I've read the depositions.
From them, I have learned that:
a) GA may have molested Caylee, after which he murdered her in the pool. Afterward, Caylee was found dead, Casey was blamed, and George said he would "take care of it".
Casey then spent 31 days in denial, wanting/hoping that her daughter was still alive, and within that time period weaved a complex web of lies to explain Caylee's disappearance to everyone who asked. George kept quiet about Caylee's death, and Casey never told anyone the truth about what really happened the day Caylee died--except through her DT at trial.
b) Casey was subjected to repeated sexual abuse by GA that she never told her mother about, which he eventually stopped. Casey never told her mother that her father sexually abused her.
c) LA fondled Casey's breasts until she finally told him to stop. She told her mother, who didn't believe her and called her a *advertiser censored*.
d) Dr. Danziger had a great deal of difficulty reconciling Casey's affect and her seemingly unblemished childhood and adolescence with the severity of the sexual abuse she described, the severity of the crime she was charged with, her description of how her daughter was killed, and her ongoing incarceration. His "puzzlement" came about because the story didn't fit the overall nature of the person.
==========================================
Casey could have been sexually abused by the males in the household. It is not uncommon for sexual abuse to continue unchecked with the effective concurrence of the adult female in the household who also lives in denial and does not step up to protect her daughter. Casey's ability to "compartmentalize" these events to allow her to function relatively normally to the outside world isn't unprecedented. It seems unlikely, but it isn't impossible.
Why would a young woman who had what appeared to be a well-adjusted life suddenly begin to compulsively lie and steal in the midst of the murder of her daughter?
How could she remain lost in 31 days of denial knowing that Caylee was dead, and that her father may have killed her?
Is it just as possible that the 31 days of denial were obscuring the fact that she killed Caylee herself?
=======================
Her story of George's complicity in Caylee's death makes absolutely no sense to me, but at some level, the jury bought it.
There are so many riddles in this case, it absolutely boggles the mind.
I don't think we will ever know the truth, and I think the jury felt the same way. That is why Casey walked. She's impenetrable, unsolvable even--and that has proven to be a very dangerous talent.
