A Texas high school track meet ended with a verdict that will follow two families for the rest of their lives. Karmelo Anthony, now 19, was sentenced to 35 years in prison after a Collin County jury found him guilty of murder in the fatal stabbing of 17-year-old Austin Metcalf during a Frisco ISD track meet in April 2025.
The sentence closed one chapter in a case that shook parents, students, coaches, and a wider community, still trying to understand how an ordinary school event turned deadly. The stabbing happened at Kuykendall Stadium in Frisco, where athletes from multiple schools had gathered for a district track competition. What should have been a day of races, team tents, cheering families, and teenage ambition became a courtroom case watched far beyond North Texas.
Austin Metcalf, a junior at Memorial High School, was stabbed once in the chest after a confrontation under a school team tent. Anthony, who attended Centennial High School, admitted to the stabbing but maintained that he acted in self-defense. Prosecutors rejected that explanation, telling jurors the killing was not justified.
A School Event Became a Crime Scene

The track meet began like many school competitions do, with athletes moving between races, coaches managing teams, and students crowding under tents as the weather moved through the area. Rain pushed students toward cover, and that is where the confrontation began.
Reports from the trial said the dispute started after Anthony was under a tent used by Memorial High School athletes. Witnesses testified that Austin and others asked him to leave. What happened next became the center of the trial, with the prosecution and defense offering sharply different views of the same brief but devastating encounter.
The defense argued that Anthony felt threatened after Austin pushed him and acted out of fear. Prosecutors argued that the response was wildly disproportionate and that Anthony had other choices before using a knife. Jurors heard testimony from students, investigators, medical experts, and witnesses who had been at the stadium that day.
The fact that the victim and defendant were both teenagers made the case feel even heavier. This was not a late-night street fight or a planned attack in some hidden place. It happened in the middle of a school event, in front of other students, with adults nearby and a community watching.
Austin was rushed for medical help after the stabbing, but he later died from his injuries. Coaches and others tried to save him. His twin brother, Hunter, was nearby during the chaos, a detail that made the courtroom testimony even more painful for the family.
The Jury Chose Murder, Not Self-Defense
They did not.
The jury found Anthony guilty of murder and sentenced him to 35 years in prison. Jurors took about two and a half hours to decide the sentence after hearing arguments in the punishment phase. Anthony faced a range that could have stretched from five years to life in prison.
During sentencing, Anthony’s mother testified about her son and asked jurors to see his remorse. CBS Texas reported that she described him as her firstborn and said he was sorry for what he did. It was a mother’s plea in a courtroom already filled with grief.
Prosecutors pushed jurors to focus on Austin’s lost future. They reminded the courtroom that Austin would never graduate, build a life, meet future milestones, or continue the dreams his family believed were ahead of him. That argument appeared to land with jurors who were asked to weigh not only Anthony’s age, but the permanent loss suffered by the Metcalf family.
The verdict did not erase the pain. No sentence could. But for Austin’s family, the decision marked a public acknowledgment that what happened at that track meet was a crime worthy of decades behind bars.
For Anthony’s family and supporters, the sentence brought another kind of grief. A teenager at the time of the stabbing will now spend much of his adult life in prison. The courtroom outcome left one family mourning a son who will never come home and another facing the reality that their son’s future has been reshaped by a single violent act.
Frisco Is Still Living With the Aftershock
The courtroom may have delivered a sentence, but Frisco is still left with the emotional wreckage. Students who witnessed the stabbing had to testify about a moment no teenager should have to carry. Coaches and school staff were forced to relive the panic of trying to save a student in front of his peers.
Families who sent children to a track meet now have to live with a fear that feels far less distant than it did before. Frisco ISD responded to the verdict by saying it respected the judicial process and would continue supporting students with compassion and care. That kind of statement matters, but it also shows the depth of the wound.
The district is not simply moving past a legal case. It is trying to steady a school community that watched one of its own die in a place meant for competition, teamwork, and achievement.
The case also drew national attention because of the racial and social tensions surrounding it. Anthony is Black, and Austin was white. Online arguments quickly spread after the stabbing, and the case became part of a much larger and often bitter public debate. Some people focused on school safety. Others focused on self-defense law. Others questioned race, public pressure, and fairness in the courtroom.
CBS Texas reported that Anthony’s legal team filed a notice of appeal less than 24 hours after the conviction and sentence. That means the legal process may continue, even as the first major courtroom chapter has closed.
For the Metcalf family, however, the central truth remains painfully simple. Austin went to a track meet and never came home. His name is now attached to a case that will be studied and debated, but to his loved ones, he was not a headline. He was a son, a brother, a student, an athlete, and a young man with a future.
For parents across Texas, the case comes across as a warning. Teen conflict can turn deadly when anger, fear, pride, and a weapon collide. Schools can tighten rules, adults can increase supervision, and communities can demand answers, but the deeper challenge is teaching young people how to step away before a moment becomes irreversible.
The 35-year sentence gives the case a legal ending for now. It does not give the community an emotional one. Frisco is left with a harder question, the kind no courtroom can fully answer: how does a school community rebuild trust after a place built for young dreams becomes the scene of a young life lost?
