She is an adult now but remains unrepentant

She is brainwashed, Dave. She was an immature teen when she went. She has lived for years amongst extremists. She did make a bad choice in going there but once she was there she had no choice but to stay. She has suffered the most tragic loss anyone could ever imagine, the loss of a child. Not once but twice. I would give her the benefit of the doubt and say her unrepentance is not callousness but the result of something akin to shell shock.

I didn't know that the child's father was Dutch though so good point there. Is he still alive and living in Holland? If so, yes, let him help.
