The Murder of Peggy Carr: Poisoned Coca-Cola and the Neighbor Next Door

The Murder of Peggy Carr: Poisoned Coca-Cola and the Neighbor Next Door

Author: Moms and Mysteries Podcast August 27, 2026 Duration: 1:06:03
In the fall of 1988, Peggy Carr, her son Duane Dubberly, and her stepson Travis Carr became violently ill inside their rural Florida home. The symptoms were strange and terrifying: severe nerve pain, numbness, weakness, trouble walking, and eventually, hair loss. Doctors discovered they had been exposed to thallium, a rare and deadly heavy metal. The source was even more disturbing. Someone had carefully opened glass bottles of Coca-Cola, added thallium, resealed the caps, and placed the bottles inside the Carr home. Peggy died after spending more than four months in a coma. Six other members of the household were also poisoned, including a young child. The investigation pointed to George Trepal, the Carr family's next-door neighbor. He had chemistry knowledge, a history of disputes with the family, and a bottle-capping machine in his garage. We cover the poisoning, the undercover operation that gave investigators access to Trepal's home, the trial, and the later questions about FBI testimony that did not overturn his conviction.

Between school drop-offs and grocery runs, Mandy and Melissa found a shared obsession with the unanswered questions lurking in the shadows. Moms and Mysteries: A True Crime Podcast is the result: a conversation that feels like sitting at a kitchen table with two friends who are deeply curious about the human condition. Their perspective is uniquely grounded, examining each story not just for its shock value, but for the societal threads and personal tragedies that weave it together. You’ll hear them discuss everything from the strangely specific weirdness of a Florida crime to a globally known cold case, always with a blend of empathy and a dash of necessary, dark humor. This isn't a clinical report; it's a twice-weekly deep dive fueled by a lifelong fascination with mysteries, both big and small. The tone is warm, the research is thorough, and the conversation is the kind you get hooked on. New episodes of this true crime podcast arrive every Tuesday and Thursday, ready to be your companion during a commute or while folding laundry. They’ve been asking "how did this happen?" since they were kids, and now they’re pulling up a chair for you to join that ongoing, compelling discussion.
