it all is a courtroom-ready psychological puzzle: can a man truly be innocent of crimes committed by another personality living inside him? Interviews, investigators, and insiders piece together one of true crime's most psychologically tangled cases.
