Well techinically he didn't kill the prom queen she got away. Also title kinda gives the story away. Also how can it be a kid with mental illness if he just dissapered. You tried to make a mental illness story and then the ending ruined that. You even labeled it as mental illness. Scarefactor: 4. Thrillfactor: 5. Twists: 3. Storytelling: 3. I feel like this was story in favor of giving students guns. Will he we ever hear from the "killer" again. I hope not considering that is the most generic name, even the butcher is a less generic name. Poor old Andy.
Overall Score: 4-6
