"I don't really know what to think. It's so unlike her, I'm basically flabbergasted. In a way it makes me feel like I don't even know her, heh."
Wow! I missed this thread. You never know even people you live with and think you know very well. This life is unpredictable sometimes.
If she had the money to buy the markers, and if she's telling the truth, then she may have done it because of a feeling of entitlement or an impulse. Usually, that kind of behaviour doesn't stop so fast. Nevertheless, I hope she never makes this mistake again.
If I were you, I wouldn't be worrying about fines. I would worry about how she could ever get her record expunged, in the event that she pleads guilty or gets convicted (which will likely happen). Since it's normally classified as a misdemeanour, she'll not be able to expunge it. (I may be wrong, though.) The sad part is, this will haunt her for the rest of her life, especially if she pursues any careers that would require working with or around kids. Furthermore, she may get rejected silently or in letters because of her background; the employers won't tell her, though. Nevermind! I see she isn't a minor. This was an extremely bad timing. . . .
To be honest, unless this is really a unique case with extenuating circumstance, you will not find a lawyer willing to take this to the end. They'll likely tell you her to plead guilty . . . not to waste the court's time, etc.
Best of luck to her. Keep us updated!
