The Incredible Survival Tale of Shasta Groene - Part 1 - Jospeh Duncan III

The Predator the System Released — Part 1 In 2005, the name Joseph Edward Duncan III shocked the nation after a brutal crime in northern Idaho led to one of the most disturbing manhunts in modern true-crime history. But the story didn’t begin in Idaho. Long before the Groene family murders made headlines, Duncan had already been arrested, convicted, and imprisoned for violent crimes against children. His criminal history stretched back decades, marked by repeated warnings, prison sentences, psychological evaluations, and opportunities where the system could have intervened. In Part 1 of this four-part series, we trace the timeline of Joseph Duncan’s life before 2005 — from his early years and first violent crime in Washington State to the murders investigators would later link to him in King County, and the federal prison sentence that followed. By the time Duncan crossed into northern Idaho in the spring of 2005, the warning signs behind him stretched back more than twenty years. This episode examines the predator the system released. ⸻ Listener discretion advised. ⸻ #ShadowsInThePines #TrueCrimePodcast #JosephDuncan #PNWCrime #TrueCrimeCommunity
