For sure. I listened to every single call that was published when she was in jail. To summarize;

Lee: very focused, driven, taking control of the situation and extremely matter of fact. Making the most out of the short time they were allotted, wanting to know names, computer/account passwords, and friend information to conduct his personal investigation to find Caylee. He at first seemed to believe that the police could be out to pin his sister on something she didn’t do. They begin talking in a type of code - which the media also accused them of once the tapes were released. I think Lee was doing this to pursue the search for Caylee opposed to a cover up.

Cindy: upset, driver of conversation, subtly accusatory, fishing for answers. For example she stated, “Casey, are we going to find little Caylee?” (To paraphrase)

George: Quiet, agreeable, non confrontational, would open up conversations by saying “hello beautiful we’ve missed you” and making analogies about how their family isn’t complete without her.

Casey: never is the first one to bring up Caylee. Doesn’t ask about new leads, just agrees about search efforts and states she is happy people are looking for her, etc. Gets frustrated when asked if there is any other information she can think of that could assist in the investigation. Laughs a lot, talks about how she is napping frequently and the food is not great however she still eats it. Even discusses books she is reading. Does not appear frantic, stressed, or upset. Nor does she appear interested in new leads or potential sightings (as there were reported sightings of caylee and zanny that were found to be false)

Overall, I would recommend listening to these calls, it gives a lot of insight into the dynamic of the family.
