Read the law.
North Carolina law states: If a defendant, who is a teacher, school administrator, student teacher, school safety officer, or coach, at any age
engages in intercourse or a sexual act with a victim who is a student, at any time during or after the time the defendant and victim were present together in the same school, but before the victim ceases to be a student, the defendant is guilty of a Class G felony, except when the defendant is lawfully married to the student.
I agree, there may be a good chance she didn't know the exact age of the guy(19 or 18) and was probably clueless to the law(that's not an excuse), but I almost guarantee she knew the guy through school. She's pretty cute and I'm sure it was probably some popular kid in the school.
If you read what the law is, it's obvious the lawmakers didn't want any faculty member involved sexually with any of their school's schools. That isn't too draconian considering the fluid nature which faculty is given responsibility over students. Plus every faculty member has some authority over the students.
Now here s more pictures.
