The Convicts, consisting of Sam Franklin, Reginald Jenkins, and Miguel Sanchez, are Dead Rising psychopaths involved in the mission Prisoners.
They are three escaped convicts who ride around in a stolen military Jeep with a mounted Heavy Machine Gun. They occupy Leisure Park, attacking survivors and zombies alike.
When defeated, Frank can take control of their Humvee and drive it around Leisure Park. The gun is also detachable and serves as a powerful firearm. This will also allow you to unlock the Carjacker achievement and the Prisoner Outfit.
Unlike the rest of the psychopaths, the convicts respawn each night at midnight. However, they will not respawn at the start of Case 8-1.
