The suspect, 17-year-old Karmelo Anthony, was taken into custody and charged with murder, according to police in Frisco, about 30 miles (50 kilometers) north of Dallas.
The Frisco Independent School District said the stabbing happened at a meet where student athletes from eight of the district’s 12 schools were competing.
The student who was killed was Austin Metcalf, an 11th grader at Memorial High School, according to an email the principal sent to parents Wednesday.
In a probable cause affidavit reviewed by Court TV, police said that they were dispatched to the stadium where the meet was being held and were immediately pointed toward Anthony, who was standing on the track behind a chain-link fence. As officers asked him to put his hands in the air, he responded, “I was protecting myself.”

Police did not find any weapons as they searched Anthony, who told officers “he put his hands on me.” As he was placed in handcuffs and an officer advised that the alleged suspect was in custody, Anthony said, “I’m not alleged. I did it.” Walking to the patrol car, Anthony continued to make statements, including, “He put his hands on me, I told him not to,” and “Is he going to be okay?”
One of Metcalf’s teammates, who witnessed the stabbing, told officers at the scene that Anthony, who attends a different school, was under their team’s tent. Metcalf allegedly told Anthony he needed to move out from under the tent, prompting Anthony to grab his bag, open it, reach inside and say, “Touch me and see what happens.”
The witness said that Metcalf touched Anthony, who then told Metcalf to punch him. A short time later, the witness said Anthony pulled out a “black knife” and stabbed Metcalf once in the chest before running away. The witness said Metcalf grabbed his chest and asked for help.
A witness at the scene helped officers locate the knife, which was found on the bleachers.
