Theodore Robert "Ted" Bundy (born Theodore Robert Cowell; November 24, 1946 – January 24, 1989) was an American serial killer, rapist, kidnapper, and necrophile who assaulted and murdered many young women between 1974 and 1978. After more than a decade of denials he confessed to 30 homicides shortly before his execution; the true total remains unknown, and could be much higher.

Richard Trenton Chase (May 23, 1950 – December 26, 1980) was a United States serial killer who killed six people in the span of a month in Sacramento, California. He was nicknamed "The Vampire of Sacramento" because he drank his victims' blood and cannibalized their remains.

Albert Henry DeSalvo (September 3, 1931 – November 25, 1973) was a criminal in Boston, Massachusetts who confessed to being the "Boston Strangler", the murderer of 13 women in the Boston area.

Gacy buried 26 of his victims in the crawlspace of his home and three others elsewhere on his property, discarding the remaining four victims in a nearby river. Gacy became known as the "Killer Clown" due to his charitable services at fundraising events, parades and children's parties where he would dress as "Pogo the Clown," a character he devised himself.
