About this episode
The episode discusses the murder of Willie Nickell and the controversial trial of Tom Horn in Wyoming.
In 1901, fourteen-year-old Willie Nickell was shot and killed near his family’s ranch in southeastern Wyoming. Suspicion eventually settled on Tom Horn, former Apache War scout, Pinkerton detective, and one of the most feared men connected to the Wyoming range wars. But more than a century later, historians still debate whether the state truly proved he committed the murder. Source Materials Ball, Larry D.
