Karmelo Anthony, the teenager accused of fatally stabbing Austin Metcalf at a Frisco high school track meet, has been indicted for murder, officials said.
A Collin County grand jury indicted the 17-year-old on a charge of first-degree murder on Tuesday, according to the Collin County District Attorney’s Office. The charge stems from the fatal stabbing of Metcalf, also 17, during a high school track meet at Frisco ISD’s Kuykendall Stadium on April 2.
A conviction for murder in Texas carries a sentence of 5 to 99 years, or life in prison.
"We know this case has struck a deep nerve — here in Collin County and beyond," Collin County District Attorney Greg Willis said in a statement Tuesday. "That’s understandable. When something like this happens at a school event, it shakes people to the core. 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."
What happened during the fatal stabbing of Austin Metcalf?
Records show the altercation between Metcalf and Anthony occurred around 10 a.m. Police say the two were involved in a disagreement over a seat at the track meet before Anthony wielded a knife and stabbed Metcalf in the heart.
In initial investigations, one witness told authorities that he was sitting under a Memorial High School tent with the team while Metcalf, who is a student at Memorial, and Anthony were sitting nearby. Anthony was sitting under the team’s tent when Metcalf told him he needed to move, the witness said, according to the initial affidavit.
"Anthony grabbed his bag, opened it and reached inside and proceeded to tell (Metcalf) ‘Touch me and see what happens,’" the affidavit said.
Metcalf touched Anthony, who then told Metcalf to punch him and see what happens, the witness said. Metcalf then grabbed Anthony to tell him to move again, and that’s when Anthony pulled out a knife and stabbed Metcalf once in the chest before running away, according to the affidavit.
Metcalf began grabbing his chest and telling people to get help, the affidavit said.
Athletic trainers told first responders that Metcalf was not conscious and not breathing, according to the arrest warrant affidavit obtained by USA TODAY. First responders performed lifesaving measures on the wounded victim, from CPR to blood administration, but the teen died at the scene.
Karmelo Anthony and attorney claims ‘self-defense’ in fatal stabbing
The perpetrator admitted to the stabbing at the scene, claiming self-defense, the Austin American-Statesman previously reported.
"I was protecting myself," Anthony allegedly said, unprovoked, when Cortez told him to keep his hands in the air. The officer then communicated to others that he had the alleged suspect in custody, to which Anthony said, "I'm not 'alleged.' I did it."
Despite Tuesday’s indictment, Anthony’s attorney, Mike Howard, said it was "an expected and routine step in the legal process."
"Karmelo and his family are confident in the justice system and the people of Collin County to be fair and impartial," Howard said. "Of course, Karmelo looks forward to his day in court. It's only in a trial that a jury will hear the full story, one that includes critical facts and context that the grand jury simply didn't get to hear."
He added that he expects, once the incident is explained in its entirety, that the prosecution will rule otherwise.
"We expect that when the full story is heard, the prosecution will not be able to rule out the reasonable doubt that Karmelo Anthony may have acted in self defense," Howard said in a statement. "Self defense is a fundamental right guaranteed every American."
