I have been thinking about this all night. I don't think Casey will take a plea deal. Her history shows that she will go to great lengths to lie, steal, cheat and scam. Given this, and because the case has dragged on so long , the odds are still in her favor from a legal stand point only that there is enough reasonable doubt. This is an individual who thrives on attention, who will go to any extreme to deny even the simpiliest of lies. For Casey to take a plea deal, this would mean that she will be admitting since the conception and birth of her child was all a lie. Casey has the mind set that SHE is the victim, that SHE is the one who is being wronged, this mind set is engraved in her so strong that I don't see her admitting to anything.
The evidence from the Body Farm can be challenged, it's such new technology, and the thought of "air samples" from a vehicle that had sat for so long, with no evidence of who had access to it, much less Casey during this time period is going to be a problem. To me, LE going to the extreme of performing this test with the body farm tells me that they actually don't have hard core evidence of DNA.
Casey still also has a trick up her sleeve, her mother was the last known person to actually have Caylee, all evidence points to the Fathers Day visit as the last time there is any actual proof of the child's existence. Due to the behavior of both Cindy and George, there testimony of that day where they say Casey and Caylee walked out of the house can easily be twisted in a court room.
At some point, if there is strong enough evidence against her, Casey due to her nature, will turn on someone. It could be a family member, a friend, a boyfriend that was fired from the police department.
Common sense does actually not apply in a court room. Hard evidence does, and I don't see where there is evidence or proof Casey killed her daughter.. Caseys psychological profile suggest someone that will deny any knowledge of wrong doing to the extreme. She does not have to take the stand, which will make the case harder for the prosecution to make there case. While all the circumstantial evidence clearly points to Casey killing her child and covering it up, I don't see evidence beyond a shadow of a doubt that needs to be presented in a court of law.
The release of the documents with all the interviews of her friends, show a giddy willingness to testify on behalf of the prosecution. This will be used against them by the defense. The most damming evidence is the interview of Casey herself, but yet she still maintains in these hard to believe interviews that she did not killer daughter and as of now, there is no evidence that this child is dead. Each friend that provided a statement can be cross examined in such a way that there credibility will be called into question. The fact that her own "boyfriend" was a police officer and lied, was fired will be a huge psychological factor in this case. Police officers lie! The testimony of the two (I believe it was two) independent wittiness that insist they saw Caylee after the date the prosecution insists will be the date of death is a problem.
This is a high profile case, a dream for any attorney who wants to feed there ego and get free publicity. There is still a chance that a high profile attorney will jump in and take this case. I keep thinking of the OJ case, the Jon Bona case, the Eisenberg case. All had the same factors as this case.
Unless this child's body is found, and evidence it obtained from the body, the items on the child, or at the site of where the child was buried, I see a problem with this case. I realize that I did not provide an example of every single item that can be called into question. I tried to concentrate on the most serious flaws of this case, and that is DNA evidence, a body and a motive.
