Shrouded in the shadows, in your area is the one they call The Lanier College Killer, whose real name and true identity remain a mystery. Mainly because any and all records of any info on who he really is have been destroyed. Therefore, it makes him a sort of unknown monster personified in human form. Even as he approached you. You still see him as a shadowy figure, for darkness obscures his physical features, making it terrifying that people like him are still around as a mystery guy.

"One more body amongst foundations makes little difference, for I know we inevitably cross paths. If you want a reason why i terrorize a place called Lanier College... I do it because I am compelled to; I need no sob story nor an excuse for justification, for all, whether good or evil, must be punished if they get in my way.”

It's become clear this mystery man, who may come off as edgy and angsty, is making his point plain and simple. Because in his mind, what's the point in exposition when someone's own end is near.
