A Collin County jury found 19-year-old Karmelo Anthony guilty of murder on June 9, 2026, in the death of Austin Metcalf [1], [2].

The conviction concludes a high-profile trial involving a violent incident at a youth sporting event, raising concerns about safety and violence within school-sanctioned activities.

The case centered on a stabbing that occurred during a Frisco high school track meet in 2025 [3]. The victim, Austin Metcalf, was 17 years old at the time of the attack [1]. The proceedings took place at the Collin County Courthouse in Frisco, Texas [2], [5].

Throughout the trial, prosecutors presented evidence to show that Anthony was responsible for the stabbing. While some reports on the day of the verdict indicated the jury was still deliberating or that closing arguments were beginning [6], [7], subsequent reports confirmed the jury reached a guilty verdict [1], [2], [4].

Under Texas law, a conviction for murder carries significant legal consequences. Reports said that a person convicted of murder in this context could face a sentence of 35 years [3].

The incident sparked widespread attention due to the age of the participants and the setting of the crime. A track meet is typically a safe environment for student-athletes, making the nature of the attack particularly shocking to the community [5].

The conviction of Karmelo Anthony underscores the legal system's approach to violent crimes committed by young adults. By securing a murder conviction rather than a lesser charge, the state establishes a strict precedent for violence occurring at educational and athletic events, while the potential 35-year sentence reflects the severity of the crime's impact on the victim and the community.
