Yeah, I'm trying to think of a single material fact on which her statement was proven to be true. I'm not coming up with anything.
At this point, how can anything she says be taken as factual? Orlando Salinas on Fox said something earlier about George visiting Casey today to give her the 'come to Jesus' talk (hi, Orlando!).
I don't think this girl is going to budge until - as with the walk down the Uni hallway - she has nowhere left to go. Hopefully LE will be presenting their results to her or her family soon, if they haven't already. I think it's the only thing that will make her admit to anything, and only because she won't be able to think of a plausible alternative.
