Aug 10, 2026 · 51m
Summary
Hosts Keith and his co-host discuss the case of Heriberto Seda, the "New York Zodiac Killer," who terrorized Brooklyn in the early 1990s. They detail Seda’s failed military aspirations, his obsession with serial killers, and his use of an untraceable zip gun to shoot multiple victims. The episode highlights how police missed connecting his crimes due to a lack of ballistic evidence and a temporary lull in his attacks. Despite being arrested with his weapon in 1994, Seda was released, allowing him to continue his spree until his eventual capture.
