Karmelo Anthony runs away after murdering Austin Metcalf: surveillance video

New videos and photos released Friday show the moments leading up to and after Karmelo Anthony stabbed Austin Metcalf to death with a knife during a confrontation at a Texas high school track meet.

The videos were made public Friday by Collin County court following Anthony's first-degree murder conviction earlier this month. 

One piece of surveillance showed Anthony fleeing the tent where he stabbed Metcalf, running through the stands and onto the track in Frisco, Texas, on April 2, 2025.

Among the other images released were a blood-soaked jacket and the folding Ozark Trail multi-tool knife prosecutors said was used to fatally stab Metcalf, as well as the bleachers at David Kuykendall Stadium in Frisco on April 2, 2025.

The newly released trial exhibits from the murder case include crime scene photos, images of the knife prosecutors said was used in the stabbing, 911 calls and police body-camera footage shown to jurors.

The body-camera video captures the moments after Anthony was taken into custody following the fatal stabbing of Metcalf at a high school track meet. In the footage, Anthony is heard telling officers, "He put his hands on me. I told him not to. He put his hands on me."

Anthony used a blade to stab Metcalf after the teen and his brother confronted him while sitting in their team’s tent at Memorial High School, prosecutors said. Anthony, who was 17 at the time, admitted he stabbed Metcalf but claimed he acted in self-defense.

During Anthony's trial, prosecutor Bill Wirskye noted that the 3½-inch-long weapon used by Anthony was "not particularly a quality knife," but it ultimately proved lethal when he pulled it from his backpack during the confrontation.

Anthony was sentenced this month to 35 years in prison for the stabbing, which ignited a wave of criticism from his supporters over the makeup of the jury. Anthony will be eligible for parole after serving half his sentence.

Other images released Friday show a deep gash on Metcalf's chest with a forensic ruler placed beside the wound. Another shows Anthony near the football field where the track meet was being held at the time of the killing. 

A short video appears to show Anthony being arrested by responding officers. One of the officers says to another as they arrive: "This is the alleged suspect."

"I know how it goes," a voice is heard off camera. "I'm not alleged. I did it."

Collin County District Judge John Roach, who authorized the release of the images and videos, told Fox News Digital that he understood the public's desire to know what happened in the case. 

"The overwhelming focus on my ruling regarding the media in the courtroom was to protect the process, witnesses, and jury. Now that the trial is over, it is important to me to provide transparency," he said. 

One image shows Anthony's hands cuffed following the deadly incident while sitting in the back of a police vehicle with what appears to be blood on his left hand. 

Metcalf's father, Jeff Metcalf, previously told Fox News Digital that surveillance footage of his son's fatal stabbing would contradict many of the claims that circulated online after the deadly confrontation at a Texas track meet.

Now, with Collin County releasing trial exhibits presented to jurors, the public is getting its first look at evidence shown during Anthony's murder trial.

Metcalf, who viewed the footage before it was played in court, said he believed its release would answer lingering questions about what happened beneath the Memorial High School team tent the day of the murder. 

"The video clearly shows the conversation lasted less than 10 seconds. That's it," Metcalf previously told Fox News Digital. "There was no four-on-one."

Metcalf said the footage contradicts claims that Anthony was jumped, surrounded or attacked by multiple students before the stabbing.

"He wasn't jumped. There was no four-on-one. He wasn't surrounded," Metcalf 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."
