Believe it or not, in NJ (and a few other states), that's not true.
But, the precedents apparently apply to them kicking her out of the house before she finishes her education (which can include college). And, it's only been used in cases where the parents have split up -- i.e. making the absentee father pay for tuition.
Since she left the house on her own, and the parents are still together, the precedents apparently didn't apply.
I can’t imagine any college taking her after all this publicity. She has already been accepted by a few colleges but those acceptance letters are contingent on a number of things, including subsequent behavior. Not unheard of for colleges to void the acceptance.
