A Texas Jury Sentenced a 19-Year-Old to 35 Years. His Mother Asked for One Thing.

On June 9, 2026, a Collin County jury took less than three hours to decide the fate of Karmelo Anthony.

The verdict — guilty of murder — came more than a year after a 30-second confrontation at a high school track meet ended with 17-year-old Austin Metcalf stabbed in the chest and pronounced dead at a nearby hospital before noon.

Karmelo, who was 17 at the time and is now 19, admitted to the stabbing. The question before the jury was never whether he did it. It was whether he had the legal right to.

They decided he didn’t.

What Happened at the Track Meet

April 2, 2025. Kuykendall Stadium in Frisco, Texas. More than a hundred student-athletes from eight high schools competing in a district track meet.

Karmelo Anthony, a student at Centennial High School, sat down inside a tent reserved for Memorial High School athletes. Austin Metcalf, a junior at Memorial, told him to leave.

What followed lasted less than half a minute.

Witnesses testified that Karmelo kept one hand inside his backpack and warned Austin: “Touch me and see what happens.” When Austin eventually shoved him, Karmelo stood and stabbed him once in the chest.

He then fled. A black knife with blood on it was later found in the bleachers.

Austin was taken to a hospital. He was pronounced dead at 10:53 a.m.

His twin brother Hunter had been there. Had watched it happen. Had pressed his hands over the wound trying to stop the bleeding.

“I grabbed his head and I looked in his eyes,” Hunter said later. “I just saw his soul leave, and it took my soul, too.”

The Trial

The defense argued self-defense. Attorney Mike Howard told jurors that the confrontation moved fast, that Karmelo believed he was cornered, that Austin had no legal right to use force against him even if he had every right to ask him to leave.

“There is no evidence Karmelo did anything but really think he was defending himself in that split second of chaos,” Howard said.

Prosecutors pushed back hard.

“He took a knife to a track meet,” said prosecutor Bill Wirskye. “He had a secret, he kept it hidden. He was the only one with a knife that day.”
