Also, I am on the other threads to say that if the guilty part(ies) are ever found, if there are any, they will be persons who have been in the VDs' home with their knowledge and consent, and probably in connection with swinging/sex.
I've always wondered if something like this wasn't at the heart of the Jon Benet Ramsey case.
