We really don't know much but I've read the literature on these folks, so here's some points that might play out.

1. There may be some underlying mental illness.
2. The shooter may be suicidial.
3. He is making a statement with his shooting.
4. It could be revenge for a slight, a conspiratorial fantasy or some other delusion.
5. He wants to die a warrior's death rather than an isolated suicide.
6. Or he wants the arrest and subsequent ability to make a statement or enjoy the pain he inflicted.
7. He may have studied the other rampage sites like Columbine or Aurora which channeled his goals and gave him vicarious reinforcement in fantasy form as he planned his action and maybe his death. He fantasizes the aftermath. That is way most experts want us to down play the horror shots and interviews with victims. Every crying mom or dad reinforces the fantasy of the next one of these killers.

All these are just suggestions. So far we don't have a targeted attack at specific people like an Amy Bishop.

He may or may not have surfaced to some authorities. We will see, if the signs were missed or ignored.
