Karmelo Anthony, a 17-year-old student at Centennial High School in Frisco, Texas, is facing a first-degree murder charge in the stabbing death of fellow student Austin Metcalf, 17, during a track meet in April 2025. The trial is scheduled to commence on June 1, according to court records. If convicted, Anthony could face a sentence ranging from 5 years to life in prison, as Texas law treats 17-year-olds as adults. The incident occurred during a rain delay at Memorial High School, where a confrontation between Anthony and Metcalf escalated after Metcalf reportedly asked Anthony to leave the event. Witnesses allege that Anthony warned Metcalf before pulling out a knife and stabbing him once in the chest. Metcalf died shortly after the incident, with his twin brother present. Following the stabbing, a campaign supporting Anthony was initiated, and his family has raised concerns about safety and discrimination as the trial approaches.
