This is where my thinking is. Deep down did they know the truth from the beginning, I think so. But I notice the no visits and they are being rather silent on the 'she's still alive, or Casey didn't do it' stories. It could be because of the document dump or it's because the lawyer told them, 'Look, this is the deal, you need to pull your heads out of your you-know-whats and face what's going on, or else.'
Personally, George's interview about 'not wanting to believe someone you brought into this world could do something like this', something to that effect, told me he knows what the truth is. He might not have wanted to face it at that time, but he knows.
It's funny that just yesterday their attorney BC said they believe *zanny* hurt the baby. I realize in terms of this case 24 hours is a huge amount of time but still -- I'll take a wait and see on that.
And btw, if I never hear the word Zanny again in this lifetime that's fine with me.
