Jury hears account of what Dallas teen accused of track-meet stabbing allegedly said: 'I did it.'

The second day of a murder trial continued on Friday in the murder trial of Karmelo Anthony, a teenager who is accused of stabbing to death Austin Metcalf at a track meet in a Dallas suburb in April 2025. 

Anthony maintains that he acted in self-defense in the case, which has drawn national attention due to the race of Anthony, who is Black, and the race of Metcalf, who is White. 

Collin County prosecutor Bill Wirskyke told jurors that the stabbing had nothing to do with race. Instead, he called it a "provoked unjustifed murder" that was not about self-defense.

Prosecutors called a Frisco school resource officer, Eduardo Cortez, who was among the first responders at the scene of the stabbing, Fox News reported. Cortez told jurors that he handcuffed Anthony who told him, "I'm not alleged, I did it." Cortez said he hadn't asked the teen any questions. 

Cortez also said the school district prohibits weapons on school property, and Cortez testified that he never encountered a student who had one. 

Jurors also saw body-camera footage in which Anthony appeared emotional and stated repeatedly that Metcalf had put his hands on him. 

The incident took place in the affluent Dallas suburb of Frisco. Witnesses say that Anthony and Metcalf had an altercation after the victim told Anthony he was sitting in the wrong area. 

The witnesses told local police that Metcalf grabbed Anthony at one point in the altercation to get him to move after Anthony reportedly dared him. Anthony then allegedly pulled a knife on Metcalf and stabbed him once in the chest before running away, the Daily Wire reported.
