No reason was given for closure of the school, where according to testimony at the polygamy trial, boys were told to treat girls as "dangerous snakes."
My theory as to why they closed it: Girls and boys were starting to feel unnatural attractions for each other (don't even get me started about the same-sex attractions...), and the girls needed to be got out of there post haste so that they could be readied for "voluntary" marriage to whoever the woman-hating cult leader is right now. Maybe the boys too, I don't know.
