A Collin County jury took less than three hours Tuesday to convict Karmelo Anthony of murder, rejecting his self-defense claim in the 2025 stabbing death of 17-year-old Austin Metcalf at a North Texas track meet.
The verdict came swiftly and without ambiguity. Jurors in McKinney, Texas, found Anthony, now 19, guilty of murder on Tuesday, choosing the top count over a lesser manslaughter option the judge had made available. Deliberations lasted fewer than three hours. Anthony, who was 17 at the time of the stabbing and was tried as an adult, faces between five years and life in prison. Sentencing testimony began the same afternoon.
The stabbing took place April 2, 2025, at Kuykendall Stadium in Frisco during a Frisco Independent School District track and field competition. Witnesses testified that Anthony, competing for a rival school, refused to leave a tent belonging to Metcalf's team. The two had never met before that day. An argument followed, and Anthony pulled a knife and stabbed the unarmed Metcalf in the chest, according to witness testimony at trial. Metcalf, a 17-year-old competing for a neighboring school, died from the wound.
Anthony did not testify on his own behalf. His attorneys argued he feared for his safety and acted in self-defense, a claim the jury flatly rejected. Multiple student witnesses described a heated but one-sided confrontation at the tent, and prosecutors told jurors the stabbing was an act of lethal aggression over a tent dispute, against a boy who never drew a weapon.
The case drew intense national attention well before the trial began. In the months following the arrest, social-media campaigns identified and circulated personal information about people connected to the case, a practice critics called doxxing. Demonstrators gathered outside the courthouse during the trial's week-long run, and online debates about race and self-defense ran far ahead of what any witness had actually testified to. The trial itself proceeded without disruption, and the jury heard the case on the evidence alone.
When the verdict was read, a crowd outside the courthouse chanted "Free Karmelo," and some supporters told CBS News Texas they believed the justice system had failed Anthony. Central to that argument is the absence of any Black jurors on the panel. Prosecutors used their peremptory strikes to remove qualified Black prospective jurors during jury selection, drawing a formal objection from defense attorneys. Judge John Roach overruled the challenge, finding the removals were based on race-neutral grounds, specifically the jurors' occupations as educators, according to court reporting by CBS Texas and NewsNation.
The jury composition is widely expected to anchor an appeal. Defense attorneys can argue that the prosecution's strikes against Black jurors violated constitutional equal-protection guarantees under Batson v. Kentucky, the 1986 Supreme Court precedent that bars race-based jury exclusion. Whether the trial court's ruling survives that scrutiny will likely determine whether Anthony ever gets a new trial.
The Record at Trial
The racial framing that dominated social media for months ran into a straightforward evidentiary record in the courtroom. Most witnesses who testified were students, many of them peers of both Anthony and Metcalf. Their accounts described a confrontation that escalated on Anthony's side, against a victim who carried no weapon. At the start of the trial, Confederate flag-waving counterprotesters appeared outside the courthouse, according to the Dallas Observer, adding charged symbolism to what the jury was tasked with deciding on the facts alone.
The same jury that convicted Anthony will determine his sentence. His mother, Kala Hayes, took the stand during the punishment phase as the defense's only witness, breaking down as she told jurors her son "is very sorry for what he did" and pleading for mercy, according to WFAA. If jurors find Anthony acted under the immediate influence of "sudden passion," the maximum sentence drops to 20 years; otherwise the full range of five years to life applies. A sentence is expected within days, and with appeals already anticipated on the jury composition question, the legal fight over Karmelo Anthony's fate is far from finished.
