Edmund Emil Kemper III, commonly referred to as Ed Kemper, is a convicted American serial killer and necrophile whose crimes in the early 1970s shocked the nation and left an indelible mark on the study of criminal psychology. Known as the “Co-Ed Killer,” Kemper’s actions and confessions provided key insights into the mind of a highly intelligent, articulate, and methodically violent individual.
His case is often cited in academic and forensic circles for its complex psychological themes, early signs of pathology, and cooperation with law enforcement after his arrest. This article explores Kemper’s background, criminal activities, psychological profile, and legacy in criminal justice studies.
Ed Kemper was born on December 18, 1948, in Burbank, California. He grew up in a tumultuous household marked by emotional abuse and instability. His relationship with his mother, Clarnell Strandberg, was especially strained and would become central to his later behavior.
Kemper exhibited troubling behavior from a young age, including cruelty to animals and signs of emotional detachment. He was known to be extremely intelligent, but socially awkward and often isolated from peers.
Kemper’s parents divorced during his early adolescence. He lived with his mother in Montana, where their toxic relationship intensified. He was eventually sent to live with his grandparents in rural California, a decision that led to his first violent act.
At the age of 15, Kemper committed his first murders by shooting his grandmother during an argument, then his grandfather as he returned home. Kemper later stated that he “just wanted to see what it felt like to kill Grandma.”
This shocking double homicide led to his institutionalization rather than traditional incarceration, based on psychological evaluations.
Kemper was diagnosed with paranoid schizophrenia, though this diagnosis would be debated later. He was sent to Atascadero State Hospital, a secure facility for criminally insane youth. During his time there, he demonstrated high intelligence and a capacity for manipulation, even gaining access to detailed psychological assessments of other inmates.
He was released at age 21, deemed rehabilitated by psychiatric staff despite objections from some officials.
After release, Kemper moved in with his mother, now living in Santa Cruz, California. Despite being on parole, he was able to secure employment and was not closely monitored. Over time, his urges escalated.
Between 1972 and 1973, Kemper murdered six young women, most of whom were college students hitchhiking in the Santa Cruz area. He would pick them up, gain their trust, and later murder them by strangulation, shooting, or bludgeoning.
After the murders, he often engaged in necrophilia, dismemberment, and kept trophies such as body parts. He disposed of the remains in remote locations.
Kemper’s killings followed patterns:
His lack of remorse and detailed recollection of each act provided a wealth of psychological data.
In April 1973, Kemper murdered his mother, bludgeoning her with a hammer and subsequently decapitating her. He also committed post-mortem acts on her body and placed her severed head on a shelf.
He later killed her best friend, whom he lured to the house under false pretenses, then fled the state.
Kemper eventually called the police from a phone booth in Colorado, confessing to his crimes. Initially met with disbelief, he persisted and provided detailed accounts of all his murders.
Upon his return to California, Kemper fully cooperated with authorities, leading them to evidence and locations of the bodies.
Kemper’s IQ was measured above 140, placing him in the genius category. He was articulate, thoughtful, and capable of discussing complex psychological and emotional themes.
Despite his violent acts, he came across as calm and rational, which fascinated and disturbed psychologists.
Kemper has been associated with traits of:
However, his willingness to reflect on his actions and engage in deep introspection made him unique among serial offenders.
Kemper frequently spoke about his hatred toward his mother and how it manifested in his choice of victims. His crimes were, in his own words, symbolic “rehearsals” for the final act of killing her.
He described feeling like two people—one calm and one enraged—a duality often observed in other violent offenders.
Kemper was charged with eight counts of first-degree murder. He pled not guilty by reason of insanity, but the court found him legally sane at the time of the murders based on testimony and psychiatric review.
In 1973, Kemper was sentenced to multiple life sentences and imprisoned at California Medical Facility in Vacaville. He has been denied parole several times and has waived others, indicating no desire for release.
In prison, Kemper has been described as cooperative, intelligent, and helpful. He has held various duties, including narrating audiobooks for the blind, for which he received informal praise.
He has also participated in psychological studies, including interviews for the FBI’s Behavioral Science Unit, contributing to early criminal profiling techniques.
Kemper has periodically appeared before parole boards but has expressed that he is not fit for release. His introspective statements are often chilling, as he acknowledges the danger he poses to society.
Kemper’s interviews became foundational for FBI agents like John Douglas and Robert Ressler, who used his insights to develop offender profiling strategies.
His ability to articulate motive, method, and emotional reasoning allowed law enforcement to build psychological profiles used to track and understand other serial killers.
Today, Kemper’s case is used in:
His case exemplifies the intersection of intelligence, trauma, mental illness, and unchecked violence.
Kemper has been featured in:
His candidness and articulate demeanor create a chilling juxtaposition to his crimes.
Kemper has inspired or appeared as a character in:
These portrayals often emphasize his dual nature—intellectual and monstrous.
Some argue that the fascination with Kemper borders on glorification, raising concerns about media ethics. Others view his case as an essential educational resource.
Critics urge greater focus on the victims rather than the perpetrator. The women Kemper murdered are often overshadowed by his intellect and cooperation with authorities.
Many professionals agree that studying Kemper’s case offers valuable lessons about warning signs, system failures, and human behavior. However, context and sensitivity are crucial.
Ed Kemper remains one of the most studied and debated figures in American criminal history. His life reflects a confluence of childhood trauma, extreme intelligence, untreated pathology, and unchecked escalation toward unimaginable violence. More than a killer, he has become a case study in how psychological complexity intersects with criminal behavior.
His cooperation with authorities has contributed significantly to forensic science and profiling, yet his horrific actions serve as a grim reminder of what can happen when systemic oversight fails.
As researchers, law enforcement, and educators continue to learn from Kemper’s story, the emphasis must remain on prevention, ethical discussion, and remembrance of the victims whose lives were tragically lost.
Ed Kemper was convicted of eight murders, including his mother and her friend, although he confessed to several more, including his grandparents.
He was given the nickname because many of his victims were female college students whom he picked up while they were hitchhiking in the early 1970s.
He was diagnosed with various mental disorders but was found legally sane during his trial, meaning he was responsible for his actions under the law.
Yes, as of the latest records, Ed Kemper is alive and serving multiple life sentences at a prison in California.
Yes, he was instrumental in the development of criminal profiling, particularly with the FBI’s Behavioral Science Unit in the late 1970s.
His intellect, introspection, and cooperation with authorities distinguish him from many others. His articulate explanations provide unique insight into criminal psychology.
