Yesterday, George lost his temper with reporters going into the visit with Casey, and when he and Cindy came out from the visit, both avoided the reporter's questions. One reporter said that George was seen wiping tears from his eyes.
Then this morning, Cindy's meeting with the detectives, parking at the rear of the building away from reporters. LE seem to help Cindy by getting her car for her and parking it nearer the back entrance, and Cindy hugged the female LE before getting into the car. It doesn't sound like the meeing lasted very long.
Something has changed, and my guess is that Casey may have said something that cast doubt on her original story.
