Zak, Nick and Aaron rent an RV and drive through the night to reach the remote town of Rawlins, WY, to investigate one of their darkest haunts to date: The Wyoming Frontier Prison. From 1901-1981, Wyoming's first state penitentiary served as a virtual death house for as many as 200 inmates. While some of these deaths were the result of state-sanctioned executions, others died from harsh living conditions and the infamously brutal violence that took place behind its cold walls.
