My vote/version of what I think happened probably isn't a popular one. I kind of see things a little differently. I do think she's guilty.
However, I do think she loved Caylee based on what we've heard from others, how we saw the way she acted with her in videos, how they both seemed to be happy in pictures, how she (Casey) had lots of Caylee related things all over her walls and room, etc.
Having said that, I think Caylee's death was an accident. HOW, I don't know. I just don't think she plotted and planned to kill her out of maliciousness or something sinister. I think an accident occurred and she panicked and tried to hide the body.
Of course her behavior after the fact is still a little strange and doesn't add up to what I think. Meaning, even if it were an accident and she felt bad, you'd think that she'd at least still feel bad, guilty, appear sad, depressed, SOMETHING along those lines. And yet we know that she seemed happy, normal, etc. So, that I don't get.
But, if I were on the jury I guess I'd have to find her Guilty of First Degree Murder based on how I see things. JMO
