Here’s a synopsis: “The Hillside Strangler’s murders in the 1970s sparked the largest manhunt in L.A.’s history, led by relentless homicide detective Frank Salerno. His dogged pursuit led to the strangler’s capture and the shocking revelation that these vicious acts were perpetrated by two men: Kenneth Bianchi and his cousin Angelo Buono.”

“After the longest criminal trial in U.S. history, both were sentenced to life in prison. The case defined Salerno’s career and set him on the path to later bring down the Night Stalker. Now, for the first time in over 40 years, Salerno tells his story, revisiting the case that changed him forever. The docuseries also features unprecedented access to Kenneth Bianchi himself, who has never before been willing to share his story on camera. Angelo Buono died behind bars in 2002, but Bianchi remains in prison and speaks for the first time about the murders that shocked Los Angeles.”

Kenneth is currently serving a sentence of life in prison in Washington State Penitentiary, and was most recently denied parole in 2025.
