1. Introduction
Serial killers often evoke fear and curiosity in equal measure. Among them, Ed Kemper stands out not just because of the nature of his crimes, but because of his unsettling intelligence and self-awareness. Known for murdering 10 people, including his own mother and grandparents, Kemper’s case is both a horrifying tale of violence and a window into criminal psychology.
2. Early Life and Background
Edmund Kemper was born on December 18, 1948, in Burbank, California. He was the middle child and only son of Clarnell Elizabeth and Edmund Kemper II. From an early age, his life was marked by dysfunction. His parents had a deeply troubled relationship, leading to divorce when Ed was just a child.
Kemper’s relationship with his mother was particularly toxic. She was reportedly emotionally abusive, calling him a “real weirdo” and locking him in the basement for fear he might harm his sisters. His father, a World War II veteran, was largely absent post-divorce.
3. Troubled Childhood and Early Signs
Many signs of Kemper’s future pathology emerged early:
- At age 10, he buried a cat alive.
- Later, he killed another cat and stored its parts in his closet.
- He engaged in “playing executioner” games.
- He showed fascination with firearms and fantasized about violence.
Despite these red flags, there was little intervention. By his teenage years, he was over 6’4″ tall, socially isolated, and emotionally volatile.
4. First Murders: The Grandparents
At age 15, Kemper committed his first murders. Sent to live with his paternal grandparents on a ranch in North Fork, California, he felt isolated and angry. On August 27, 1964, he shot his grandmother with a rifle after an argument, and then killed his grandfather when he returned home—reportedly so he wouldn’t have to see his wife dead.
Kemper later said he wanted to see what it felt like to kill someone. He then called his mother and turned himself in.
5. Time at Atascadero and Psychological Evaluation
Rather than being tried as an adult, Kemper was sent to Atascadero State Hospital, a maximum-security facility for mentally ill convicts. There, he underwent extensive psychological evaluation and was diagnosed with paranoid schizophrenia, though some later experts dispute this.
Ironically, his intelligence (later measured at an IQ of 145-160) led to privileges. He even assisted psychiatrists by administering tests to other inmates.
After less than six years, at age 21, Kemper was deemed rehabilitated and released in 1969 against medical advice.
6. The Co-Ed Killings Begin
Upon release, Kemper moved back in with his mother, who now worked at the University of California, Santa Cruz. He began killing again in 1972, targeting young female students.
His victims were often hitchhikers, whom he would pick up in his car, drive to isolated locations, and murder. His methods included:
- Strangulation
- Shooting
- Stabbing
He would often mutilate, decapitate, and engage in necrophilia with the corpses—acts that deeply shocked even experienced investigators.
7. Modus Operandi and Patterns
Kemper’s killings followed a gruesome pattern:
- Pick up young female hitchhikers.
- Drive them to a secluded area.
- Kill them via strangulation, stabbing, or gunfire.
- Engage in post-mortem acts, often at his home.
- Dismember the bodies and dispose of them in remote areas.
He was always calm, methodical, and chillingly rational. His crimes spanned 1972 to 1973.
8. Victim List and Timeline
Kemper murdered a total of 10 known victims, including:
- Maude Matilda Hughey Kemper – Grandmother
- Edmund Emil Kemper I – Grandfather
- Mary Ann Pesce – College student
- Anita Luchessa – College student
- Aiko Koo – 15-year-old dancer
- Cindy Schall – Student at Cabrillo College
- Rosalind Thorpe – UCSC student
- Alice Liu – UCSC student
- Clarnell Strandberg – His mother
- Sally Hallett – His mother’s friend
His final murders—his mother and her friend—were particularly brutal and signaled the end of his killing spree.
9. Psychological Profile of Kemper
Experts have extensively studied Kemper’s psyche. He exhibits traits consistent with:
- Narcissistic personality disorder
- Antisocial behavior
- Sexual sadism
- High intelligence
- Emotional detachment
He was aware of his own mental issues and often spoke articulately about his crimes in interviews, unsettlingly devoid of remorse.
10. Arrest and Confession
After killing his mother and her friend in April 1973, Kemper fled to Pueblo, Colorado. Strangely, he called the police from a phone booth and confessed. Initially, they didn’t believe him.
Eventually, he provided detailed accounts of his crimes and led authorities to buried body parts. His calm and complete confession stunned law enforcement.
11. Trial and Sentencing
Kemper was found legally sane and stood trial for eight counts of first-degree murder. In November 1973, he was convicted and sentenced to eight life terms, to be served concurrently.
He was imprisoned at California Medical Facility in Vacaville, where he remains to this day.
