I found this blog on the web and thought it was good information. It is written by two detectives from Texas and they answer questions about what "could" be going on behind the scenes. Like "what do you think happened to Caylee, do investigators have as little to go on as it appears, what does Casey's behavior indicate to you, etc. Very interesting.
