Its been reported that the woman was working after hours in the school and was by herself.
That is the same as I have read. I do not think the 15 yr old was a student.
So she was asking for it, huh?
It sounds like she may have been teaching in alternative education. Our school had that program for kids who could not behave, play nice during regular school hours. They asked me to teach in this program and I said no way in hell. I didn't think there was enough money to be made being in a class alone with 5-9 very bad, morally bankrupt kids (usually male, sorry folks, all white, rural school, and color had nothing to do with it.) I always thought that should be strictly done by the big, male teachers.
