Wannabe NBC producer contends that Angela Corey would be alarmed that the attorneys didn't know where Zimmerman was; but Zimmerman had called her office.
BTW, Zimmerman's new lawyer suggested that it was quite unusual for a pair of lawyers to announce they weren't going to represent Zimmerman any more, and then talk to the press for another hour.
Maybe Angela Corey was concerned that she was looking at the possibility of a murder conviction overturned on grounds of incompetent legal defense.
The attorneys statements essentially say that Zimmerman had gone rogue and they do not know where he is or what he is doing (since he is not following their instructions). They realized they needed to absolve themselves of responsibility for his actions.
It is not a coincidence that Corey arrested Zimmerman exactly one day after this statement was made.
Corey filed charges, and Zimmerman voluntarily surrendered the same day, with new competent counsel.
Zimmerman realized he was getting crap representation, and probably called Corey saying he was willing to testify before a grand jury, or to talk to her investigators, or surrender if she charged him with a crime.
Remember, he didn't have a lawyer when he talked to the police the night of the shooting or the day after when he did the walk through.
She told him he needed a lawyer, and likely that he needed a good one, that she was not willing to risk getting a conviction overturned based on ineffective legal representation.
While it is unlikely that she would make a comment on Sonner specifically, that someone would talk to the press for an hour about their former client really brings into question their professional ethics.
