No jacket and she has her hair in the scraggly pony tail, neither is a good look for her if she does plan to testify.
Vinnie P said that the shirt she is wearing is similar to the one she wore when she answered the charges about the thefts (2010) and that maybe that is telling about whether she will testify.
I think Casey would have had a much better chance if they just came up in the beginning with accidental drowning under HER care. And then she panicked and it became an "accident gone bad." I also think she will be convicted but won't get death. Their Defense is pretty bad and things just don't add up.
