Angelo Buono, Jr. (October 5, 1934 - September 21, 2002) was, along with cousin Kenneth Bianchi, one of the Hillside Stranglers. Born in Rochester, New York. Buono was found dead on September 21, 2002 at Calipatria State Prison while serving a life sentence. Buono, who was alone in his cell at the time of his death, died of a heart attack.

Ironically, his name literally means "good angle".
