I guess I kind of forgot one small thing. It doesn't appear the schools around here really check up on volunteer coaches. It's a decision by the head coach I think and since they aren't being paid, the school just lets the head coach do what he needs to do. I could be wrong, but that is how it seems.
The only reason it was discovered who he was by the school who suggested he look elsewhere was because the head coach's wife had personal knowledge and put two and two together. This is the same school district who sent him a letter from their attorney telling him not to come back on the property of the elementary school or he would be arrested, after he yelled at and threatened the principal and another teacher. But since there was no check done, it took a while to put two and two together.
