Edmund Kemper III grew up in a home defined by fear, humiliation, and emotional violence long before he became known as “The Co-Ed Killer.” Standing 6’9’’ with a calm, almost gentle demeanor, Kemper hid a darkness that even seasoned investigators struggled to comprehend. In this episode, we dive deep into his early life, the fractured family that shaped him, and the warning signs that appeared years before his first murder.

We follow Kemper’s path from a troubled childhood, to the shocking killings of his grandparents, to the series of murders that terrorized California’s college communities in the 1970s. Through his chilling confessions, manipulative intelligence, and unsettling cooperation with law enforcement, Kemper became one of the most disturbing figures in American criminal history.

This episode breaks down:

• Kemper’s childhood and early psychological patterns

• His murders at age 15

• The escalation into the Co-Ed Killer era

• How he evaded suspicion despite inserting himself into police circles

• His relationship with his mother and the final crimes that ended his spree

• His eerie calmness as he turned himself in and described his actions in detail

Israel Keyes is one of the most calculated, unpredictable, and terrifying serial offenders in American history. In this episode, we walk through his life from childhood to his final days in custody — and trace the crimes he thought he’d buried forever.

You’ll hear how Keyes built a double life: a quiet father and construction worker on the surface, but a roaming predator who traveled the country, buried “kill kits,” chose victims at random, and struck wherever he felt opportunity. We cover the abduction of 18-year-old Samantha Koenig in Anchorage, his cross-country movements, his hidden caches, the disturbing tapes from his interrogations, and the long-suspected crimes that investigators still believe he committed.

This episode follows the full timeline — his early life, military years, the Koenig case, the Currier double homicide, his years of planning, his interrogation strategy, and what investigators uncovered after his death. No dramatics, no embellishment — just the verified, documented story of one of the most elusive serial killers the FBI has ever investigated.

A man who seemed to appear and disappear at will. He crept into homes, watched victims for days, terrorized entire communities, and evaded police across multiple counties. He was first known as the Visalia Ransacker, then the East Area Rapist, then the Original Night Stalker — and eventually, the world came to know him as the Golden State Killer.

This episode follows the full evolution of his crimes: the escalation from burglaries to assaults to murder, the fear that gripped neighborhoods, the survivors who refused to stay silent, and the investigative failures that allowed him to continue unchecked. Finally, we trace the scientific breakthrough that changed everything: the use of genetic genealogy to identify Joseph James DeAngelo, a former police officer hiding in plain sight.

Told through detailed research and narrative storytelling, this is the story of how one of America’s most elusive predators was finally unmasked after more than four decades of terror.

In this episode of Three Voices One Crime, we examine one of the most disturbing criminal cases in American history: David Parker Ray, the man known as the “Toy Box Killer.” Operating out of a modified, soundproof trailer in Truth or Consequences, New Mexico, Ray spent years abducting and torturing women while hiding in plain sight.

We walk through Ray’s early background, his long-term patterns of violence, and his partnership with Cindy Hendy—who helped lure and restrain victims inside the “toy box.” This episode focuses on the 1999 escape of survivor Cynthia Vigil, whose bravery finally exposed Ray’s operation and led investigators to uncover the torture chamber filled with restraints, devices, and detailed audio recordings describing how Ray planned to harm his victims.

We break down the full investigative timeline, the evidence recovered from the trailer, the court testimony, the known victims, and why authorities believe Ray may have had many more victims who were never identified. This episode honors the survivors whose strength brought the truth to light while presenting a clear, chronological narrative of the case.

Between 1982 and 1998, dozens of young women vanished from the streets of King County, Washington. Their disappearances weren’t random — they were the work of a quiet, unremarkable man named Gary Leon Ridgway, a truck-painter who blended into the suburbs so well that even those closest to him never suspected the truth.

In this episode, we break down the real Green River investigation:

the victims who fought to survive, the families who demanded answers, the detectives who spent decades chasing a ghost, and the shocking 2001 breakthrough that finally revealed the identity of the most prolific serial killer in American history.

Using court records, FBI behavioral files, and verified timelines, we walk through Ridgway’s methods, his motives, his confessions, and the massive task of identifying his victims — one that continues to this day.

This is the story of the Green River Killer.

The Cleveland Strangler: Anthony Sowell

In this episode, Three Voices One Crime uncovers the chilling story of Anthony Sowell — a convicted serial killer whose crimes went unnoticed for years on the east side of Cleveland. Between 2007 and 2009, women vanished from the neighborhood surrounding Sowell’s Imperial Avenue home, while police missed multiple opportunities to intervene. When the truth finally emerged, authorities discovered nearly a dozen bodies hidden inside the house, revealing one of the most devastating investigative failures in Ohio history.

This episode explores Sowell’s early life, the escalation of his violence, the systemic breakdowns that allowed him to continue killing, the survivors who tried to warn police, and the intense community outrage that followed. Through timelines, public records, and contemporary reporting, we reconstruct the investigation from the first signs of danger to Sowell’s conviction and death.
