Who is the mystery man (mystery man to us) that LEO nabbed in the forestry area adjacent to the school. The man who was, was said to have said "I didn't do this" or something like that. Where is this man?
Did he immediately profess his innocence or was he told about it? Did he know what happened at the school BEFORE he was told about it?
I'm guessing he was told, just because the alternate explanations are to weird and unsettling.
It turned out to be a parent of one of the kids who was bringing stuff to the school.
