A controversial behind-the-scenes agreement between prosecutors and defense attorneys has become a major focus of Karmelo Anthony’s request for a new trial, months after he was convicted in the fatal stabbing of 17-year-old Austin Metcalf.

Anthony, now 19, was sentenced to 35 years in prison after a Collin County jury found him guilty of murder in the April 2025 stabbing at a high school track meet in Frisco, Texas. His defense team now argues that unusual restrictions surrounding the trial affected his decision not to testify and prevented the jury from hearing potentially important information.

A Deal to Keep the Trial Focused
Before the original trial, prosecutors and defense attorneys reached what has been described as an informal “gentleman’s agreement.”

The arrangement was intended to keep potentially inflammatory information about both Anthony and Metcalf out of the proceedings so the jury could concentrate on what happened during the confrontation at the track meet.

The decision came amid enormous public attention surrounding the case, including racial tensions, protests, threats and harᴀssment directed toward people connected to both families. Prosecutors have argued that limiting the background evidence was necessary to prevent the trial from becoming even more volatile.

But the agreement has now become one of the central issues in Anthony’s effort to obtain a new trial.

Information About Anthony Was Kept From the Jury
During the recent hearing, prosecutors revealed previously undisclosed allegations concerning Anthony’s past.

Among the information were allegations that he had stalked a former girlfriend and sent her disturbing messages, including a pH๏τograph of a knife. Prosecutors also presented evidence of other threatening messages that had not been heard by the original jury.

One message reportedly involved a threat to “shoot the school up,” adding another troubling detail to the evidence now being examined during the post-conviction proceedings.

At the time of the original trial, however, the jury did not hear these allegations.

Information About Austin Metcalf Was Also Withheld
The agreement was not designed solely to protect Anthony.

Prosecutors and defense attorneys also agreed not to introduce potentially damaging information about Austin Metcalf and his twin brother, Hunter.

Newly revealed records have included allegations involving racist language, bullying, fights and other troubling incidents from Metcalf’s past. Those details were similarly kept away from the jury during the murder trial.

The unusual arrangement was intended to prevent the case from becoming a battle over the teenagers’ respective backgrounds rather than a determination of what happened underneath the tent at the track meet.

Why Anthony Says the Agreement Hurt His Defense
Anthony’s new attorneys argue that the agreement ultimately had a major impact on his consтιтutional right to defend himself.

Anthony had initially planned to testify in his own defense. But his attorneys say he changed his mind after concerns arose about what prosecutors might be permitted to ask him if he took the witness stand.

His defense now argues that the uncertainty surrounding the agreement undermined Anthony’s confidence in the process and contributed to his decision not to testify.

One of his former trial attorneys, Toby Shook, testified during the recent hearing that the defense believed Anthony would testify before the trial but that the situation changed as disagreements developed over the scope of the agreement.

Prosecutors Disagree
Prosecutors strongly dispute the suggestion that Anthony was prevented from testifying.

Collin County District Attorney Greg Willis has previously pointed to the trial transcript, arguing that the record does not support several of the defense’s claims about the agreement.

According to prosecutors, Anthony was given an opportunity to discuss his decision with his attorneys and family before ultimately telling the judge that he did not want to testify.

At the recent hearing, prosecutor Bill Wirskye likewise argued that there was never an agreement preventing Anthony from taking the stand.

The prosecution maintains that the restrictions were adopted because of extraordinary security concerns and the intense public reaction surrounding the case.

A New Judge Will Decide Anthony’s Fate
The legal battle has also resulted in a change of judges.

Judge John Roach, who presided over Anthony’s original trial, was removed from the post-conviction proceedings after Anthony’s attorneys argued that comments he made publicly about the guilty verdict demonstrated potential bias.

Judge Michael Chitty has now been ᴀssigned to consider Anthony’s request for a new trial.

The two-day hearing over the retrial request concluded Friday, August 21. A decision could come as soon as Saturday, August 22.

A Case Still Surrounded by Tension
The controversy surrounding the case extends far beyond the courtroom.

Anthony is Black, while Metcalf was white, and the case has become deeply entangled in racial tensions and public debate. Both families have faced harᴀssment and threats, while authorities have dealt with security concerns surrounding the proceedings.

The original agreement was partly an attempt to prevent those tensions from overwhelming the trial.

Now, ironically, the agreement itself has become a central reason Anthony says his conviction should be reconsidered.

For Anthony’s legal team, the question is whether the unusual restrictions and the circumstances surrounding his decision not to testify deprived him of a fair trial.

For prosecutors, the answer is very different: they maintain that Anthony received a fair proceeding and that the restrictions were necessary given the extraordinary circumstances surrounding the case.

The judge must now decide whether those issues are serious enough to warrant giving Anthony a second trial.
