Has anyone ever read "lamb to the slaughter"? It's a short story about a woman who kills her husband with a leg of lamb, and then proceeds to put the lamb in the oven to cook it for dinner. When the police come to investigate, she is entirely calm because she knows that they need the murder weapon to solve the crime. In the end, she feeds the lamb to the police officers - no more weapon to find.
I think that the Anthony's are 100% sure that Caylee's body will not be found. They are way too confident, they know where she is, and they are not even slightly worried that the body will be found. I don't think that George and Cindy were involved from the start, but they know where she is now. It makes me wonder if she is, in fact, buried somewhere very close where they can keep a close eye on her. It's just so strange to me the way these people behave.
