Medical Examiner Says 17-Year-Old Austin Metcalf Was Stabbed Through Heart as Prosecution Rests

Summary
Collin County’s chief medical examiner testified Saturday that Austin Metcalf, 17, died from a 2-inch chest wound that pierced the heart, calling the injury unsurvivable homicide.
That testimony closed the prosecution’s case in Karmelo Anthony’s murder trial over the April 2, 2025 stabbing at a Frisco track meet, where Anthony, now 19, has pleaded not guilty and claims self-defense.
Student witnesses for both sides described a dispute after Anthony allegedly refused to leave a Memorial High School tent; one prosecution witness said Anthony was the aggressor, while a defense witness said Austin Metcalf tapped him before the stabbing.
Judge John Roach allowed autopsy photos over defense objections, prompting Metcalf’s mother to leave the courtroom as friends remained in tears. The trial resumes Monday.
The case has drawn national attention amid racial tensions—Anthony is Black and Metcalf was white—and Anthony could face 5 years to life in prison if convicted.
