A Texas jury needed just three hours to decide that a knife, a shove, and a self-defense claim did not add up to innocence.
Story Snapshot
- Karmelo Anthony, 19, was found guilty of murder on June 9, 2025, for stabbing 17-year-old Austin Metcalf at a Frisco, Texas, high school track meet.
- Anthony never denied the stabbing but argued self-defense, saying Metcalf shoved him first.
- The jury rejected that claim after roughly three hours of deliberation and moved straight to sentencing.
- A Texas legal doctrine called “sudden passion” could still reduce Anthony’s sentence in the penalty phase.
A Track Meet Turned Fatal in April 2025
On April 2, 2025, students from across the Frisco Independent School District gathered for a district-wide track meet. During a rain delay, Karmelo Anthony walked under a tent belonging to a rival team. Words were exchanged.
Austin Metcalf, 17, was stabbed and died from his wounds. Anthony surrendered to police shortly after. From the start, the case was never about who held the knife. It was always about whether using it was justified. [8]

Anthony pleaded not guilty and claimed self-defense. His defense team argued that Metcalf provoked the fight and put hands on Anthony first. Body-camera footage captured Anthony telling officers, “He put his hands on me. I told him not to.”
A former teammate testified Anthony was crying and visibly shaken right after the stabbing. The defense also argued Anthony was not trespassing under the rival team’s tent and that Metcalf started the confrontation. [2][3]
What the Prosecution Built Its Case On
Prosecutors painted a different picture. Student witnesses testified that Anthony was asked to leave the area, refused, and made threatening remarks before the stabbing.
The phrase “Touch me and see what happens” was reported as part of the exchange. Witnesses said the violence seemed to come out of nowhere. Importantly, Anthony chose not to testify, which left the jury without a direct account of what he says he feared in that moment. [3][15]
The prosecution’s position was straightforward: a shove does not justify a fatal stabbing. Even if Metcalf made physical contact, the response was wildly out of proportion. The jury agreed.
Judge John Roach allowed jurors to consider a lesser charge of manslaughter, giving them a middle path. They did not take it. They returned a murder verdict. [1][2]
Three Hours to a Verdict
Juries in high-profile murder cases sometimes deliberate for days. This one took about three hours. That speed is worth noting. It suggests the panel did not find the self-defense argument close.
The video evidence from the scene was described as unclear, so the verdict rested heavily on eyewitness testimony and the sequence of events leading up to the stabbing. [3][6] Short deliberations in murder cases usually mean the jury found one side’s story far more believable than the other’s.
Crowds clashed outside the Collin County Courthouse after the verdict was announced. The case had drawn national attention and sparked heated debate about race, self-defense laws, and school safety.
Concerns were raised during the trial about the racial makeup of the jury after Black jurors were reportedly struck during selection. Those debates did not change the outcome, but they guaranteed the verdict would be received very differently depending on who was watching. [10][1]
Sentencing and the “Sudden Passion” Question
Under Texas law, a defendant convicted of murder can argue “sudden passion” during the penalty phase. If the jury accepts that argument, the charge drops from a first-degree felony to a second-degree felony. That shift matters enormously.
A first-degree murder conviction in Texas carries five to 99 years in prison. A second-degree conviction carries two to 20 years. Anthony’s mother reportedly asked the jury for mercy during the sentencing phase. [4]
The sudden passion argument is essentially a second bite at the emotional apple. It asks the jury to accept that Anthony acted out of intense fear or rage caused by Metcalf’s conduct, even if that reaction went too far.
Whether the same jury that rejected self-defense in three hours will show leniency on punishment is the last open question in this case. The facts as presented at trial suggest they saw an aggressor, not a frightened kid. That framing will be hard to reverse at sentencing. [4][2]
