Collin County released surveillance video, crime scene photos and 911 audio Friday from Karmelo Anthony’s first-degree murder trial — giving the public its first look at evidence shown to jurors after Anthony was sentenced to 35 years in prison for fatally stabbing 17-year-old Austin Metcalf at a Frisco, Texas, high school track meet on April 2, 2025.
One surveillance clip shows Anthony fleeing the tent where the stabbing occurred, running through the stands and onto the track at David Kuykendall Stadium. A second shows him walking past the track tents before the attack. A third captures officers taking him into custody on the track shortly after.
The arrest
Body camera footage released as part of the trial exhibits shows an officer checking Anthony’s pockets, then asking his name, school and grade before placing him in a police vehicle. In the footage, Anthony tells officers: “He put his hands on me. I told him not to. He put his hands on me.” As officers arrive, a voice off camera is heard saying, “I know how it goes. I’m not alleged. I did it.”
Among the physical evidence made public Friday: the folding Ozark Trail multi-tool knife prosecutors said Anthony pulled from his backpack during the confrontation, a blood-soaked jacket, and a photo of a deep gash on Metcalf’s chest with a forensic ruler placed beside the wound. Prosecutor Bill Wirskye described the 3½-inch blade as “not particularly a quality knife” during trial.
The 911 audio captures a caller reporting that an athlete had been stabbed and that an Army veteran was compressing the wound. “There’s a lot of blood. He’s not breathing,” the caller said. Voices in the background can be heard shouting, “Stay with me, Austin!” and “Fight through, Austin!” as bystanders performed chest compressions. The call ends when paramedics arrive.
Prosecutors said Anthony stabbed Metcalf after Metcalf and his brother confronted Anthony while he sat in his team’s tent at Memorial High School. Anthony, who was 17 at the time, admitted the stabbing but argued self-defense. The jury rejected that claim earlier this month.
Collin County District Judge John Roach authorized the release. “Now that the trial is over, it’s important to me to provide transparency,” Roach told Fox News Digital.
Metcalf’s father, Jeff Metcalf, said the footage contradicts claims that circulated online that Anthony was jumped by multiple students. “There was no four-on-one,” he said. “Look at the video. There’s a shove and there’s a stab, and it’s over and he runs away. That’s it.”
Anthony will be eligible for parole after serving half his 35-year sentence. His appeal is pending; a new attorney recently joined his legal team after Anthony claimed he can’t pay for counsel.
