COLLIN COUNTY — For more than 14 months, the fatal stabbing of Frisco Memorial High School student Austin Metcalf has been the subject of intense debate across Collin County and far beyond.
The case generated national headlines, online fundraising campaigns, social media battles, protests and endless arguments over what happened beneath a rain-soaked team tent at a Frisco ISD track meet.
Karmelo Anthony was found guilty of murder in the April 2, 2025 stabbing death of Metcalf. Later the same day, jurors sentenced the 19-year-old to 35 years in prison.
The verdict closes one chapter in a case that began with a brief confrontation at a Frisco ISD track meet and ended Tuesday with a sentence that will shape lives for decades.
The Seconds That Led Here
What happened beneath a team tent at Kuykendall Stadium took less time than it took jurors to read their verdict Tuesday afternoon.
Testimony showed the confrontation began during a rain delay at a Frisco ISD track meet.
Anthony, then a student at Frisco Centennial High School, entered a Memorial High School team tent as athletes sought shelter from the weather. An argument followed.
Witnesses offered differing accounts about exactly what was said and how the confrontation unfolded. Jurors heard testimony about physical contact, verbal exchanges and the events leading up to the stabbing.
What was not disputed was the outcome.
Austin Metcalf suffered a stab wound to the chest.
Despite emergency efforts at the scene, the 17-year-old died from his injuries.
Anthony was arrested and charged with murder. From the beginning, his attorneys maintained he acted in self-defense.
More than 14 months later, that claim became the central question jurors were asked to decide.
Jury Hears Two Different Stories
Throughout the trial, prosecutors and defense attorneys presented sharply different interpretations of what occurred beneath the tent.
Defense attorney Mike Howard argued Anthony found himself in a rapidly escalating confrontation and was forced to make a split-second decision.
Howard urged jurors to view the encounter through the eyes of a frightened teenager. He pointed to inconsistencies in witness testimony and argued Anthony believed he needed to defend himself.
Prosecutors argued the evidence pointed somewhere else.
They contended Anthony escalated the confrontation and responded to a non-deadly encounter with deadly force.
During closing arguments, prosecutor Bill Wirskye told jurors that self-defense requires a proportional response and argued the evidence did not support Anthony’s claim.
“This is unjustified, provoked murder,” Wirskye said.
After several hours of deliberation, the jury sided with the prosecution.
The Moment the Case Turned
Shortly after 2:30 p.m. Tuesday, jurors returned to the courtroom.
Anthony stood beside his attorneys as family members from both sides filled the gallery.
When the verdict was read, Anthony’s mother began to cry.
The jury found Anthony guilty of murder.
Proceedings quickly shifted to the punishment phase, where jurors would decide how many years Anthony would spend in prison.
The Fight Over Punishment
The defense sought leniency.
Anthony’s mother took the witness stand and pleaded with jurors to show mercy toward her son.
Defense attorneys also argued Anthony acted under what Texas law describes as sudden passion, a finding that could have significantly reduced the punishment range.
Prosecutors urged jurors to reject that argument.
Instead, they focused on the impact of Metcalf’s death and argued the evidence did not support a sudden passion finding.
As deliberations continued, both families waited for a second decision — one that would determine how many years Anthony would spend in prison.
Shortly after 7:30 p.m., jurors returned.
Anthony was sentenced to 35 years in prison.
The panel also rejected the sudden passion claim.
A Verdict That Ends One Debate, Not Another
The jury had several options.
It could have acquitted Anthony, convicted him of a lesser offense or reduced his punishment through a finding of sudden passion.
Instead, jurors convicted him of murder and sentenced him to 35 years in prison.
Appeals are expected, and public debate will continue.
But after seven days of testimony, twelve Collin County jurors reached a conclusion.
The confrontation lasted only moments.
The consequences will likely last a lifetime.
