On June 9, 2026, a Collin County jury sentenced 19-year-old Karmelo Anthony to 35 years in prison for the murder of 17-year-old Austin Metcalf, bringing to a close a trial that gripped the North Texas community and reverberated far beyond. The fatal stabbing occurred at a high school track meet in Frisco, Texas, on April 2, 2025, and has since become a flashpoint for conversations about youth violence, self-defense, and community accountability.
The events unfolded at Kuykendall Stadium during a rainy track and field competition involving multiple schools in the Frisco Independent School District. Anthony, then 17 and a student at Frisco Centennial High School, was sitting under the Memorial High School team tent—Metcalf’s school—seeking shelter from the rain. According to testimony reported by FOX 4 and ABC News, an argument broke out when Metcalf and his teammates repeatedly asked Anthony to leave the tent. Witnesses described the confrontation as escalating over four to six minutes, with some students recalling Anthony warning, “Touch me and see what happens,” while others heard Metcalf say, “I’m not going to fight you.”
The altercation turned deadly when Metcalf, an 11th grader at Frisco Memorial, pushed Anthony, who remained seated with his bag on his lap. Several witnesses described the push as either a two-handed “lineman move” or a smaller one-handed shove. In the chaos that followed, Anthony drew a pocket knife and stabbed Metcalf in the chest, perforating his right ventricle, according to Collin County Chief Medical Examiner Dr. Elizabeth Ventura’s testimony. The knife, a 3.5-inch folding blade, was later found on the bleachers. Efforts to save Metcalf included CPR from the school’s athletic trainer and a football coach, but he was ultimately pronounced dead at a nearby hospital.
Anthony did not testify during the trial, but body camera footage and arrest reports captured his immediate reaction. “He put his hands on me. I stabbed him,” Anthony told a coach and later repeated to responding officers, as reported by FOX 4. He also asked officers if what happened could be considered self-defense. Throughout the trial, Anthony’s defense attorney, Mike Howard, maintained that the teen acted in fear and chaos, feeling threatened by Metcalf, who was significantly larger, and surrounded by a group of students. “You are justified to use deadly force when you believe it is immediately necessary,” Howard argued, emphasizing the physical disparity between the two boys and the crowded, tense environment under the tent.
The prosecution, led by Collin County First Assistant District Attorney Bill Wirskye, painted a starkly different picture. Prosecutors called the stabbing “senseless” and “plain and simple murder,” arguing that Anthony provoked the confrontation and responded with disproportionate force. “You don’t get to meet a shove with a stab—especially if you provoke a shove,” Wirskye told jurors, according to WFAA. He highlighted that Anthony brought a knife to a school event where weapons were prohibited, kept it hidden, and used it without warning. “He used lethal force against nonlethal force,” Wirskye said. “That equals murder, plain and simple. Unjustified murder.”
The jury deliberated for about three hours before finding Anthony guilty of first-degree murder. They then spent an additional two hours and 20 minutes considering his sentence. Although Texas law allowed the jury to consider a lesser charge of manslaughter or a reduced sentence for “sudden passion”—which could have limited Anthony’s punishment to 20 years—they ultimately sentenced him to 35 years. He will be eligible for parole after serving half of his sentence.
The trial was marked by intense public scrutiny, with a gag order and electronics ban in the courtroom to minimize outside influence. Crowds gathered outside the Collin County courthouse in McKinney, some holding signs supporting either side. Demonstrators and activists, including the Next Generation Action Network, urged calm and “revolutionary peace” as the case drew national attention and sparked heated debate on social media. The selection of the jury itself became a point of controversy, as no Black jurors were seated, prompting a denied defense challenge on racial grounds.
After the verdict, the Metcalf family delivered emotional victim impact statements, finally free from the constraints of the gag order. Meghan Metcalf, Austin’s mother, addressed Anthony directly: “You may have been given a sentence of 35 years. You should feel lucky. I’ve been sentenced to a lifetime without my son.” Jeff Metcalf, Austin’s father, spoke with visible anger and heartbreak, describing the public backlash and the pain of being unable to defend his son’s memory during the trial. “I said from Day 1 this was never about race. It’s about right and wrong. We are all humans. We all bleed the same color. You will face those consequences starting today,” he declared, also revealing that the family had been targeted by multiple dangerous “swatting” calls.
Hunter Metcalf, Austin’s twin brother, asked Anthony to look him in the eye, expressing the ongoing struggle to forgive and understand the loss: “You took everything from me. I wake up every morning and his door is still shut.” The family also announced a scholarship in Austin’s memory, seeking to create some good from the tragedy.
Anthony’s mother, Kayla Hays, was the only defense witness during the punishment phase, pleading with jurors to show mercy for her son, whom she described as deeply sorry for his actions. Anthony, who cried during the proceedings, ultimately waived his right to testify in his own defense.
Collin County District Attorney Greg Willis, in remarks following the sentencing, emphasized that the process had delivered accountability: “Today, justice was served. A year ago, when this senseless murder unfolded, I said that it had struck a deep nerve in Collin County and far beyond. I asked our community to ignore all the noise and instead be level-headed and patient as the process worked. And today, the process delivered accountability.” Willis also thanked the “brave kids” who testified despite the trauma of witnessing the fatal altercation.
The Frisco Independent School District released a statement respecting the judicial process and pledging continued support for its students, acknowledging the deep grief and strong emotions stirred by the trial. “We know this trial has brought strong emotions and deep grief, and we ask that our community continue to support each other with respect, sensitivity and understanding,” the district said.
Outside the courthouse, emotions continued to run high. At one point, a man was arrested for reportedly assaulting another in the crowd, a reminder of the tensions that have surrounded the case from the start.
As the community moves forward, the case remains a sobering reminder of how quickly lives can be changed forever by a moment of violence—and how the pursuit of justice, though imperfect, can bring a measure of accountability and closure to those left behind.
