More than two months after a Texas jury convicted Karmelo Anthony in the fatal stabbing of 17-year-old Austin Metcalf, the courtroom battle is beginning again.

This time, however, the central question is no longer simply what happened beneath a team tent at a Frisco track meet.

Anthony’s new attorneys are challenging how his trial was conducted — and asking the court for something far more consequential:

A new trial.

The 19-year-old was convicted of murder in June 2026 and sentenced to 35 years in prison for the April 2, 2025, stabbing of Metcalf during a rain-delayed high school track meet at Kuykendall Stadium in Frisco, Texas.

Anthony admitted that he stabbed Metcalf but maintained that he acted in self-defense.

The jury rejected that argument.

One day after his conviction, Anthony filed notice that he intended to appeal.

Now, his new legal team is pursuing a broader post-trial challenge that could determine whether the conviction remains intact or whether the case eventually returns to a courtroom.

Two Hearings Could Shape What Happens Next
Anthony is scheduled to return to court for two important hearings.

The first is set for August 19.

His attorneys will ask that State District Judge John Roach Jr., who presided over the original trial, be removed from handling the remaining post-trial proceedings.

Judge Sid Harle is scheduled to hear that request.

Then, on August 20, Anthony’s attorneys are expected to present their arguments supporting a motion for a new trial.

The two requests are separate.

Removing Roach would not automatically give Anthony another trial.

Likewise, merely filing a motion for a new trial does not mean his conviction has been overturned.

Anthony remains convicted and continues serving his 35-year sentence while the legal process unfolds.

Why Does the Defense Want the Judge Removed?
Anthony’s new attorneys have focused partly on comments Roach made publicly after the verdict.

In post-trial interviews, the judge discussed aspects of the proceedings, his decisions and the jury’s verdict.

The defense argues those comments create questions about whether Roach can remain impartial while considering challenges to a trial over which he personally presided.

His attorneys therefore want another judge to handle the post-trial proceedings.

But obtaining recusal requires more than simply disagreeing with a judge’s rulings.

North Texas criminal defense attorney Josh Healy, who is not involved in Anthony’s case, told NBC DFW that the defense will need to establish the type of bias required under the applicable legal standard.

Whether Anthony’s attorneys can meet that threshold will be one of the central questions at the August 19 hearing.

The New-Trial Motion Goes Much Further
The request for a new trial raises several different issues.

Anthony’s attorneys argue that restrictions on public access to the courtroom violated his constitutional right to a public trial.

During the highly publicized proceedings, courtroom space was limited and strict rules governed access by spectators and members of the media.

The defense now contends those restrictions went too far.

But another argument has attracted even greater attention.

It involves an informal pretrial understanding between prosecutors and Anthony’s original defense team.

Court filings describe what has been characterized as a “gentleman’s agreement” or handshake deal concerning evidence that both sides would avoid introducing.

The arrangement was designed to keep the trial focused primarily on what happened beneath the tent where Anthony and Metcalf confronted each other.

Under the understanding, certain evidence concerning Anthony’s background would remain outside the case.

In return, the defense would also avoid introducing certain character evidence involving Metcalf and his twin brother.

But according to Anthony’s former lead attorney, Mike Howard, the defense eventually concluded that prosecutors were no longer honoring the agreement as originally understood.

That allegedly changed the defense strategy dramatically.

Why Anthony Never Testified
Perhaps the most significant consequence involved Anthony himself.

He did not testify at his trial.

According to an affidavit from Howard included with the new-trial motion, the dispute over the pretrial agreement affected the decision to keep Anthony off the witness stand.

The defense feared that if Anthony testified, prosecutors could potentially introduce damaging material that attorneys had previously believed would remain excluded.

Howard says the issue also affected other evidence the defense had considered presenting.

Anthony’s new legal team now argues that the dispute interfered with his ability to fully present his self-defense case.

Prosecutors are expected to challenge that interpretation.

The court will have to determine whether what occurred represented ordinary strategic decision-making during a criminal trial — or whether it created a legal problem serious enough to justify setting aside the conviction.

A Case That Has Been Closely Watched From the Beginning
The legal battle comes after a case that generated enormous attention long before Anthony’s trial began.

Both Anthony and Metcalf were 17 when they encountered each other during the April 2025 track meet.

Rain had interrupted the competition, forcing athletes to seek shelter beneath team tents.

An argument developed after Metcalf confronted Anthony about being under a tent designated for another school.

Witnesses described a confrontation that escalated quickly.

Anthony pulled a knife and stabbed Metcalf once.

Metcalf died despite efforts to save him.

Anthony was arrested and later told police he had acted in self-defense.

That became the central argument at trial.

His attorneys maintained that Anthony believed he was threatened and reacted during a rapidly escalating confrontation.

Prosecutors argued that the use of deadly force was unjustified.

After hearing the evidence, the jury convicted Anthony of murder on June 9.

The same jury sentenced him to 35 years in prison.

A New Legal Team Takes Over
Following the conviction, a new group of attorneys joined Anthony’s case to handle the post-trial and appellate process.

Their strategy has expanded beyond simply arguing that the jury reached the wrong conclusion.

They are challenging elements of the proceedings themselves.

The public-access restrictions, the disputed pretrial agreement, Anthony’s ability to present his defense and Roach’s continued involvement are now all under scrutiny.

Legal experts caution that obtaining a new trial after a jury conviction is difficult.

The defense must do more than identify decisions it dislikes.

It must establish errors serious enough to justify disturbing the verdict.

That is what makes the upcoming hearings significant.

For the first time since Anthony was sentenced, his attorneys will have an opportunity to develop those arguments before a judge.

The Verdict Still Stands
Despite growing attention surrounding Anthony’s appeal, the legal status of the case has not changed.

Anthony’s murder conviction has not been overturned.

A new trial has not been granted.

And Judge Roach has not yet been removed from the post-trial proceedings.

Those questions are now heading back to court.

On August 19, the fight will center on who should oversee the next stage.

On August 20, attention is expected to turn directly toward whether Anthony should receive another trial.

Whatever happens, those hearings are unlikely to represent the final chapter.

If the new-trial request fails, Anthony’s attorneys can continue pursuing issues through the appellate process.

If the defense succeeds, one of North Texas’ most closely watched criminal cases could move toward an extraordinary outcome — another trial over the confrontation that occurred beneath a track-meet tent more than a year ago.

For now, however, the jury’s decision remains in place.

Karmelo Anthony is serving a 35-year sentence.

And the next major decision about his case is only days away.
