A tragic stabbing at a Texas high school track meet on April 2, 2025, claimed the life of 17-year-old Austin Metcalf. The incident occurred during a district championship at Frisco High School’s Kuykendall Stadium.

The suspect, 17-year-old Karmelo Anthony from Centennial High School, was arrested and charged with murder. Police say Karmelo admitted to the stabbing, claiming self-defense after a verbal argument escalated.

Collin County District Attorney Greg Willis noted that, under the 2005 Supreme Court ruling Roper v. Simmons, Karmelo cannot face the death penalty or life without parole because he was a minor at the time. If convicted, he faces 5 to 99 years in prison.
