Do you think Casey Anthony Killed her own child (caylee) or do you think she is covering up for someone else? ?

I think that she did it, alone, and that after she had committed the murder and disposed of Caylee's body that her mother and father found out what happened and I believe they lied to the police and provided the fake hairbrush to throw the police off and to cover for Casey to protect her. I fully expect Cindy and Casey's dad to be hauled in on accessory after the fact charges, obstruction of justice, tampering of evidence-something along those lines. As for the discrepancy in time 2 weeks or 31 days, I think she just got caught up in her lies and messed up on the dates.
