Residents of Fremont County, CO, have learned the hard way that when you invite evil in, it stays. VALLEY OF THE DAMNED is a six-part series examining seven murders that rocked the beautiful, desolate mountain region of Fremont County, deep in the Colorado Rockies. This vast, inhospitable region of Southern Colorado is known as Prison Valley because it is home to 15 prisons including America's only Federal Supermax. This valley has more correctional facilities than any other in the US, so in a town where you're surrounded by prisons, how does someone get away with murder? The brand-new series VALLEY OF THE DAMNED premieres Tuesday, September 3 at 10/9c only on Investigation Discovery (ID).

Prison Valley is no stranger to violent inhabitants - housed within prison walls are some of the most infamous criminals, including drug lord El Chapo and Unabomber Ted Kaczynski. But outside those walls, the valley itself is a safe community where residents look out for one another. For the first time ever, family, police, witnesses, lawyers and journalists come together to discuss the murders that occurred in their town - a place that is ultimately the monstrous force that ties all of these murders together.

Each of the six episodes tell the raw and emotional stories of twisted, psychologically complex homicides that all took place in Prison Valley; 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 divorce. In the premiere episode, police must work to connect the seemingly unrelated murders of Dominos' pizza delivery driver Nathan Leon and Colorado Prisons Chief Tom Clements. Investigators go from having virtually no information to being swamped by a myriad of possible suspects with a motive to kill, and a suspect pool that spans Colorado's 20,000 former prison inmates.
