Thinking on this last night, it really hit me, Casey is confident that Caylee won't be found. TES is in town, the Body Hunters are in town, the FBI is searching, not to mention local LE ......ALL THIS MANPOWER and yet Casey doesn't seem to be the least bit fazed or scared. Casey didn't accept the immunity deal and just spends her days in her room on the computer (which she has to know is being traced) and baking brownies. The only time I've seen her upset was when she was first incarcerated and denied a lower bail. Whatever she did with Caylee, she's confident about it. If I were in her shoes, with all the manpower looking for Caylee, I'd be scared and take a deal. Of course Trenton Duckett hasn't ever been found (like so many others) so it is possible Caylee's body will never be found, seems like Casey is banking on it.
