It is not much different from the storys of other families who have experienced a loved one in cult activity, but we felt it was time to say something publically.
What a heartbreaking story. Thank you for going public with it.
In a case like your son's, where it appears he could not leave even if he wanted to, I am wondering whether a guardianship proceeding could help. Perhaps this would at least require he show up in court and be evaluated by a psychologist.
