Angelo Buono Jr., one half of the killing partnership known as the Hillside Stranglers, died of a heart attack at age 67 while serving a life sentence without parole at Calipatria State Prison in California. He had been convicted of nine murders committed with his cousin Kenneth Bianchi in Los Angeles between 1977 and 1978, victims who were kidnapped, tortured and strangled before their bodies were dumped on hillsides around the city.
Buono ran an upholstery shop that served as a base for the pair, luring young women into his van before the killings. Bianchi, who was arrested first in Washington State, struck a deal and testified against Buono in exchange for avoiding the death penalty, a betrayal that helped seal his cousin's conviction after one of the longest and most expensive criminal trials in California history.
Buono spent the rest of his life in prison showing no remorse for the killings, dying quietly behind bars rather than facing execution.
