Why do you think he's such a saint? Don't you think grown, attractive, soft-spoken and kind men are also capable of child abuse? The prisons are full of them and thousands more are still out there free as the wind.
And what would he have to gain by killing the kid?
What did she have to gain? Again, it doesn't make sense that she would suddenly turn from being a loving, doting mother to I-think-I'll-kill-my-kid-so-I-can-party type of mother.
It wasn't internet searches on his computer about chloroform, breaking necks, etc......It was her computer.
Someone else could have used her computer.
It wasn't his car that smelled like a dead body.
I don't think the CSI ever determined that there was a dead body there; it was possibly something else.
It wasn't he who borrowed a shovel from their neighbor.
It wasn't he who lied about some mysterious nanny.
It wasn't he who took thecops to the supposed nanny's address, only to have them find nobody of that name ever lived there, nor was anybody ever matching the description she gave ever seen around there in all that time
It wasn't he who took cops to universal studios to try and perpetrate a lie about employment, in an attempt to concoct an aliby.
Again, with the rest of the above, if Casey and her parents were all trying to cover it up, any one of them could have made up those stories.
And now all of a sudden he's a child molester. But Casey had no problem leaving her daughter alone with him time and time again.
How often? Was that ever really determined or just hearsay?
