My :twocents: All of the evidence that I've seen in this case points to only one person who could have killed this child: Casey Anthony. Yes, her family is weird and dysfunctional, but IMO Casey is the one responsible for the death and attempted cover-up of the death of Caylee. Casey dug her own grave when she took off for 31 days (and probably would have been gone for much longer had Cindy not tracked her down), had a dead body in her car, which prompted her to ultimately ditch the car, spent the 31 days partying, entering a hot body contest and getting a tattoo that read "the beautiful life". This isn't a witch hunt, IMO. The evidence points to one person only-the defendant. She's been given a fair trial IMO.
I agree with you-her parents were neglectful in their enabling of Casey's lies throughout the years; but Casey is the one responsible for Caylee's death.
