I think George is just now grasping that Caylee is dead. I don't think it has anything to do with his daughter just yet. He became so invested in the "hope" that she was still alive that he actually flew out to California to be on Larry King and discuss this with his wife. The very next day, her remains are found. Dec. 11.
But the remains are not confirmed for a couple of weeks. Christmas time. So, the A's can still "hope" that it is someone else. Then, even after the confirmation, there is much legal wrangling about a second autopsy. It still hasn't hit him yet. It is the second week of Jan. They are in "seclusion."
No real news for 2 weeks. They are not busy. They are not on TV. They are not following up on "caylee sightings." Nothing is occupying them anymore. This is when it is hitting him, that Caylee is not coming back.
So he goes off on his own. Its not about who done it. Its about his beloved grandaughter is actually dead. God bless him.
