She has never taken part in the card swaps. I do have what might be her last name, but am not sure of her address. I wouldn't want her to feel like we were persecuting her by having the police show up with no warning. I'll try emailing her again, and will let you all know if I hear back. That said, if she's gotten herself out of the situation, she may be somewhere with no Internet access right now, or have been warned against posting for her own safety. Like I said, I'll let you all know if I hear anything.
