In the late 1970s, Los Angeles was gripped by terror as young women began disappearing from the streets, only to be found brutally murdered in the hills above the city. Known as the Hillside Strangler, the killer, or killers, posed as police officers to lure victims before assaulting and strangling them. The case turned out to involve two men: Kenneth Bianchi and Angelo Buono, cousins whose partnership became one of the most infamous serial killer duos in American history. Their methods were calculated and horrifying: abducting women, assaulting them, and then dumping their bodies in public areas across Los Angeles.The investigation was long and complex, complicated further by Kenneth Bianchi’s multiple personality claims and deceptive testimony. Despite the challenges, justice was eventually served: Angelo Buono was convicted on nine counts of murder and died in prison, while Kenneth Bianchi remains incarcerated with multiple life sentences, though he retains the possibility of parole.
