Karmelo Anthony's legal team is arguing the entire process of his murder trial violated his constitutional rights, and are asking for a brand-new trial.
They also asked for Judge John Roach to be removed from post-trial hearings because of his alleged bias.
In court filings, Anthony’s lawyers said the judge made comments to news reporters following the trial and "expressed personal opinions about the propriety and correctness of the jury's verdict, the fairness of the trial and the correctness of the judge's own rulings during the trial."
When a reporter asked Roach if the jury got it right, he responded, "Yeah, they did." The judge then reportedly explained himself and talked about his rulings.
The defense argued that the judge’s personal views suggest his probable decision on a motion for a new trial.
What's new:
A different Collin County judge will hold a hearing on Aug. 19 to on the motion to replace Judge Roach.
The next day, the defense team will argue their motion for a new trial.
