The murder trial of Karmelo Anthony has attracted national attention, raising concerns about self-defense, race and liability.
The Texan teenager was sentenced to 35 years in prison on Tuesday, June 9, for fatally stabbing another track and field athlete during a competition at a high school in the Dallas suburbs.
When did Karmelo Anthony stab Austin Metcalf?
The incident took place on April 2, 2025, when Anthony, then 17, was attending a high school track meet at Kuykendall Stadium in Frisco, Texas.
As the rain began to fall, Anthony took shelter under the awning assigned to Memorial High School, where Austin Metcalf was also a student.
Testimony indicates that Metcalf and his gang urged Anthony to leave the area. According to police testimony, Anthony reached into his bag and said, “Come touch me and see what happens.” » Upon touching him, Anthony pulled out a knife and stabbed Metcalf in the heart. The two young men did not know each other.
Why did Karmelo Anthony stab a fellow athlete?
The two sides present very different explanations for why Anthony stabbed Austin Metcalf. Prosecutors argued that Anthony was the aggressor. They said he provoked Metcalf and then used deadly force in response to a simple push. This indicates a disproportionate reaction that amounts to murder. Throughout the trial, prosecutors argued that Anthony intentionally killed Metcalf without any legal justification.
The defense, however, argued that Anthony’s reaction was self-defense. Anthony’s lawyer pointed to Texas law that does not require waiting to be struck. The defense argued that Anthony felt threatened and reacted to protect himself.

Key evidence
Prosecutors backed their argument with testimony from the medical examiner, who described a larger, gaping wound to Metcalf’s chest, with the knife piercing his heart.
Final verdict
The jury rejected the self-defense claims and the request for a lesser charge of manslaughter. Metcalf’s father, Jeff, told Anthony after the sentencing: “You have failed yourself, you have failed your parents, and you have failed society.” »
