Karmelo Anthony Was Ordered to Leave Opposition Team’s Tent At Least 15 Times Before He Pulled Knife and Stabbed Austin Metcalf, Witness Claims

High school track athlete Karmelo Anthony was reportedly told 15 times to leave a tent designated for a rival team but allegedly refused, according to testimony from a witness on Friday. The witness said the confrontation ultimately led to the fatal stabbing of fellow teenager Austin Metcalf last year.

A 17-year-old student from Frisco Memorial High School testified that he and several teammates were gathered under their school’s team tent when he noticed Anthony standing in the area wearing apparel from rival Frisco Centennial High School. The witness said Memorial students began telling Anthony, “You probably shouldn’t be here, you need to leave our tent,” before the deadly attack started.

Everything Going Against Killer

The student’s name was not revealed in court because he is a minor. According to the teen’s testimony, several Memorial teammates — including Metcalf, then 17— asked Anthony, who was also 17 at the time, to leave the tent about 15 times. Anthony allegedly replied, “Touch me and find out,” while the exchange unfolded at Kuykendall Stadium.

The witness said the confrontation lasted about two minutes before Metcalf gave Anthony what he described as a “minor push.” Anthony then allegedly pulled out a knife and stabbed Metcalf.

The witness testified that, before the stabbing, Anthony had his hand inside an open backpack resting on his lap. However, the students believed he was only bluffing and did not think he actually had a weapon.

After the stabbing, Anthony allegedly threw away the knife and ran down the stadium stands toward the track.

The teen told jurors that Metcalf initially fell onto his back but then got up and lifted his shirt while leaning against a railing. He said Metcalf appeared terrified as he noticed blood coming from his chest. “I think he said, ‘Oh my God,'” the witness recalled.

No Way Out for Anthony

Jurors also head a 911 call placed by the teen, during which he could be heard desperately telling the dispatcher, “My friend just got stabbed. My friend is bleeding everywhere.” The witness denied suggestions that the Memorial students had “ganged up” on Anthony, maintaining instead that Anthony was the one who “created a problem.”

Jalen Matthews, 18, a former teammate of Metcalf who has since graduated, testified that during the confrontation, Austin’s twin brother, Hunter, was occupied with his phone and believed Austin could handle the situation on his own.

Matthews recalled one Memorial student telling Anthony, “You have nothing in the backpack, you’re from Frisco.”

Anthony appeared to be staring off into the distance and seemed as though he had already made up his mind about what he was going to do, according to Matthews. He testified that Metcalf pushed Anthony upward in a manner similar to a football lineman drill. At the same moment, Anthony rose to his feet and stabbed Metcalf.

Matthews told the jury that, in his view, the stabbing did not appear to be an act of self-defense because Metcalf was not threatening Anthony. He described Anthony as the person who initiated the confrontation.

Earlier in the day, jurors were shown body camera footage capturing the aftermath of the stabbing. In the video, Hunter Metcalf could be heard crying and screaming moments after his twin brother was wounded.

Anthony’s defense lawyer, however, argued that Metcalf had provoked Anthony and maintained that the April 2, 2025, stabbing was an act of self-defense.

Anthony has pleaded not guilty to the charges. If he is ultimately convicted, he could face a sentence of up to life in prison.
