Edmund Emil Kemper was born on December 18, 1948, in Burbank, California—a child who would become one of America's most infamous serial killers. But his descent into violence began not in adulthood, but at 15 years old.
On August 27, 1964, Kemper murdered his grandmother, Maude Matilda Kemper, shooting her once in the head and twice in the back before stabbing her repeatedly. He then killed his grandfather, Edmund Emil Kemper Sr., with a rifle in the driveway. After committing both murders, Kemper called police himself and reported what he had done.
What happened next would prove catastrophic for his future victims. Despite the brutality of his crimes, Kemper spent fewer than five years in confinement and treatment. His juvenile criminal record was expunged, and he received a diagnosis of schizophrenia—though he would later admit to fabricating the auditory hallucinations that supposedly justified the diagnosis. Released to his mother's care, Kemper was back in society with minimal accountability for double homicide.
For nearly a decade, he remained relatively quiet. Then, in May 1972, Kemper began a new killing spree that would last over a year.
Operating in Santa Cruz County, Kemper targeted hitchhikers—primarily college-aged women. Between May 1972 and April 1973, he murdered six female college students and one female high school student. His method was calculated and methodical: he would pick up the hitchhikers, then shoot, stab, smother, or strangle them. After transporting the bodies home, he would decapitate them, engage in necrophilia, and dismember the remains. The press dubbed him the "Co-ed Killer."
But Kemper's killing spree wasn't limited to strangers. On Good Friday in April 1973, he turned on his own mother. He struck her in the head with a hammer, cut her throat with a knife, and decapitated her. In an act of particular cruelty, he removed her hands and larynx, disposing of the larynx in the garbage disposal. Shortly after murdering his mother, Kemper also killed her friend by strangulation.
