Ed Kemper: The Co-ed Killer’s Crimes and FBI Legacy

Few figures in American crime history pull people in quite like Edmund Kemper — a 6-foot-9 man who helped the FBI understand serial killers from the inside after killing 10 people in California between 1964 and 1973, including his grandparents, his mother, and six young women, before turning himself in (Britannica (encyclopedia entry)). What follows separates the documented record from the speculation, with the sources attached.

Full name: Edmund Emil Kemper III ·
Born: December 18, 1948 ·
Confirmed victims: 10 (1964–1973); 8 convictions ·
Status: Life imprisonment at California State Prison, Corcoran ·
Also known as: The Co-ed Killer ·
Height: 6 ft 9 in (2.06 m)

Nine data points, one pattern: Kemper’s case is documented in unusual depth for a 1970s serial murder investigation — yet a couple of headline numbers still depend on which source you read.

What is the latest verified information about Ed Kemper?

Current incarceration status

Institution: California State Prison, Corcoran · Sentence: Life imprisonment · Parole: Denied, most recently in 2024

Kemper remains in the custody of the California Department of Corrections and Rehabilitation. The official inmate lookup lists him at California State Prison, Corcoran, and parole has been denied repeatedly — most recently in 2024 (CDCR). A&E’s long-running true-crime coverage notes that he was held at the California Medical Facility during his incarceration (A&E).

Recent health and legal developments

• The most recent documented legal event is the 2024 parole denial; CDCR records show no change in his custody status.
• Kemper has not given recent public interviews; his recorded conversations with journalists, psychiatrists, and law enforcement date back to his decades in prison.
• The New York Times maintains a topic archive of Kemper coverage, a practical reference for tracking any new legal or institutional development (The New York Times).

The implication: the latest verified information about Kemper is mostly procedural — a denial, a custody listing, an archive update. The research chapter of his life closed decades ago; the institutional chapter is still writing itself.

What should readers know first about Ed Kemper?

Biographical summary

• Born: Edmund Emil Kemper III, December 18, 1948, Burbank, California.
• Height: 6 ft 9 in (2.06 m).
• Youth: Killed his grandparents at 15, spent years in state hospital care, and was released under supervision in the late 1960s.

Britannica’s biography places him among the most notorious serial killers in the United States, born in Burbank and standing 6 ft 9 in (Britannica). After killing his grandparents in 1964, he was committed to Atascadero State Hospital and later released under supervision; the killings resumed in the early 1970s.

Notable crimes and victims

• May 1972: Mary Ann Pesce and Anita Luchessa were murdered.
• September 14, 1972: Aiko Koo was murdered.
• January 7, 1973: Cindy Schall was murdered.
• February 5, 1973: Rosalind Thorpe and Allison Liu were murdered.
• April 1973: His mother and a family friend were murdered.

Those six young women, plus his mother and a family friend, make up the eight killings for which Kemper was tried; the case timeline compiled by Crime+Investigation UK documents each victim and date (Crime+Investigation UK). Add the grandparents killed in 1964, and the total rises to ten confirmed deaths.

The ‘Co-ed Killer’ label stuck because so many of the victims were college-age women, several of them hitchhikers — a description The New York Times’s archive has used for decades (The New York Times).

A timeline of the Kemper case

• December 18, 1948: Born in Burbank, California.
• August 27, 1964: Killed his grandparents at age 15.
• 1965–1969: Held at Atascadero State Hospital; later released under supervision.
• May 1972 – February 1973: Killed six young women in the Santa Cruz area.
• April 1973: Killed his mother and a family friend, then surrendered in Pueblo, Colorado.
• November 8, 1973: Convicted on eight counts of first-degree murder.
• 1980s–1990s: Gave extensive interviews to FBI Behavioral Science Unit agents.
• 2024: Parole denied; remains incarcerated.

The pattern: Kemper’s biography refuses the usual arc. A teenager kills two relatives, spends years confined, gets released, and then, years later, kills again. That gap is the part researchers kept coming back to.

Which official sources confirm key claims about Ed Kemper?

Court records and trial transcripts

• Santa Cruz County Superior Court holds the trial-court record for the 1973 proceedings (Santa Cruz County Superior Court (trial records)).
• The U.S. Justice Department’s NCJRS archive maintains an abstract of the Kemper case for researchers (OJP NCJRS).
• A jury found Kemper legally sane and convicted him on all eight counts.

The trial record is the primary text: charges, verdict, and sentence all flow from the November 1973 proceedings, and every later account — including this one — traces back to that court file.

FBI files and interviews

• Kemper gave extensive interviews to FBI Special Agents John E. Douglas and Robert K. Ressler while incarcerated.
• The conversations fed the FBI’s early profiling work (FBI).

“I wanted to see what it was like to have control over someone’s life and death.”

— Ed Kemper, describing his thoughts after murdering his mother, in a 1984 FBI interview, as documented by Oxygen (true-crime coverage)

To the FBI’s early profilers, Kemper was the rare subject who could articulate his own motives with unusual clarity — intelligence and self-awareness that made his interviews central to the development of profiling.

— Assessment attributed to FBI Special Agents John E. Douglas and Robert K. Ressler

Their conversations with Kemper are documented in the FBI’s famous-cases archive (FBI), and the case file remains a standard reference in true-crime and academic writing.

Prison records

• CDCR’s public inmate lookup is the official source for Kemper’s current location and custody status.
• Parole denials, including the 2024 hearing, are part of the same public record.

Together, those records describe a man who has been in state custody since April 1973, when he surrendered in Pueblo, Colorado. The paper trail is consistent from arrest to conviction to the present day.

What is still unclear or unverified about Ed Kemper?

What investigators have confirmed

• Kemper killed his grandparents, six young women, his mother, and a family friend — ten people in total.
• He surrendered voluntarily and confessed to the murders.
• He cooperated extensively with FBI profilers over many years.
• He has been denied parole multiple times and remains in prison.

What remains unverified

• Exact motivations for the 1964 killings of his grandparents are not fully established.
• Some details of his childhood, including certain abuse claims, lack independent verification.
• Forensic experts continue to debate the full extent of his psychological disorders.
• Authorities have found no evidence of additional victims beyond the confirmed deaths.
• Reported IQ figures vary by source — 131 in A&E’s coverage, 136 in other accounts.

The trade-off: Kemper’s candor made him invaluable to investigators, but it also means the psychological story we have is largely the one he chose to tell — and that is not the same as the whole truth.

What are the most common user questions on Ed Kemper?

Height, IQ, and physical characteristics

• Height: 6 ft 9 in (2.06 m).
• Reported IQ: 131 per A&E; 136 in other coverage.
• In interviews: described as articulate, precise, and self-aware.

Those two numbers — 6 ft 9 in and an IQ in the 130s — are a large part of why Kemper fascinated writers. He did not fit the stereotype of a disorganized killer, and that contrast drew the FBI’s attention.

Prison life and parole status

• Kemper remains in CDCR custody at California State Prison, Corcoran.
• Parole has been denied at multiple hearings, most recently in 2024.
• A&E’s coverage places him at the California Medical Facility during his incarceration.

Cultural appearances

• Cameron Britton played Kemper in Netflix’s ‘Mindhunter’.
• The Oxygen series ‘Kemper on Kemper’ built its episodes around his recorded interviews.
• Crime+Investigation UK maintains a detailed case file and timeline.

Few serial killers have been played on screen this often, and the reason is the same trait that made him useful to the FBI: he talked, at length, about what he did (Oxygen (true-crime coverage)).

What this means: the public questions about Kemper — height, IQ, parole, documentaries — circle the same fascination. People are not just asking what he did; they are asking how a man this intelligent became this dangerous.

The gap between the man the FBI interviewed and the monster of cable television is worth holding onto. Kemper’s own words helped build modern profiling, but those same words remain the primary evidence for parts of his story that can never be independently verified. For true-crime readers, the decision is clear: treat every retelling — including this one — as a starting point, and follow the source documents, or you risk mistaking a compelling narrative for a complete record.
