Here's the story in the news (from 2000).....
ACLU of Oklahoma Files Federal Lawsuit on Behalf of Student Accused of "Hexing" a Teacher | American Civil Liberties Union
Thanks for providing a source that is worth our time and more impartial and objective.
The deeper story here is that it is one of (sadly) many cases of religious discrimination that have occurred in public schools against minority religions. Given our culture doesn't take spellcraft seriously, that's all we can make this about in terms of the court of law. At most it could be taken as a warning sign that the situation might escalate, because if the student really was Wiccan, she would have been acting in a fashion that violated her own religion. Acting against one's own sense of virtue is a big red flag that something is amiss, and in this case, it was likely the crap treatment she was receiving at the school because of her minority religion status. But it's hard to say. The article is old, the full story is not presented here, and any given situation is always quite complex.
