FRISCO, TX — A 17-year-old student accused of fatally stabbing another teenager at a Texas track meet allegedly told police he was protecting himself, according to an arrest report. Officers say the suspect also admitted, “I did it,” after being identified as the alleged attacker at a Frisco Independent School District stadium on Wednesday morning.

Authorities say the stabbing happened during a track and field championship involving several high schools in the district. The victim, 17-year-old Austin Metcalf, was a junior at Frisco Memorial High School and died after the confrontation in the bleachers. Police have charged Karmelo Anthony, a student at Frisco Centennial High School, with first-degree murder.

Witness accounts describe a tense exchange under the Memorial High School tent

According to the arrest report, the confrontation began after Metcalf told Anthony to move from under the Memorial High School tent. A witness reported that Anthony then reached into his bag and warned, “Touch me and see what happens,” before the altercation escalated.

The same witness said Metcalf grabbed Anthony in an effort to move him. Police say Anthony then pulled out what was described as a black knife, stabbed Metcalf once in the chest and ran away. Officers later recovered a bloody knife in the bleachers. The stabbing took place around 10 a.m., while the meet was underway at the stadium in Frisco.

Police say the suspect made several spontaneous statements after the stabbing

One officer wrote in the arrest report that Anthony began talking about the incident before being questioned. The suspect allegedly said, “I was protecting myself,” and later responded, “I’m not alleged, I did it,” after an officer referred to him as the alleged suspect.

As he was taken toward a squad car, Anthony was described as emotional. Police say he also said, “He put his hands on me, I told him not to,” and asked whether Metcalf was going to be OK. Another officer reported that Anthony asked if what happened could be considered self-defense while he was being escorted away from the stadium.

Austin Metcalf was pronounced dead at a nearby hospital

Emergency crews took Metcalf to a local hospital after the stabbing, and he was pronounced dead at 10:53 a.m., according to the arrest report. Police say the student was attacked in the bleachers during the meet and died shortly after the stabbing.

His twin brother, Hunter Metcalf, was also at the event and later spoke with officers at the scene. He said the argument began after Austin told Anthony he had to leave the tent because he did not attend Memorial. Hunter told WFAA that the confrontation quickly turned physical and that he did not see the knife come out.

Family members and witnesses described a fast-moving confrontation

Hunter Metcalf said the exchange started as a disagreement over where Anthony was standing. In the arrest report, he told officers that the two went back and forth before Austin stood up and pushed the other student to get him out of the tent.

In his comments to WFAA, Hunter Metcalf said the killing felt senseless and hard to understand. He said he could not see the stabbing itself and questioned why someone would react so violently during what began as a small argument. The account adds another witness perspective to the sequence described in the police report.

The accused student is being held on one million dollar bond

Court records show Anthony is being held in the Collin County jail on $1 million bond. His attorney told ABC News on Friday that he had only recently taken the case and needed time to catch up. Anthony’s father said on Thursday that the family did not have a statement at that time.

The criminal case is still in its early stages, and police have not said anything publicly beyond the arrest report and charge. The stabbing has already disrupted the school community and left questions about safety at large athletic events, even as the legal process moves forward.

Track meet postponed as Frisco ISD plans new security details

The track meet has been postponed until Monday and moved to a different location, according to WFAA. Frisco ISD also plans to share more information with families about updated security measures before the event resumes.

The district has not yet detailed those changes publicly, but the postponement shows the immediate effect of the killing on the championship and the schools involved. The fatal stabbing, which happened in front of athletes, coaches and spectators, has prompted a broader focus on safety as the community prepares for the revised meet.
