Karmelo Anthony, 19, has been found guilty of murder in the fatal stabbing of 17-year-old Austin Metcalf during a high school track meet in Frisco, Texas.
The verdict brings the case into its next phase, where sentencing will determine how long he may spend in prison.
Anthony was indicted on first-degree murder charges over the April 2, 2025 stabbing at a Frisco Independent School District stadium during a track and field championship.
Prosecutors described the killing as “senseless” and “plain and simple murder,” while the defense argued Anthony acted in self-defense after an altercation under a school tent in the stadium bleachers.
Jurors heard several days of testimony before reaching a verdict within hours of deliberation.
Under Texas law, first-degree murder carries a potential sentence of 5 to 99 years or life in prison, depending on how the charge is ultimately applied and what the jury decides.
A sentencing date has not been publicly announced, and the case remains under a gag order, with further proceedings expected to clarify sentencing timelines in the coming weeks.
