    Paul John Knowles is an American serial killer linked to the deaths of at least 18 people. He recorded a chilling "kill tape" confession detailing his murders and carried out one of the deadliest multi-state killing sprees in American history in just a matter of months. Known as the "Casanova Killer" because of his conventionally handsome appearance, Paul murdered men, women, and children, sexually assaulted many of his victims, and even attempted to commit necrophilia. In Part 1, we explore his troubled upbringing and the events that transformed him into one of America's most prolific serial killers.

    EP189: Five Wives and a False Prophet: Nathan Chasing Horse and "The Circle" Cult

    24/06/2026 | 1h 13 mins.
    Trigger Warning: This episode contains discussions of domestic abuse and child SA.  Please listen with caution.

    Five wives. A revered spiritual leader. A celebrated actor whose role in Dances with Wolves made him famous around the world. For decades, Nathan Chasing Horse cultivated an image as a respected medicine man and cultural figure - but behind the scenes was a sprawling web of sexual abuse, manipulation, and control. Nathan Chasing Horse used his spiritual authority to convince followers that he possessed supernatural powers, that he could see the future, and that young girls were destined to become his wives. What emerged was a story that sounds less like a religious community and more like a cult: one built on fear, obedience, and the unchecked power of a man who was treated as untouchable — until survivors finally spoke out and brought his reign of abuse crashing down.

    EP 188: Greenbrier Ghost: The Spectral Snitch (ft. Kaelyn Moore of Heart Starts Pounding)

    17/06/2026 | 1h 24 mins.
    FOLLOW/SUBSCRIBE to Psychopedia wherever you are listening!This week I was joined by special guest Kaelyn Moore of Heart Starts Pounding and Clues podcasts!In 1897, in a small town in West Virginia, a 23-year-old woman named Elva Zona Heaster Shue was found dead under mysterious circumstances and quickly laid to rest. Her tragic story might have ended there, if not for what happened next. According to local legend, Zona returned from the grave and appeared to her mother night after night to describe in chilling, accurate detail how her husband had murdered her and broken her neck.  What followed was an investigation, an exhumation, and one of the strangest murder trials in American history. Because this remains the only known case in American legal history in which the testimony of a ghost helped send a killer to prison.Find Heart Starts Pounding! @heartstartspounding
