wow I just watched a part of the interview of Greta with the grandparents. You should see how George is looking at Cindi. He is extremely angry and fed up with her. Look at this photo

and watch the section of the interview where Cindy speaks about the announcement of the official charges. The way George looks at her speaks volumes.
I don't think George helped to cover anything. He was the first one who took LE on the side that very same night they called 911 and told them they should look closer to his own daughter. And I don't think Cindy helped with any crime either. But I do think she was and still the driving force ENABLING CASEY'S LIES AND BEHAVIOR FOR YEARS. And she excuses her even now....even now that they are facing this tragedy.
