I don't have the answer to your question, but would venture a guess that Ms. Sims has gotten so much flak from that interview she gave on Joy Behar's show, that she's staying away from the media henceforth.
I agree Dottie probably got flak from how she failed to answer the babysitting question with a yes or no. I bet Baez or Mason told her off after seeing that interview. Also the next day Dottie had troubling answer some of the questions Ryan Smith asked her on In Session.
I have said this before, I think Baez and Mason are media savvy. They both know how to answer questions for most part in a good tension free manner. Sims comes off as the type of person who is overly confident/smug when she isn't being asked questions by the media. She was bouncing up and down like a fool at that restaurant on the day of the verdict. I think she went on the Behar show with the attitude that she was smarter or could outsmart on Joy when trying to defend Casey. But she failed, her emotions on her face showed her grimacing and she at times look liked she wanted to crap her pants.
The Orlando media made a big thing about the Sims' tv appearances and on twitter there were several people tweeting Joy and giving her props for grilling Sims with that question. Sims was laughed at by many. Marcia Clark and Joy laughed at her later on after the babysitting question. JVM, Mike G. and Nancy Grace also brought up her failure to answer the question.
I bet Baez has banned Dottie from being the media for good regarding Casey's case. I wonder if Casey has seen the Joy Behar clip.
