The high-profile murder trial surrounding the fatal stabbing of Texas teenager Austin Metcalf has reached a major turning point. A Collin County jury has found 19-year-old Karmelo Anthony guilty of first-degree murder, concluding a case that has drawn national attention since the deadly incident at a school track meet in 2025.
The verdict was delivered on June 9, 2026, after jurors spent approximately three hours deliberating. The decision now shifts the focus of the courtroom proceedings to sentencing, where Anthony faces the possibility of spending decades behind bars.
Jury Reaches Unanimous Verdict
The trial took place at the Collin County Courthouse in McKinney, Texas, and lasted four days. Prosecutors and defense attorneys presented competing versions of what happened during a confrontation between Anthony and 17-year-old Austin Metcalf at a regional track event.
After reviewing testimony from witnesses and examining evidence presented during the trial, the 12-member jury unanimously convicted Anthony of first-degree murder. Jurors were also given the option of considering a lesser manslaughter charge, but ultimately chose the more serious conviction.
The ruling marks a significant moment in a case that has been closely followed across Texas and beyond.
What Happened at the Track Meet?
The deadly encounter occurred on April 2, 2025, during a rainy regional track and field competition held at Kuykendall Stadium in Frisco.
According to testimony presented in court, the dispute began under a stadium tent used by students from Frisco Memorial High School. Anthony, a student from Centennial High School, was reportedly asked several times to leave the area.
Witnesses described a verbal confrontation that lasted several minutes. The disagreement eventually became physical when Metcalf allegedly shoved Anthony during the exchange.
Moments later, Anthony pulled out a pocketknife and stabbed Metcalf in the chest. Emergency responders transported the injured teenager to a nearby hospital, where he was later pronounced dead.
The incident shocked students, parents, and the wider community, quickly becoming one of the most discussed criminal cases involving teenagers in Texas.
Defense Argued Self-Defense
Throughout the trial, Anthony’s legal team maintained that the stabbing was not a planned attack but a reaction to a rapidly escalating situation.
Defense attorney Mike Howard argued that his client acted in fear after being physically confronted. According to the defense, Anthony made a split-second decision while facing what he perceived as a threat from a larger athlete.
Anthony chose not to testify during the proceedings, a legal right available to criminal defendants. His attorneys focused on persuading jurors that the circumstances justified a self-defense claim.
The defense also sought to convince the jury that the evidence supported a lesser offense rather than murder.
Prosecutors Rejected Justification Claim
Prosecutors presented a sharply different interpretation of events.
The state argued that Anthony was responsible for escalating the conflict and emphasized that he brought a concealed knife to a school sporting event. Prosecutors told jurors that Metcalf was unarmed and that the response to a shove was grossly disproportionate.
During closing arguments, the prosecution insisted that the stabbing was neither necessary nor legally justified. They portrayed the attack as an intentional act that directly resulted in the death of another teenager.
The jury ultimately agreed with the prosecution’s position, leading to the first-degree murder conviction.
Racial Issues Added Public Attention
The case generated widespread discussion beyond the courtroom because of racial concerns raised during jury selection.
Anthony is Black, while Metcalf was white. Before opening statements began, defense attorneys challenged the prosecution’s jury selection process, arguing that Black prospective jurors had been removed from consideration.
Prosecutors responded that their decisions were based on race-neutral factors, including concerns about certain occupations and backgrounds among potential jurors.
After reviewing the arguments, Judge John Roach Jr. allowed the jury panel to remain in place. The final jury consisted entirely of white jurors, a development that fueled debate and attracted significant media coverage throughout the trial.
Sentencing Phase Now Begins
Although Anthony has been convicted of first-degree murder, the legal process is not yet complete.
The case has now entered the sentencing phase, where jurors will decide the punishment. Because Anthony was 17 years old when the stabbing occurred, he cannot receive the death penalty under longstanding U.S. Supreme Court precedent regarding juvenile offenders.
Under Texas law, the available sentencing range is broad. Anthony could receive a prison term as short as five years or as long as 99 years. A life sentence is also possible.
During sentencing proceedings, both prosecutors and defense attorneys are expected to present additional evidence and arguments concerning Anthony’s background, character, and the circumstances surrounding the crime.
A Case That Captured National Attention
The death of Austin Metcalf and the prosecution of Karmelo Anthony became one of the most closely watched criminal cases involving teenagers in recent years. The trial combined questions of self-defense, youth violence, school safety, and race, drawing attention from communities across the country.
With the guilty verdict now delivered, the focus turns to determining Anthony’s punishment. Whatever sentence is ultimately imposed, the case has already left a lasting impact on the families involved and on the Texas communities that followed every stage of the proceedings.
