Two teens involved in a deadly stabbing at a Texas high school track meet on April 2 had no prior connection, according to witnesses.
Karmelo Anthony, 17, is accused of stabbing Austin Metcalf, 17, in the heart last week while both were at the Kuykendall Stadium in Frisco. Both teens were attending a championship track and field meet.
A probable cause affidavit obtained by CrimeOnline indicated that witnesses told police the confrontation started when Metcalf asked Anthony to leave a tent set up for Metcalf’s track team.
The affidavit stated that the two had never met before the incident.
Police said Metcalf got into an altercation with Anthony, who sat under a tent designated for Memorial High School students.
Metcalf was a junior football star at Memorial, while Anthony attended Centennial High School. The affidavit stated that after Anthony reached into his bag upon being told he was sitting in the wrong area.
A witness reported hearing him say, “Touch me and see what happens.”
The witness told police that Metcalf then touched Anthony, who then encouraged Metcalf to punch him. Metcalf reportedly tried to make him move. That’s when Anthony pulled a black knife from his bag and stabbed Metcalf in the chest before fleeing, the witness said.
Anthony later asked police if the incident constituted self-defense.
“I know that my client said it was self-defense. I don’t have any reason to disbelieve that, but I need to develop facts, talk to people and figure out what’s going on before I make any statements about what I think happened,” Anthony’s defense lawyer, Deric Walpole, told NBC 5. “I don’t have any reason to think it wasn’t self-defense at this time.”
Meanwhile, the Frisco Police Department is warning the public of social media posts spreading fraudulent information.
“Beware of those taking to social media to deliberately spread misinformation, hate, fear and division,”Frisco Police Chief David A. Shilson posted on X., stating someone called the incident a “mutual combat altercation” after Metcalf “sucker punched” Anthony.

The chief goes on to say that the same fraudulent account claimed Metcalf also smashed Anthony’s phone “onto one of the bleachers.”
The source behind the account could face impersonation charges, a third-degree felony. Police are currently investigating the incident.
Police also said a doctored image, which falsely claimed to be a report from the Collin County Medical Examiner’s Office, stated that Metcalf’s primary cause of death was an “MDMA drug overdose,” with the stab wound listed as a secondary cause.
Metcalf’s cause of death has not yet been released.
“The Frisco Police Department is aware of an image circulating on social media purporting to be a report from the Collin County Medical Examiner’s Office. At this time, the report has NOT been released. Therefore, any information currently found online is FALSE,” the police department said.
Anthony remains behind bars on $1 million bail. Check back for updates.
