My sense is that there are a few other things that would make a mother panic and try to cover up. Allowing a child to die in a car seat in the heat of the day is one. Allowing a child to drown when she should have been watched is another. Allowing a child to be abused by someone is another. All of these would be reasons to cover up. None of them are capital murder cases. All of them are prosecutable with charges ranging from negligence to complicity.
We had the trial in our area of a lady who let her child die in a hot car. She was savaged by just about everybody.
Did those happen to Caylee Anderson. Don’t know
I agree, panic and fear cause people to do some rather irrational things. It sounds to me like that whole family was rather prone to rash behavior anyway.
