The sequestration violations by defense witness Donnelly may provide an opportunity. Given the events up until this point, if the shoe was on the other foot and it was a prosecution witness involved, the defense would be screaming bloody murder. Don’t be surprised if she declares a mistrial tomorrow.
What was the “sequestration violation” issue? The cited video mentioned that it would be decided tomorrow morning, but the issue was not described.
Also, earlier on this thread asked what data from the phone was withheld by the prosecution. The video showed the defense complaining, but did not provide information on what it was.
I doubt that. For a mistrial to be justified, the testimony of the witness would have to have such a potential impact on the jury that the mere hearing of the testimony would irreparably prejudice the jury. Donnelly basically just testified that the screams on the Lauer 911 tape were GZ, just like about a dozen other witnesses.
Now, if Donnelly had gotten on the stand and said he saw the fight and had a picture of it showing TM throwing the first punch, but the prosecution would not allow him to show it - that would probably justify a mistrial. But him basically repeating what many other witnesses had already testified to would not seem to be the game changer needed to justify a mistrial.
