Background
Kenneth Alessio Bianchi, born on May 22, 1951, in Rochester, New York, is an American serial killer known for the infamous "Hillside Strangler" murders. Alongside his cousin, Angelo Buono Jr., Bianchi terrorized Los Angeles between October 1977 and February 1978, targeting young women and girls. The duo's heinous crimes involved kidnapping, sexual assault, torture, and murder, with victims ranging in age from 12 to 28 years old.Modus Operandi
Bianchi and Buono employed a cunning method to ensnare their victims. Posing as undercover police officers, they used fake badges to lure unsuspecting women into their vehicle, a car they claimed was an unmarked police car. Once the victims were in their control, they were taken to Buono's residence, where they endured horrific acts of torture and sexual assault before being strangled to death. The bodies were then discarded on hillsides in the Los Angeles area, leading to the media dubbing them the "Hillside Stranglers."Victims
