The tragic stabbing death of 17-year-old Austin Metcalf at a Texas high school track meet in April 2025 sparked a closely watched murder trial that gripped the nation. At the center of the case was fellow student-athlete Karmelo Anthony, who was accused of plunging a folding knife into Metcalf’s chest during a dispute over seating. The incident, which unfolded in front of dozens of teenagers, quickly became a flashpoint for debates over self-defense, race, and school safety.
On April 2, 2025, a rainy morning at Kuykendall Stadium in Frisco, Texas, Karmelo Anthony, then a 17-year-old student at Centennial High School, found himself under a team tent belonging to Frisco Memorial High School. The tent was occupied by members of the Memorial track team, including Austin Metcalf and his twin brother, Hunter. According to witness testimony, Metcalf and others asked Anthony to leave the area multiple times — as many as fifteen times — according to some accounts.
When Anthony refused to vacate, the situation escalated. Witnesses recounted that Anthony, keeping his hands hidden in his backpack, eventually challenged Metcalf, saying, “Touch me and see what happens.” The confrontation turned physical when Metcalf shoved Anthony, who responded by pulling out a knife and stabbing him once in the chest. Metcalf’s final words, “I have been stabbed,” were spoken as he limped into the arms of his twin brother, where he bled to death.

The Fatal Encounter
The prosecution’s case relied heavily on eyewitness testimony from students who were present under the tent. Multiple witnesses described the confrontation in detail, challenging Anthony’s assertion that he was acting in self-defense. One student witness told jurors that the shove from Metcalf was “somewhere in between a light shove and a hard shove” and that he did not believe the stabbing was justified, characterizing it as “lethal force against non-lethal.”

Another witness testified that no one had ganged up on Anthony and that a fight was not anticipated, with only “minor pushing at most” expected. Instead, after being shoved, Anthony pulled a 3.5-inch folding knife from his bag, stabbed Metcalf in the chest, and then threw the knife into the bleachers before fleeing. The prosecution argued that this was a “senseless murder” carried out by an aggressor, not a victim acting in self-defense.

The Battle of Self-Defense
Karmelo Anthony’s defense team, however, painted a starkly different picture of the events. They argued that Anthony was the one who was outnumbered and feared for his safety, leading him to act in what he believed was self-defense. Anthony had told police immediately after his arrest that he was “protecting himself” during the altercation. His attorneys highlighted that Anthony did not have a prior criminal record, excelled academically with a 4.0 GPA, and was a nominee for team captain.
The defense also noted the physical disparity between the two teenagers, arguing that Metcalf and his twin brother were much larger than their client. However, witness testimony that Anthony was the one who antagonized Metcalf and was asked to leave numerous times before the shove ultimately undermined the self-defense claim. In the end, the jury did not find the argument convincing.
