We are on the same page, my dear FRiend. I could be totally wrong about everything. I post what related info I can find and offer my 'thoughts'. Your comments prompt me to do the research, and I learn from it. I don't have all the answers. Wish I did.
As I have told others many times in the past, when I am right, I learn nothing. It is only when I find I am wrong that I learn something new.
Now you have prompted me to read up on this case as well - if you see more info and think of it, ping me please - I do think you are right that this new info on the FIL probably means his fantasies about the DIL were just that - in his head.
