A Jury Convicted. A Family Still Grieves. The Trial of Karmelo Anthony Is Over — What Comes Next for Austin Metcalf's Case.

Austin Metcalf was 17 years old. A junior at Memorial High School in Frisco, Texas. The MVP linebacker on his football team. A twin, with a brother named Hunter who was standing right next to him when it happened.

On April 2, 2025, Austin went to a high school track meet at David Kuykendall Stadium. He did not come home.

On June 9, 2026 — fourteen months later — a Collin County jury delivered its verdict: Karmelo Anthony, now 19, was convicted of murder. The jury rejected his claim of self-defense. The case moved immediately to the sentencing phase.

This is a record of what the evidence showed, what both sides argued, and what comes next.

What Happened That Morning

The incident took place at approximately 10:00 a.m. during an 11-5A district championship track meet. A downpour had pushed athletes from multiple schools under available tents, including one belonging to Frisco Memorial.

According to the police report and trial testimony, Anthony entered the Memorial tent. Austin told him to leave. Anthony reached into his bag and said, “Touch me and see what happens.” Austin made physical contact — he pushed Anthony. Anthony pulled a pocket knife and stabbed Austin once in the chest, then ran from the stadium. Police apprehended Anthony within the stadium within minutes.

Austin Metcalf died from that single stab wound. His twin brother Hunter was present. He tried to help.

On arrest, Anthony reportedly told responding officers: “I’m not alleged, I did it” — and asked whether the situation could be considered self-defense and whether Metcalf was going to be okay.

More than 30 students and coaches witnessed the confrontation. Surveillance video of the incident and body camera footage from responding officers were both presented to the jury at trial.

The two had no prior relationship. They did not know each other.

The Trial: Nine Days in Collin County

The case was tried in Collin County District Court in McKinney, Texas, before Judge John Roach Jr. Jury selection began June 1, 2026, drawing 589 prospective jurors. A jury of 12, plus six alternates, was seated on June 3.

Anthony, who was 17 at the time of the offense, was tried as an adult. He was 19 at the time of trial.

The prosecution called more than 20 witnesses across five days, presenting the pocket knife, Anthony’s backpack, body camera footage, and surveillance video analyzed frame by frame. The state’s theory: Anthony issued a verbal threat before any physical contact, then used lethal force against someone who had responded to that threat with a shove.

Assistant District Attorney Bill Wirskye addressed the jury plainly in his closing: “This is not self-defense, folks. It’s murder.” The prosecution’s theory was that Anthony provoked the confrontation — that the verbal threat and the reach into the bag came before any physical contact from Austin, and that a shove does not justify a knife. “You do not get to meet a shove with a stab,” Wirskye told the jury, “especially if you provoke the shove.”

The defense called its own witnesses and presented a different frame. Defense attorney Mike Howard argued that Anthony, described as 5 feet 8 inches and approximately 130 pounds, faced a confrontation involving Austin and Hunter Metcalf — both described as approximately 6 feet 1 inch and around 215 pounds. Howard told the jury that his client made a split-second decision out of genuine fear after the first physical contact was made by Austin. A former teammate testified that Anthony appeared distraught immediately after the incident.

Anthony chose not to testify. Under the Fifth Amendment, he had no obligation to do so, and the jury was instructed that no inference could be drawn from that choice.

The defense rested on June 8. Closing arguments were delivered the morning of June 9. The jury began deliberations the same day and reached its verdict before the afternoon had ended.

The jury convicted Anthony of murder. The lesser charge of manslaughter — which the judge had added as an option, covering reckless rather than intentional conduct — was not chosen. The self-defense claim was rejected in full.

What Happens Next: The Sentencing Phase

Under Texas law, when a defendant is convicted of murder, the same jury that decided guilt then hears evidence during a separate punishment phase to determine the sentence. This is how Texas handles most serious felony cases — the jury does not simply hand the case to the judge. They stay on to decide the range.

For a first-degree felony murder conviction, the statutory range is 5 years to 99 years or life in prison. Because Anthony was a minor — 17 years old — at the time of the offense, the death penalty is constitutionally off the table.

The punishment phase was already underway shortly after the verdict was read. Anthony’s mother was reported to have been the first defense witness called in the sentencing presentation.

In the punishment phase, both sides present evidence relevant to the sentence: the defendant’s background, character, and mitigating circumstances from the defense; the harm caused and the victim’s family’s impact statement from the prosecution. The jury weighs that evidence and sets the sentence within the 5-to-life range.

Appeals: What Any Convicted Defendant Can Do

A guilty verdict does not end the legal process. Any defendant convicted of a felony in Texas has the right to appeal the conviction, and that right remains available to Anthony.

Appeals in Texas criminal cases go first to one of the state’s intermediate Courts of Appeals and potentially to the Texas Court of Criminal Appeals. Grounds can include claims that evidence was improperly admitted or excluded, that jury instructions were legally deficient, or that constitutional rights were violated at some point in the proceedings.

The verdict of June 9, 2026, may not be the final legal word in this case.

Austin Metcalf

He was a football MVP. He had a 4.0 GPA. He went to a track meet on a Wednesday morning in April, and he never made it to the finish line.

His twin brother Hunter was there when it happened. He stayed with Austin after the stabbing. That detail is in the record, and it belongs there.

A jury of twelve people listened to every piece of evidence in this case for more than a week. They heard from more than twenty witnesses. They saw the video. They came back with a verdict the same day deliberations began.

Whatever comes next in the sentencing phase and however the appeals process unfolds, those twelve people have now answered the question the law asked them to answer.

Austin Metcalf was 17. He deserved to come home from that track meet.
