• Karmelo Anthony has been indicted on first-degree murder in the April 2025 fatal stabbing of Austin Metcalf at a track meet
• Both high school students were 17 years old at the time of the incident
• “I was protecting myself,” the accused told police after a physical altercation led to the fatal stabbing

The Texas teen accused of fatally stabbing a fellow student at a high school track meet in April has been indicted for first-degree murder.

On Tuesday, June 24, Collin County District Attorney Greg Willis announced Karmelo Sincere Anthony was indicted by a grand jury for the April 2, 2025, stabbing death of Austin Metcalf during a high school track meet in Frisco.

Both boys were 17 at the time of the incident. The Texas criminal justice system considers 17-year-olds to be adults.

Willis described Metcalf’s death as a “violent loss” that left their community “shaken by what happened.”

“For weeks, my team has been presenting evidence to the grand jury. Today, I summarized that evidence, and I asked the Grand Jury to return a first degree murder indictment against Karmelo Anthony — which they did,” the district attorney said.

Next, the case will be taken to court for trial

“We know this case has struck a deep nerve — here in Collin County and beyond. That’s understandable. When something like this happens at a school event, it shakes people to the core,” Willis said. “But the justice system works best when it moves with steadiness and with principle. That’s what we’re committed to. And that’s exactly what this case deserves.”

He continued, “We’re also mindful of Austin’s family, and everyone who loved him. Please keep them in your thoughts — and, if you’re willing, in your prayers as well.”

Willis added that “a defendant is presumed innocent unless and until proven guilty in a court of law.”

Anthony has been out of custody after posting $250,000 bail.

According to a copy of the probable cause affidavit in the case previously obtained by PEOPLE, an eyewitness told police that Metcalf allegedly asked Anthony to move out from under a tent at Kuykendall Stadium that was set up for members of his high school track team on the field that rainy day.

“Touch me and see what happens,” Anthony allegedly told Metcalf while reaching into his backpack.

The eyewitness claimed that Metcalf touched Anthony, at which point, Anthony allegedly told him to punch him and see what happens, according to the affidavit.

When Metcalf went to physically move Anthony, Anthony allegedly pulled a knife out of his bag, stabbed Metcalf in the chest and fled from the tent, per the affidavit.

Anthony allegedly told responding officers, “I was protecting myself,” per the affidavit.

When the officer referred to Anthony as an “alleged suspect,” he seemingly admitted to the crime in response, allegedly saying, “I’m not alleged, I did it,” according to the affidavit.

“He put his hands on me. I told him not to,” Anthony told a police officer at one point, also asking authorities “if what happened could be considered self-defense,” the affidavit states.
