A chilling crime has rocked the sports world, leaving a Texas community in mourning and disbelief. On April 2, 2025, 17-year-old high school football standout Austin Metcalf was fatally stabbed at Kuykendall Stadium in Frisco during a track and field meet, dying in the arms of his twin brother, Hunter. The alleged perpetrator, 17-year-old Karmelo Anthony, confessed to the brutal killing as police apprehended him, delivering six haunting words that have sent shivers down the spines of investigators and the public alike: “Not alleged, I did it.” This cold admission, captured in a probable cause affidavit, has thrust the case into the national spotlight, exposing a tragedy as perplexing as it is horrifying.

The incident unfolded in broad daylight, shattering the routine of a typical school event. According to police reports, Anthony pulled a knife from his backpack and stabbed Metcalf, a beloved athlete known for his speed and charisma, in a sudden and unprovoked attack. Witnesses described a scene of chaos as Metcalf collapsed, with Hunter rushing to his side, cradling him as he took his final breaths. “I tried to help him,” a devastated Hunter later told WFAA, his voice breaking. Their parents arrived moments later, finding their son lifeless, a sight father Jeff Metcalf called “murder, plain and simple.” The stadium was locked down, and students were sent home as authorities swarmed the scene.

Anthony’s arrest came swiftly, but it was his words that turned a tragic story into something even more unsettling. As officers ordered him to raise his hands, he initially shouted, “I was protecting myself,” hinting at a self-defense claim. Yet, when an officer referred to him as a suspect, Anthony’s chilling response cut through the tension: “Not alleged, I did it.” The stark confession, paired with a question about whether Metcalf would survive, has left investigators grappling with his motives. Charged with murder, Anthony faces 5 to 99 years in prison if convicted, but the why behind the attack remains elusive.

Metcalf’s death has devastated Frisco, where he was a rising star with dreams of college football. Tributes on X poured in, with one user writing, “Austin was a light—taken too soon.” His twin, Hunter, now faces an unimaginable void, while their parents wrestle with grief and unanswered questions. Meanwhile, Anthony’s actions have sparked outrage and debate. Some on X speculate about a personal grudge, others about a deeper instability, but police have yet to release a motive, leaving the community to piece together rumors and fragments.

This isn’t just a local tragedy—it’s a stark reminder of youth violence’s toll. As the case heads to court, the six words Anthony uttered linger like a dark echo, a confession that offers no comfort, only dread. For now, Frisco mourns a fallen hero, while the world watches a story of promise cut short by a blade—and a teenager’s terrifying resolve.
