Ed Kemper is a literal giant of true crime history. Standing 6 feet 9 inches and weighing 300 pounds, he wasn't just physically imposing; he was terrifyingly smart. Most people know him from the Netflix show Mindhunter as the articulate, soft-spoken killer who helped the FBI.
But honestly? The real story is way darker than the TV version.
Kemper, often called the Co-ed Killer, is one of the few serial murderers who actually stopped himself. He didn't get caught by a brilliant detective. He didn't slip up and leave a fingerprint at a crime scene. He finished his "work," went to a payphone in Colorado, and called the cops because he was bored of the killing.
The Making of a Monster in Santa Cruz
To understand why Ed Kemper did what he did, you've gotta look at his mother, Clarnell Strandberg. Their relationship was toxic. That’s putting it lightly. Clarnell was an abusive alcoholic who reportedly forced Ed to sleep in a dark basement because she was afraid he would "molest" his sisters.

She mocked his height. She belittled his intelligence. Basically, she spent years making him feel like a freak.
When Ed was 15, he shot both of his grandparents. He told the police he "just wanted to see what it felt like to kill Grandma." After a stint in Atascadero State Hospital, he managed to convince the doctors he was cured. He was so good at manipulating them that they even let him help administer psychiatric tests to other inmates.
Think about that. A budding serial killer was helping psychologists "fix" other people.
The Co-ed Killer Spree (1972–1973)
Once he was out, Kemper settled back into life in Santa Cruz. He was a regular at a local bar called the Jury Room, where he hung out with police officers. They liked him. He was "Big Ed," the friendly guy who wanted to be a cop but was too tall for the force.
While he was buying beers for detectives, he was hunting college students.
- Mary Ann Pesce and Anita Luchessa: His first victims after his release. He picked them up hitchhiking, murdered them, and took them back to his apartment.
- Aiko Koo: A 15-year-old dance student. This murder was particularly brutal because Kemper accidentally locked his keys in the car while she was still inside. She actually let him back in, not knowing what was about to happen.
- Cindy Schall: He buried her head in his mother’s garden, facing her bedroom window, just so his mother would "have someone to talk to."
The psychological warfare Kemper waged against his mother was the driving force behind everything. Every girl he killed was a "surrogate" for Clarnell. He was killing his mother over and over again until he finally worked up the nerve to kill the real thing.
Why Ed Kemper Actually Mattered to the FBI
The FBI’s Behavioral Science Unit, led by John Douglas and Robert Ressler, owed a lot of their early success to Kemper. Most killers they interviewed were impulsive or had low IQs. Kemper had an IQ of 136.
He was able to explain the "why" behind his actions with clinical precision. He described the "cooling-off period" and how the urge to kill would build up like a physical pressure. He told them about how he would practice picking up girls and letting them go, just to see if he could lure them into his car.
He basically gave the FBI the roadmap for modern criminal profiling.
The Final Act
In April 1973, Kemper finally did it. He killed his mother with a hammer while she slept. Then he killed her best friend, Sally Hallett, because he didn't want Sally to find the body and call the cops.
After that, the "need" to kill just evaporated. He drove across the country, realized no one was looking for him, and called the Santa Cruz police himself. They didn't even believe it was him at first. They thought "Big Ed" was playing a joke.
Where is Ed Kemper Now?
As of 2026, Ed Kemper is still alive. He’s 77 years old and resides at the California Medical Facility in Vacaville. He’s not the imposing giant he used to be. Recent reports from his 2024 parole hearing—which he didn't even attend—describe him as being in poor health, using a wheelchair, and generally being "done" with the outside world.
He has consistently waived his right to parole. He’s actually said on record that he knows he should never be released.
"I'm as happy going about my life in prison," he once told his lawyer.
Key Takeaways for True Crime Enthusiasts
If you're studying the Kemper case, keep these specific points in mind:
- Intelligence isn't a safeguard: High IQ doesn't prevent psychopathy; it just makes the killer better at hiding it.
- The "Mother" Archetype: Kemper is the textbook case for how extreme maternal abuse can manifest in violent misogyny.
- Self-Surrender: He is a rare example of a serial killer who chose to end his own spree because his "mission" (killing his mother) was complete.
To get a deeper look at the actual transcripts of his interviews, you can look for the book Whoever Fights Monsters by Robert Ressler. It provides the most accurate, non-dramatized account of what it was like to sit across the table from a man who knew exactly how broken he was.
Check out the California Department of Corrections (CDCR) public records if you want to track his current status or future parole eligibility dates, though he likely won't ever see the sun outside of Vacaville again.
