We don't know, but the only thing she has said that I am aware of was the phone call home where she says 'I saw your Cameo on TV' to CA in a sarcastic tone.. CA then says "Which one, I have done four?"
Yeah, she was concerned about "you don`t know what my involvement is in stuff"? But I got the idea that she wanted them to keep up the idea of a live Caylee, but not sure. Anyway I think it was the facts and Caseys own conduct that convicted her in the media.
