Jury found Karmelo Anthony guilty of murder, turning a high-profile school stabbing case into a sharp warning about violent crime, self-defense claims, and courtroom accountability.
Quick Take
- A Collin County jury found Karmelo Anthony guilty of murder in the death of Austin Metcalf.[1]
- Jurors heard testimony from dozens of witnesses before reaching the verdict.[1]
- The judge allowed jurors to consider manslaughter, but they still chose murder.[1][2]
- Coverage from the courtroom said the jury rejected the self-defense claim.[3]
Verdict Ends a Closely Watched Trial
A Collin County jury convicted Karmelo Anthony of murder in the fatal stabbing of 17-year-old Austin Metcalf at a Frisco Independent School District track meet.[1] The case drew national attention because it involved two teenagers, a school sports event, and a self-defense claim that failed to persuade jurors. Prosecutors argued Anthony intentionally stabbed Metcalf during an altercation, while the defense said Anthony reacted to a threat.[1][2]
The verdict came after jurors heard from dozens of witnesses, including students who saw the confrontation, law enforcement investigators, medical experts, and defense character witnesses.[1] ABC News reported that the stabbing happened on April 2, 2025, at a Frisco stadium during a track and field competition.[2] The jury also had the option to return a manslaughter verdict, but it chose murder instead.[1][2]
Self-Defense Argument Did Not Carry the Day
The defense built its case around a fast-moving confrontation that it said started after Anthony was told to leave the area.[3][4] Court coverage and trial reporting said the defense pointed to a shove or push before the stabbing and argued that Anthony feared harm.[3][4] That version of events was central to the self-defense claim, but the jury rejected it after weighing the testimony and evidence.[3]
During live courtroom coverage, reporters said Lori Brown announced, “we the jury find the defendant guilty of murder.”[3] Commentators on that stream said the verdict showed jurors had rejected the self-defense theory and believed the use of deadly force was excessive.[3] ABC 7 Chicago also reported that prosecutors told jurors the case was “murder plain and simple” and argued Anthony was the aggressor.[4]
What the Case Signals for Texas Jurors
The verdict shows how sharply Texas juries can draw the line between self-defense and unlawful force in close-range violent cases.[1][2][4] Prosecutors said Anthony provoked the encounter, while the defense said he acted out of fear.[2][4] Judge John Roach allowed jurors to consider manslaughter as a lesser option, but the murder conviction shows they accepted the state’s stronger version of events.[1][2]
Yes, clips of the grainy surveillance footage (Frisco ISD cameras, enhanced in court) from the track meet have circulated on X. Posts include news/analysis videos showing the confrontation, Metcalf’s push, and Anthony’s actions. Full raw multi-angle raw footage isn’t widely…

The case also landed inside a wider public fight over school safety, teenage violence, and the fear that violent acts can erupt in places where families expect order.[1] For readers worried about declining discipline and rising danger, the verdict offers a simple lesson: a jury decided this was not a justified act of self-defense. The punishment phase will now determine Anthony’s sentence, which could be severe under Texas law.[1][2]
