What a mess. I feel sorry for everyone involved in this story. I don’t know enough about the law to know if she has committed any crimes, under what laws? But if there’s a chance for the wrongly accused people to clear their reputations and get some compensation for their lives being disrupted then they should pursue it. The wife may not even understand she had done anything wrong and may not understand any penalties, and it certainly won’t cure her, so legal action probably wouldn’t have any affect on her thoughts or future behaviours. It’s purely for the benefit of the victims.
