No, I don't think he was a witness but I think they narrowed down the last time Casey heard and/or saw Caylee alive.<quoted text>
But if you believe Casey didn't know Caylee was dead until the remains were found, then Jose Baez cannot KNOW anything more than information he was given from an undisclosed source, who was probably also inflating the swimming pool drowning theory as well.
Unless you're now suggesting Jose Baez was a witness to the child's death?
I don't think it is the date the public at large thinks it is.
It certainly wasn't the morning of June 16, 2008 in the presence of George Anthony.
It's Casey's story to tell, isn't it?
