After a man named Kenneth Bianchi is arrested in 1979 on the suspicion of a double homicide in Bellingham, Washington, it doesnāt take long for Los Angeles investigators to connect the dots back to the serial killer they dubbed āThe Hillside Strangler.ā But thereās a catch ā through a series of explosive recorded interviews with various psychologists and psychiatrists, Bianchi claims that the perpetrator is NOT him; itās actually his multiple personality, āSteveā ā and thatās not all he has to say on the matter.
