Crowbar: The Killings of Wendell Graves

Innocent Wendell Graves grows up to become a murderous psychopath after seeing his parents slaughtered by a masked maniac. After barely escaping the clutches if the killer, Wendell retreats to his aunt's secluded farmhouse for over a decade. During that time, his aunt convinces him that anyone who dares come near his old family home is trespassing, and that they should be ruthlessly butchered. Wielding a sharpened crowbar - the same weapon used to kill his parents -- Wendell sets out to punish anyone and everyone who dares set foot in his house.
