I don't see how someone that is purportedly normal snaps and decides to take out that many innocent people. What if he wasn't the real shooter? What if he's shot and left behind so that the real sniper can just make his escape? If his room adjoined any another rooms, they should be looking at the adjoining room occupants, and studying the hallway cam footage for the comings and goings from those rooms. I hope they are already looking into this. I just don't want someone that is capable of this level of evil to still be breathing.
