Jack is average height. He wears glasses, has dark brown hair, which is not short but not long. Outside of school he wears a sweatshirt to make sure he isn't noticed.

People would say he is insane, which make him look like the killer (which he isn't). He feels like everyone doesn't trust him and always wants to hide from social issues. He wants people to trust him and will work really hard to do so. He also doesn't trust the police to find the killer and is investigating this murder himself. If there is someone he trusts enough who wants to help him he will let them.

No equipment on him, but owns a sword and a gun, which are in his closet.

No interesting story behind him.
