How Many People Did Ed Kemper Kill? A Complete Victim List
Kemper’s victim count is reported slightly differently depending on the source. Wikipedia lists 8 people for the 1972‑1973 spree (7 women and 1 girl), while other sources include his grandparents to reach a total of 10. The following breakdown covers all confirmed deaths.
Grandparents (1964)
In August 1964, after an argument with his grandmother, a 15‑year‑old Kemper shot and killed both his paternal grandparents using his grandfather’s rifle. He was later diagnosed with paranoid schizophrenia and sent to Atascadero State Hospital.
Santa Cruz Coed Murders (1972‑1973)
After his release in 1969, Kemper began targeting young female hitchhikers in Santa Cruz County, California. He would lure them into his vehicle, drive to a secluded area, and murder them. He then brought the bodies home for acts of necrophilia, decapitation, and dismemberment. The six known victims were all college students.
Murder of His Mother and Her Friend (1973)
On April 20, 1973, Kemper beat and stabbed his mother, Clara Kemper, to death in her home. He also killed her friend Sally Helten, who had arrived shortly afterward. He placed his mother’s vocal cords in the garbage disposal, an act that authorities later interpret as symbolic rage.
Kemper has made conflicting statements about whether he consumed parts of his victims’ bodies. Most reliable sources confirm necrophilia but treat cannibalism as an unverified claim. Official records do not universally support this rumor.
Where Is Ed Kemper Now? Prison, Parole, and Current Status
Sentence and Incarceration
After turning himself in to police in Pueblo, Colorado, in April 1973, Kemper was found sane and guilty. He requested the death penalty, but because capital punishment was temporarily suspended in California, he received eight concurrent life sentences. He is held at the California Medical Facility in Vacaville.
Parole Status
Kemper has repeatedly waived his parole hearings, stating he is “happy in prison.” As of 2025, he remains incarcerated with no scheduled future hearings. Given his age (77) and the severity of his crimes, release is considered extremely unlikely.
At the time of Kemper’s sentencing, California had no active death penalty due to court rulings. This legal circumstance is why he received life terms instead of execution.
Ed Kemper in Media: Documentaries, Mindhunter, and Interviews
Portrayal in Mindhunter
The Netflix series Mindhunter, based on John Douglas’s book, premiered in 2017. Actor Cameron Monaghan portrayed Kemper in Season 1, Episode 5 (“The Co‑ed Killer”). There is no “Mindhunter 2025” series; the show has not been renewed.
Interviews with FBI Profilers
Kemper granted extensive interviews to FBI Special Agents John E. Douglas and Robert Ressler of the Behavioral Science Unit. His calm, articulate, and emotionally detached manner helped shape modern criminal profiling. French writer Stéphane Bourgoin also interviewed him in 1991.
Documentary Appearances
Several documentaries cover his life and crimes, including The Killing of America and an Apple TV+ film. His case continues to be examined in true‑crime media.
Despite occasional speculation, no new season or edition of Mindhunter has been announced. All appearances of Kemper on screen remain limited to the 2017 series and earlier documentaries.

IQ Scores
Initial testing at Atascadero State Hospital measured his IQ at 136. A later test produced a score of 145, placing him in the genius range. He used his intelligence to manipulate evaluators and later to provide detailed self‑analysis during interviews.

His physical size (6 ft 9 in) and intellect (IQ 145) created a commanding presence he used to gain trust before killing.
