A Collin County jury deliberated roughly three hours Tuesday before finding 19-year-old Karmelo Anthony guilty of first-degree murder in the stabbing death of Austin Metcalf, a 17-year-old high school athlete killed at a track and field event in Frisco, Texas, on April 2, 2025. Anthony, who was 17 at the time of the attack, now faces up to life behind bars. The jury will determine his sentence.
Anthony sobbed as the verdict was read. He had entered the courtroom looking glum, eyes down, and did not immediately speak with his lawyers, the New York Post reported. When the foreman announced the conviction on the top charge, not the lesser option of manslaughter, Anthony broke down.
Outside the courthouse, about 200 protesters for and against Anthony clashed. Some of Anthony's supporters turned the verdict into a grievance about race, shouting accusations of racism at the justice system and the jury itself.
The conviction followed four days of testimony from students, coaches, medics, officials, and law-enforcement officers who were at Kuykendall Stadium or responded to the scene. The picture they painted was stark.
Teammates told jurors the confrontation started when Metcalf, a student at Frisco Memorial High School, asked Anthony, from rival Frisco Centennial High School, to move out from under the Memorial team's tent in the bleacher area. Anthony refused. Witnesses said he was asked roughly 15 times to leave.
Instead of walking away, Anthony warned Metcalf: "Touch me and find out." Witnesses said his hand was already in his backpack, ready to grab something. When Metcalf eventually shoved him, Anthony pulled a semi-serrated folding knife from his bag and stabbed Metcalf once in the chest.
Autopsy photos shown at trial revealed a 2-inch wound. It was enough. Metcalf died.
After the stabbing, jurors heard, Anthony ditched his knife and headed for the exit. Coaches stopped him before he could leave. Anthony told the coaches he had warned Metcalf not to touch him, admitted to the stabbing, and contended it was self-defense. That self-defense argument became the centerpiece of his legal strategy at trial. He did not take the witness stand.
A fellow classmate testified that Anthony appeared "distraught" in the moments after the attack, crying and hugging a coach. One coach broke down on the witness stand recalling Metcalf's death. Hunter Metcalf, Austin's twin, sat next to his parents in court for the verdict. Jurors also heard that Hunter and others had rushed to try to save Austin after the stabbing.
The Metcalf family stepped out of the courtroom when graphic evidence was presented. They returned to hear the verdict that held their son's killer accountable.
From the start, some of Anthony's supporters tried to reframe the case. They cast Metcalf as an aggressor and suggested the prosecution was racially motivated. The jury, which included white, Asian, and Hispanic members, did not include a single Black juror, a fact that became a rallying point outside the courthouse.
One protester screamed, "This whole thing's been racist. We didn't make it racist!" Another yelled a profanity-laced accusation: "Y'all used to locking up n, s any g*****n way!" A demonstrator demanded, "Tell those white folks, why is a black boy in front of an all white jury? When has a white boy been in front of an all black jury? Never!"
The anger was loud. But it did not change the facts the jury weighed. Anthony was asked more than a dozen times to leave someone else's space. He refused. He threatened. He armed himself. He stabbed a 17-year-old once in the chest. And then he tried to leave.
Jurors had the option of convicting on manslaughter, a lesser charge that would have reflected a finding of recklessness rather than intent. They chose the top charge. Three hours of deliberation, four days of testimony, one conclusion: first-degree murder.
Anthony's legal defense raised more than $690,000, a figure that reflects the intense public attention the case drew. Some sympathizers portrayed Metcalf as a "white bully" and cast the stabbing as a justified response to physical aggression. The defense leaned on the shove Metcalf delivered before the stabbing.
But a shove does not justify a knife. Texas law permits the use of force in self-defense, but the force must be proportional to the threat. A jury of Anthony's peers, the only people who sat through every minute of testimony, concluded that pulling a blade and plunging it into a teenager's chest was not a proportional response to being pushed. The verdict was decisive.
The case is one of several recent incidents that have forced communities to grapple with lethal violence among young people. In another case drawing national attention, a 12-year-old in Los Angeles was arrested on murder suspicion after a classmate died from a metal bottle strike at school.
Before the verdict, NBC DFW reported that Anthony's mother took the witness stand, wept, and begged for mercy for her son. The plea came too late to affect the conviction. Sentencing remains ahead, and the same jury will decide how long Anthony spends behind bars.
The Metcalf family has said little publicly. They have let the legal process speak. Hunter Metcalf, who lost his twin brother at a high school sporting event, sat in the courtroom and watched the system deliver its answer.
Frisco is a fast-growing suburb north of Dallas, the kind of place families move to for good schools and safe neighborhoods. That a dispute over bleacher seating at a track meet ended with a teenager dead and another convicted of murder is a grim marker of how quickly ordinary friction can turn fatal when someone brings a weapon and a willingness to use it.
Across Texas, criminal cases involving young defendants continue to test the justice system's capacity to hold individuals accountable while communities fracture along political and racial lines. In San Antonio, a North East ISD principal recently resigned after a family violence arrest, another reminder that consequences still follow conduct, at least when the system works.
Anthony's defense team asked the jury to see a teenager who felt threatened and reacted. The jury saw something different: a teenager who was told repeatedly to leave, who refused, who issued a threat, who reached into a bag for a folding knife, and who used it. The sequence matters. The jury weighed it.
Self-defense is a serious legal claim. It exists to protect people who face genuine, imminent danger and have no reasonable alternative. It does not exist to shield someone who engineers a confrontation, refuses every off-ramp, and then escalates to deadly force. The Collin County jury understood the distinction.
Violent crime among teenagers demands clear consequences, not excuses dressed up in political grievance. In a recent Iowa case, a father's deadly rampage left six family members dead, another horrific reminder that when violence is met with anything less than full accountability, the message to the next offender is dangerously unclear.
The protesters outside the Collin County courthouse wanted the story to be about race. The jury heard four days of evidence and decided the story was about a knife, a refusal to walk away, and a 17-year-old who bled out at a track meet.
Austin Metcalf's family now waits for sentencing. They have already lost what no verdict can return. The least the system owes them, and every family in every bleacher in every stadium in Texas, is the plain acknowledgment that what happened to their son was not self-defense. It was murder.
When a community cannot say that plainly, without hedging and without apology, something far more important than a court case has already been lost.
