The drowning theory by the Defense was to create reasonable doubt. (I certainly don't know if it was true or not, because it wasn't proven) The state put on their case and were the ones that had to prove murder, and what they thought had happened. I know they, the state thought they had a slam dunk case, but it just didn't happen that way in the court room.
It didn't need to be proven, just beyond "A" reasonable doubt". IMO, having ANY chloroform in your trunk along with a stain, suspected grave wax on napkins taken from a trash bag from that SAME trunk, "duct", not "duck" tape proven to be attached to the child's skull and proven to have come from the A's, the pooh blanket, the laundry bag that also was proven to have come from the A's home, the testimony of the neighbor having seen KC backed into the garage on 6/17/08, borrowing the shovel the same day from that same neighbor, the sticker silhouette on said duct tape, the 31 days w/o reporting your own child missing and then getting the date wrong (first reported to go missing on 6/9/08, not 6/16/08), the lies upon lies.
You say she has been punished for the lying....small consequence since they all culminated in the timeframe that Caylee went missing and she will continue to suffer for the lies she told to others with law suits coming her way, so she's far from done.
You are totally correct that the child died, not by herself, but how?
At the very least, she should have gotten the lesser charge of abuse and neglect if they couldn't conclude that the duct tape or the chloroform did it. They had proof through testimony and science that there was a dead body in KC's trunk and the only one that was dead was Caylee. LDB tried to get the message across all those times when KC stated Caylee was with the "nanny", "where was Caylee"? The jury never got it. They did not listen to what she was trying to tell them. She was in the trunk of that car. So, why isn't that regarded as child neglect and abuse?
There wasn't enough evidence, for me, to prove murder, beyond a reasonable doubt. Did KC lie, yes, and she was convicted of that. Did she make chloroform? Not Proven. Did SHE use Duck Tape? not proven.(it wasn't proven that she used duck tape) There are a lot of ways she could have died.
However she died, it was at the hands of her mother. By KC's own admission she was the last person Caylee was "seen" with. Whether she just gave her a drug, a pill, something in a sippy cup, whatever, she wanted her out of her hair so she could go enjoy her social activities. "Nanny" was the trunk and that's where I believe she died. Most of the time, the DT witnesses ended up being witnesses for the State because they were either wrong in their answers or uninformed and that was brought out by the prosecutors, wo why didn't the jury pick all this apart and recognize that?
The theory that had to be considered to prosecute KC is what the state/prosecution gave to the jury.
IMO, they had more than enough to see beyond a reasonable doubt that KC was guilty of at least the lesser charge. I feel she got away with the ultimate crime but, maybe someday if Caylee's "clothes that we've never found" will tell the full story.
