Well, the good news is that I'm not the only one dealing with this and it has gon up the chain of command, so to speak, so someone way above my pay grade is in touch with the appropriate authorities. The hard part is that I have had some direct conversations with the person (albeit all online/email/chat/etc.) and it has me a bit freaked out. I know I've done everything I can to try to help; now I just have to hope for the best. That's not a position I like being in.
