Silo Killer 1 & 2

A group of college kids decide to spend their weekend camping in the Arizona desert. They have all the supplies they need and are fully prepared to rough it in the barren plains. The one thing they didn't prepare for was a mad dog killer who plans on killing them one by one and stacking their dead carcasses into an abandoned grain silo. Everyone that sets foot in the desert that weekend seems to meet a bloody fate as even the sheriff and a couple of organized crime's finest henchmen are no match for the psychotic butcher. The standard question of "who" and "why" seem to be irrelevant as the answers remain a mystery and the body count increases.
