'Valley Of The Damned': New ID Series Investigates 7 Unsolved Murders In Colorado Town

Residents of Fremont County, Colorado, have learned the hard way that when you invite evil in, it stays.

This vast, inhospitable region of Southern Colorado is known as "Prison Valley" because it is home to 15 high-security prisons including America's only Federal Supermax.

The new Investigation Discovery series Valley Of The Damned examines seven local mysteries — including the 2006 murder of 17-year-old Candace Hiltz.

The six-episode series takes a deep dive into murders that rocked the beautiful, desolate region in the Colorado Rockies known as "Prison Valley."

The region is a place of contradictions: The prison has housed some of the most infamous criminals in the world, including drug lord El Chapo and Unabomber Ted Kaczynski. But outside prison walls, the valley is a safe community where residents look out for one another.

The series features interviews with family, police, witnesses, lawyers, and journalists as they come together to discuss murders that occurred in their town. It explores everything from the carefully planned assassination of Prison Valley's Head of Corrections to an infamous Colorado love-triangle murder case and a charismatic Jehovah's Witness who chose murder over a divorce.

Watch the Valley Of The Damned premiere on Tuesday, September 3 at 10/9c only on Investigation Discovery!
