How many years in prison can a late 30's woman in north carolina for assault and battery of a 14 yearold girl.?

She can spend most of the rest of her life in prison for that. It's aggravated assault, which is a felony with a very long (I believe 20-40 year) prison term. The other girl will do some time as well, first as a juvenile (and I'm assuming this girl is the same age as your daughter) and then in an adult facility, depending on what the judge rules. And it'll look good for your daughter, since so many people were there to see what happened and can place both of them there.
