I am listening to Nancy Grace. They are playing the tapes of the interrogation of Casey. She certainly sounds convincing about this babysitter that she claims disappeared with Caylee. If she isn't telling the truth, she certainly is a good liar. She comes up with lots of details when asked questions. The thing is though, as I understand it, she didn't contact the police and report Caylee missing because she feared for Caylee's life and apparently thought the rest of her family was in danger. But, now that Caylee has been found dead, I would think she would tell why she was afraid. Her attorney has said though that once her story is told in court people will understand the why of it all. We may not hear about any further test results until the trial. I guess her parents believe her story, or claim they do.
