A Collin County court has released a series of graphic materials related to the murder trial of Karmelo Anthony, who was convicted for the stabbing death of 17-year-old Austin Metcalf during a track meet in Frisco. The evidence was made public on Friday, 10 days after Anthony was sentenced to 35 years in prison.

The 296th District Court's release includes 911 emergency call recordings from the day of the incident, crime scene and autopsy photographs, exhibits of bloody clothing, images of the alleged weapon, and surveillance footage captured at Kuykendall Stadium. The files also contain numerous family photographs of Anthony that were presented during the two-week trial. Among the visual evidence is a grainy, wide-angle video taken from an east stadium camera, which depicts the confrontation and its immediate aftermath from a distance.

Anthony, formerly a student at Frisco Centennial High School, was found guilty of murder for the fatal stabbing of Metcalf, a Frisco Memorial High School athlete. The incident occurred on April 2, 2025, beneath a team tent set up at the event to provide shelter from severe weather. According to prosecutors, the fatal altercation broke out under this tent, where Metcalf was stabbed once in the chest and died at the scene.

During the trial, Anthony's defense team contended that he acted in self-defense. The case attracted significant national media coverage and sparked widespread online debate. Discussions surrounding the trial included issues of race, public protests, online threats, and claims of doxing involving individuals connected to the case.

Anthony has filed a notice of appeal following the verdict. The recent public release of evidence provides insight into the materials that jurors reviewed when deliberating the case.
