This is just a theory, because I really think That Caylee is deceased.
Before Caylee was born Casey was the "little princess" to her mom and dad. Then Caylee was born, and she became the beloved GD, adored by Cindy, and that made Casey jealous.
Cindy began to criticize Casey about not being a good Mom, maybe too much partying, and probably wasn't happy about Casey using her credit cards - also there was the 750.00 phone bill, plus many lies she probably caught her in.
Because of all the above Casey thought she would get even with Cindy by taking Caylee away for a while. She really wanted to get revenge on Cindy by depriving her of her GD. I think she may have had a friend, perhaps even the real Father (we aren't sure who this is), keep Caylee for
maybe a couple of months. Perhaps travelling out of State.
Since Caylee has been gone, Casey ended up in jail, and had no way to contact the person who has Caylee I think Baez knows this, and this BH coming in is all a ruse for them to get this child back, and keep Casey from being prosecuted.
The BH keeps saying whoever has Caylee should just drop her off somewhere - a Walgreens, etc. Why would he say that?
I hope my theory could be right - and Caylee is alive and comes home.
Casey may have just wanted to deprive her Mom of Caylee, and it all backfired, and then all the publicity and media coverage kept the person who has her from coming forward for fear of prosecution.
If the BH rescues Caylee, I may be right.
