Analysis
Verdict and charges
A Collin County jury found Karmelo Anthony guilty of murder in the stabbing death of 17-year-old Austin Metcalf at Kuykendall Stadium in Frisco on April 2, 2025. The jury heard testimony over several days from dozens of witnesses and returned its decision after a trial that began with jury selection on June 1.
What prosecutors argued
Prosecutors said Anthony intentionally stabbed Metcalf during an altercation near a team tent area at the track meet. They presented 21 witnesses and focused heavily on witness accounts and medical evidence. Collin County Chief Medical Examiner Dr. Elizabeth Ventura testified that the stab wound pierced Metcalf’s heart and was not survivable. Student witnesses described the moments before and after the stabbing, and one said he did not see the act as self-defense.
How the defense responded
Defense lawyers argued Anthony was protecting himself and challenged the prosecution’s version of the confrontation. They called witnesses who said athletes often moved through other schools’ tents at track meets. One coach testified that Anthony’s teammates had considered him for a captain role, while also acknowledging there was no reason to have a knife at a track meet. Other defense witnesses described the scene as chaotic, and one student said he may have seen someone being pushed or punched, though his recollection did not fully match video evidence shown at trial.
What happens next
Judge John Roach allowed jurors to consider manslaughter as a lesser charge, but the murder conviction means Anthony now faces sentencing. Under Texas law, the punishment range for murder is five to 99 years or life in prison. The case also drew heightened security and public controversy throughout North Texas.
