A previously undisclosed agreement between prosecutors and Karmelo Anthony’s defense attorneys has emerged as a major issue in the legal battle over whether the Texas teenager should receive a new trial.
Anthony, now 19, was convicted in June 2026 of first-degree murder in connection with the fatal stabbing of 17-year-old Austin Metcalf during a high school track meet in Frisco, Texas, in April 2025. A Collin County jury later sentenced Anthony to 35 years in prison.
Now, court filings are providing new details about what Anthony’s attorneys have described as an informal “gentleman’s agreement” reached with prosecutors before and during the trial — and why the defense believes what happened with that agreement affected Anthony’s decision not to testify.
What Was the “Gentleman’s Agreement”?
According to court documents cited by the New York Post, the two sides had agreed to keep potentially prejudicial information about both Anthony and Metcalf away from the jury.
The arrangement was intended to keep the trial focused largely on what happened during the confrontation itself rather than allowing either side to introduce broader character evidence or information about the teenagers’ histories.
Among the information reportedly kept out was evidence concerning Anthony’s school disciplinary history and cellphone records. The defense, meanwhile, refrained from introducing certain information involving Anthony’s family background and character evidence concerning Metcalf and his twin brother.
The agreement was informal rather than a conventional written deal approved by the court — a detail that has now become significant.
Defense Says the Situation Influenced Anthony’s Decision Not to Testify
Anthony maintained that he acted in self-defense after the confrontation with Metcalf escalated.
But Anthony never took the witness stand to personally explain his version of events to the jury.
His former lead trial attorney, Mike Howard, later claimed in an affidavit that concerns surrounding the prosecution’s handling of the informal agreement contributed to the decision to keep Anthony off the stand.
Anthony’s new legal team has now cited the dispute as one of several reasons it believes he should receive another trial.
However, newly released trial transcripts have complicated that argument.
According to reporting based on those transcripts, Howard told the judge during the trial that prosecutors had upheld their side of the agreement before Anthony made his final decision about testifying.
The transcripts also reportedly indicate Anthony had at least 30 minutes to consider whether to testify, conflicting with a later claim that he was given only about 10 minutes.
Lead prosecutor Bill Wirskye has argued that the official trial record does not support many of the allegations subsequently raised about what occurred.
That disagreement could now become important as a court considers Anthony’s request for a new trial.
Anthony’s New Attorneys Are Challenging More Than the Agreement
The “gentleman’s agreement” is only one part of a broader post-trial challenge.
Anthony’s appellate attorneys are also seeking the recusal of Judge John Roach, who presided over the original trial.
The defense alleges that public comments Roach made following the verdict created questions about whether he could remain impartial while considering Anthony’s post-trial motions.
When a reporter asked whether the jury had reached the correct decision, Roach reportedly answered, “Yeah, they did.”
Anthony’s attorneys argue those remarks are significant because the same judge could otherwise be responsible for considering arguments challenging the fairness of the trial he oversaw.
Two Critical Court Dates Are Approaching
The case is now approaching another potentially decisive moment.
According to Collin County’s official court information, a hearing on the request to remove Judge Roach is scheduled for August 19, 2026.
A separate hearing concerning Anthony’s request for a new trial is scheduled for August 20.
Those proceedings could determine whether Anthony’s 35-year sentence and conviction remain intact or whether his legal team gets an opportunity to push the case toward another trial.
For a case that appeared to reach its conclusion with the June verdict, the newly publicized details surrounding the informal agreement have opened another legal chapter.
The central question now is not whether the agreement existed, but whether anything surrounding that agreement — along with the defense’s other allegations — was serious enough to deprive Anthony of a fair trial.
The court will soon have to decide.
