Notable American serial killers include David Berkowitz (“Son of Sam”), who killed 6 people in New York City in 1976–77; Ted Bundy, a killer and rapist who confessed to 28 murders but may have actually killed hundreds in the late 20th century; Jeffrey Dahmer, who murdered 17 people and engaged in cannibalism and necrophilia; John Wayne Gacy, whose killing of 33 men in the 1970s shocked his community, where he performed as a clown at charity events; and Ed Gein, who inspired the horror films Psycho (1960), Texas Chainsaw Massacre (1974), and The Silence of the Lambs (1991).
