Gang Central

Go behind bars at the Denver County Jail, where the officers are charged with transferring gangbangers to a brand-new facility across town. Witness how some prisoners have manipulated their dangerously outdated surroundings to make homemade weapons. Visit the mental health unit as employees struggle to reform a career criminal with severe mental illness. And go inside with deputies as they face an accused triple murderer who discovered a way to keep his maximum-security cell from locking.
