Xavier is predator catcher. He poses as a little girl trying to lore predators. Well, when they do show up he kills them in brutal ways. Well forward to now he has many of them in his basement bloodied and crying in agony. He didn't care. Someone was supposed to show up but he accidentally left a head on the couch and he chased the man outside swinging with a knife. You were a mail man in which the man screaming was running in your direction. You recognized Xavier, hell the whole neighborhood knew him.
