To me she sounded as if she was on the verge of flipping out at the LE.
Casey - "OMG. I already TOLD YOU, SHES GONE!!! I spent a month looking for her, didnt find her, NOW FORGET ABOUT IT! If i couldnt find her, WHAT MAKES YOU THINK YOU WILL??? If i say Zanny the Nanny has her, then ZANNY THE NANNY HAS HER. END OF STORY. I have to go now, I have a pasta dinner at TonE's waiting for me. GOOD-BYE."
Now that Caylee is gone from her life, she feels like all her problems are solved. To her, the worst thing in the world was having to look after that little girl. Jail is preferable. The only time we will see emotion is if/when she gets the death penalty.
I cant wait for this fiasco to end. I am not a praying person but every night for the last week, I have asked God, the universe, or whatever is out there to PLEASE lead someone to that poor wee girl. The cold-hearted monster is just LOVING the fact that she is the only one who has that info and that the whole world is hanging on her every word...
The tapes prove beyond of a doubt that she thinks she is smarter than the LE and the rest of the world. I just CANT WAIT under the day she finally realises that it is all about to come crashing down around her, then we will see the mask slip.
End of rant
ETA- I think during this interview it is very clear that up until that point Casey had been no where, doing nothing, to look for Caylee. It sounded to me as if she was beginning her "investigations" with her "backward way" of "round about" looking in the Universal office late at night. I am suprised they didnt ask her how come she had not been there previously to talk to the security guard and check the turnstyle cam... seriously, the girl is just plain stupid. She thinks that she had those guys in the palm of her hand - WRONG AGAIN PRINCESS.
