Do you think Casey Anthony murdered her child?

I sort of think she did because it showed on her computer that she was looking up "neck breaking" and weird searches... Also that there was a fake nanny and she lied to her parents and everyone else saying that she was with the nanny and then the nanny supposely kidnapped her. And it as all a lie. Also when one of her freinds was on the stand talking about the little girl, something how she liked dora the explorer and just everything she like to do and how good she was.. and Casey didnt even cry. I was even getting teary eyed, how was her own mom now crying. I think something is seriously wrong with casey anthony.. I think shes guilty..
