Johnny brought his father’s shotgun to school for show and tell. The gun accidentally discharged, blowing off Billy's head as he sat in his desk at the front of the class. The laughter of the children quickly turned to screams of excitement or horror. This accident foreshadowed events thirty years later when he walked into his office and shot eight coworkers with a rifle. Afterwards, he sat at his desk, tidied his papers, and then shot himself in the temple with a .38 special. But this time, it was not an accident.
