But what is "what she did to her"? That's what wasn't proven. Did Caylee die in an accident and Casey try to cover it up? Did Casey intentionally kill her daughter? Did Casey flip-out and kill Caylee in a fit of anger? Did Caylee drown and Casey agree to cover it up to protect someone else? The prosecution didn't prove *what* happened, so she can't be found guilty of even manslaughter.
Why did the jury ignore DNA evidence of Caylee’s post-mortem hair found in the trunk of her mothers car that she abandoned? The woman was her mother, who’s job it was to look after her, maintain her safety and know her whereabouts at all times. To abrogate her responsibility in doing this for a full month while partying it up and allow her to turn up dead without giving truthful answers as to her whereabouts is reason enough for a child endangerment conviction had the child been found alive. But since she died we’re supposed to have a higher standard of evidence?
