I don't have much advice, I just wanted you to know I feel for you. What a difficult situation. It seems to me that all you can do is give her the GI Rights number and ignore anymore requests for anything. She's an adult and you can't get in any trouble on her behalf, especially if she won't help herself. I can understand your not wanting to be involved in her apprehension, but don't get involved in her crime either.
What a shame. I'm so sorry you have to deal with this. It's more pain than a parent can take.
