First of all, if the defense atty knows that Casey killed Caylee, he CANNOT ask her on the stand if she did it, what happened, etc.... Most probably he has NOT discussed whether she did it or not, but instead has operated on the idea that she didn't do it. Otherwise, if he knows for a fact that she did it then he is knowingly allowing her to lie on the stand - and she can go to jail for that, but he almost certainly would lose his license to practice law. So while they may all KNOW that she did it, he CANNOT ask the question OR allow her to answer it if anyone else asks around him. He also cannot go to the parents and say "we all know she did it, but we are going to do x,y,z and throw you under the bus to confuse and distract people."
Second, I just read a sort of overview of the facts and WOW, either Casey is an incredible liar or the parents and bro are complete fools. She worked at Universal studios in 2005 but did not return to the job after caylee was born in 2008! so for almost three YEARS she lied about going to a job and getting paid for doing it!!! If she can do that, she can and will do anything - absolutely ANYTHING to anyone for no real reason at all.
Plus the nanny was NOT the only person she lied about. She said she had 2 friends from Universal - Jeffrey Hopkins and Juliette Lewis. She actually told people that the nanny also watched Jeffrey Hopkins' son. They could find NO record of a Jeffrey Hopkins, a Juliette Lewis OR a son of Hopkins'!!!!! How in the world do you invent so many people - and what a disgusting thing to do when supposedly you are frantic about your toddler's disappearance??!!!??!!
It is incredible how she claimed to be searching so hard for Caylee, to be so upset and to not let ANY of her friends, the people who see her every day (because she was not living iwth her parents at this time, so they were not in her daily life but she was NOT living a solitary life, Know what I mean??) know she is even a little upset because the child is gone? I find that claim to be totally nonsense - no way any mother who is even slightly fit doesn't let people know the child is gone or dead. If, as claimed, the baby drowned at the parents' home and the dad knew, how did she handle those weeks with-o anyone at all seeing her even a little upset over it?
I think most, if not all, states have an automatic appeal if you get the death penalty - it is just part of the process. And if they didn't want that for Casey maybe they should have taken custody away from her - clearly they knew there were problems long before she went missing. Otherwise the mother would not have been calling her an unfit parent. Plus, you do NOT get to be that good at lying with-o a TON of practice. the parents HAD to know she was a complete and total liar so they HAD to be suspicious of what was going on when they first were not allowed to see or speak to her. NO WAY a partier good time girl like Casey goes a month with-o dumping the kid on her parents for free babysitting. Nannies have to be PAID - and she didn't have a job. I wonder how she got the money from her supposed job at Universal that didn't exist? You cannot go that long on nothing - I am thinking prostitution of some kind, either outright or mooching off "boyfriends" and leaving when the money runs out or they stop being willing to fund her lifestyle. Cause partying is NOT NOT NOT cheap.
