“”Who is Christina? I am not familiar with the name. Also, when was this recording made?””
I don’t think any explanation was given as to who she was when the tape was played in the trial nor was she ever called as a witness. I don’t know if she was a friend of Casey’s or a friend of George and Cindy. The call from jail to the Anthony house was made after Casey was first arrested after the detectives had questioned her at Universal. The charges for that arrest are part of the seven charges in this trial.
Christina is Lee Anthony's fiancé. The recording was made while Casey was in jail, I think the first time, before she was bailed out.
