    Episode 137: Shasta Groene and Joseph Edward Duncan a Survivor's Tale Part One

    When Shasta Groene was eight years old, she survived 47 days in the forest with the serial killer and apex child predator who’d killed her family and abducted her: Joseph Edward Duncan. Her tale of survival in the hands of this brutal monster is beyond harrowing and disturbing, but it is also a tale of resilience, hope, and, eventually, healing. Listener discretion is strongly advised.   MURDER COASTER PODCAST Hosted by Christa Carmen and Matthew Brockmeyer Website: www.murdercoasterpodcast.com Facebook: Murder Coaster Instagram: https://www.instagram.com/murdercoasterpodcast/   Creepy Amusement Park theme by Brandon Fiechter and Derek Fiechter, used by permission and with many thanks.   REFERENCES: Out of the Woods: A Girl, a Killer, and a Lifelong Struggle to Find the Way Home by Gregg Olsen.

    Episode 133: The New York Zodiac "Eddie" Hariberto Seda

    “Eddie” Heriberto Seda was a serial killer with an uncanny resemblance to Eddie Munster, who was obsessed with sorcery, necromancy, astronomy, magic and spells, and who envisioned himself as a continuation of the infamous Zodiac Killer who’d terrorized San Francisco twenty years earlier. Like the original Zodiac Killer, Eddie wrote bizarre letters to the press and police, plunging New York into a state of panic and fear, becoming known as the New York Zodiac. It is an utterly bizarre story, with a conclusion as wild as it gets.
