Pardo's job was to protect the Warden from Colorado State inmates, his own correctional officers should they turn on him and any Chimera that might stumble on the mine. Pardo and his collegue Tom Olsen also sexually assaulted the female prisoners of the mine during weapon checks.
On September 26th, 1953, Inmate Susan Farley and Correctional Officer Red Cooper informed Pardo, Olsen and Warden Brewster of a collapse tunnel in Tunnel 4 which left another correctional officer, Atkins, dead. Pardo was shocked, though only because Atkins owed him a box of .22s. Later that day, Farley kills Warden Brewster, who had attempted to rape her, and Pardo is killed by a shot in the chest as he rushes into the Warden's office to see what the commotion is.
