Now the man was certain that this thing had killed his sister, that he had tried to tell the police, but they would not listen. Next he had tried to tell his priest, but the priest turned him away when he saw that the thing was following him now - oh, thats right, I forgot about that - it can only get you if you tell someone else about it, or you saw it kill someone else.

Apparently his mother and father had immediately called his aunt about this when it happened. They were found in the morning, skinned and dismembered. Their bodies were covered in tiny, child-like handprints.
His aunt was really drunk the night before, and had told him about that. He told me this story early in the morning today at school, before the cops arrived. His aunt had been murdered that night. I called him later that night, and he told me that he was being chased by someone, and now they were knocking on his door. I told him to stop shitting me.
