From my personal suggestion, I would prefer if she punished by asking her to carryout a community service since she is a first time offender. This would only be possible if she was evaluated in a mental facility to check her mental state of mind is in order.
It could be that, she was mentally stressed hence the reason, <em>she was behaving irrationally. If it was so, she should be checked into mental institution where she would be treated firstly before any other further punishment could be carried out on her.</em>
