MCKINNEY, Texas — A dramatic day in the Karmelo Anthony murder trial left jurors visibly shaken as prosecutors presented a bloodied knife and the defendant’s own alleged words to police: “I’m not alleged. I did it.”
The 19-year-old Anthony stands charged with first-degree murder in the fatal stabbing of 17-year-old Austin Metcalf during a confrontation at a Frisco Independent School District track meet on April 2, 2025. What began as a dispute over seating under a team tent ended with Metcalf dead from a single stab wound to the chest.
On Wednesday, the courtroom fell silent as prosecutors introduced graphic evidence, including the bloodied knife recovered at the scene. Witnesses testified that Anthony was the aggressor, provoking the fight before allegedly stabbing Metcalf in a “lightning-fast” motion. Haunting bodycam footage from the immediate aftermath further intensified the emotional weight of the proceedings.
Anthony’s defense team is vigorously arguing self-defense, claiming their client acted after Metcalf allegedly put his hands on him. However, the combination of physical evidence and Anthony’s own reported statement to officers has created a challenging moment for the defense.
The trial, which has drawn intense local and national attention, centers on a split-sec
ond decision at a school athletic event that ended one young life and forever altered another. Anthony faces five to 99 years in prison if convicted.
Prosecutors have painted a picture of an unprovoked attack, while the defense maintains Anthony feared for his safety and acted in the heat of the moment. The jury is expected to begin deliberating soon, with a verdict possible by next week.
The case has already sparked heated discussions about youth violence, self-defense laws in Texas, and the role of school safety at athletic events. Both families have maintained a low profile inside the courtroom, though supporters on both sides have gathered outside the Collin County Courthouse.
As the trial moves toward its conclusion, the focus remains on whether the jury will accept the self-defense claim or hold Anthony accountable for the fatal stabbing that occurred in front of numerous student-athletes and spectators.
