Clarnell Stage mentally abused Kemper and seemed to relish mortifying him, as a matter of fact. She travestied him, constantly calling him a “weirdo” and telling him that no woman would ever go out with him. Clarnell coerced Kemper, who was 10 years old at the time, to sleep in a locked basement because she was convinced Edmund would harm his own sisters. Reasonably enough, Kemper execrated his mother with a zealousness. Kemper commenced acting peculiarly, torturing and killing felines and other neighborhood animals amongst other acts.
As he got older, Kemper fought perpetually with his mother. He moved in with a friend as soon as he preserved enough money because of the constant fighting with Clarnell. In his mind, Kemper knew that he could avoid his mother, but he could never avoid the murderous rage that was waiting to manifest itself.
Kemper’s homicidal rampage was spread out over a year. He snatched the lives of 6 young female hitchhikers. Kemper would pick up the unwary girls, take them to sequestered areas, and shoot, stab, and strangle them. The gruesome acts of violence included dismemberment and even necrophilia. Kemper moved back in with his mother during the killings, bringing some of the corpses of his victims back to her house for his own sexual gratification, and even burying one of his victims in his mother’s garden.
April 21, 1973: While Clarnell was sleeping placidly, Kemper silently snuck into her room, caved in her head with a claw hammer, and slashed her throat open. Kemper also decapitated her and used her head as a dart board. He also ended up murdering his mother’s best friend, Sally Hallett, later on during that day. Kemper invited Hallett over for dinner and a movie. After showing up, she was strangled as well as decapitated. Kemper stole her vehicle and fled California, driving until he reached Pueblo, Colorado, where he phoned the police and confessed to murdering his mother and Hallett.
