A murder trial has opened in Collin County, Texas, for Karmelo Anthony, 19, who is accused of fatally stabbing 17-year-old Austin Metcalf during a high school track meet in Frisco on 2 April 2025. The case has attracted national attention partly due to its racial dimension — Anthony is Black and Metcalf was white — though prosecutors told the all-white jury that race plays no role in the case. The defence argues Anthony acted in self-defence after Metcalf initiated a physical confrontation, while prosecutors say he buried a knife into Metcalf's chest and fled; Anthony reportedly told a school officer at the scene, "I'm not alleged, I did it." If convicted of first-degree murder, Anthony faces between five years and life in state prison.
