The Hillside Strangler: Story, Cast and Series Facts

Story and premise

The Hillside Strangler explores the infamous murders that gripped Los Angeles in the late 1970s and the exhaustive investigation that followed. 

In the late 1970s, Los Angeles was the serial murder capital of the world. The Freeway Killers. The Toolbox Killers. The Dating Game Killer. The Skid Row Slasher. But none terrorized this city of millions more than the Hillside Strangler, a phantom who struck without warning, abducting, raping, and murdering a dozen women and girls and leaving their bodies displayed on the hillsides like grim trophies. These crimes sparked the largest manhunt in LA's blood-soaked history, led by a relentless homicide detective named Frank Salerno. His dogged pursuit led to the strangler's capture and the revelation that these vicious acts were perpetrated by two men, Kenneth Bianchi and his cousin Angelo Buono.
