Karmelo Anthony Convicted of Murder and Sentenced to 35 Years After Lightning-Fast 3-Hour Verdict: Jury Rejects Self-Defense Claim

Frisco, Texas — In a verdict delivered with remarkable speed, a Collin County jury on June 9, 2026, convicted 19-year-old Karmelo Anthony of murder and sentenced him to 35 years in prison for fatally stabbing 17-year-old Austin Metcalf during a high school track meet, decisively rejecting his self-defense claim under Texas’s Stand Your Ground law.

The April 2, 2025, confrontation at the Frisco ISD stadium bleachers began as a verbal dispute between rival athletes. Anthony, a Black student from Centennial High School, admitted plunging a knife into Metcalf’s chest after being shoved. Prosecutors proved he provoked the fight, issued threats, and escalated the clash into lethal violence. Multiple eyewitnesses—including Black athletes from the opposing team—testified that Anthony entered the rival tent uninvited and turned a heated argument ᴅᴇᴀᴅly. Anthony’s own statements to police that he was “protecting myself” were used against him.

The jury needed less than three hours to convict on murder rather than the lesser manslaughter charge. In the punishment phase, they rejected a “sudden pᴀssion” argument that could have capped the sentence below 20 years, opting for 35 years out of a possible 5–99 range. Anthony faces up to 17.5 years before parole eligibility; his defense team immediately filed an appeal.

The case has exposed deep divisions. The 12-person jury contained no Black members after prosecutors used peremptory strikes to remove every qualified African American candidate from a 589-person pool, citing non-racial reasons such as occupation or perceived bias. The defense raised unsuccessful Batson challenges. Collin County DA Greg Willis insisted, “This case has nothing to do with race. It is about the evidence, the law, and accountability for a deliberate act of violence.” Anthony’s mother maintained her son acted in self-defense after being pushed first. Metcalf’s family called the outcome “bittersweet,” noting, “Austin will never walk through that door again.”

The lightning-fast deliberation and overwhelming eyewitness testimony—including from Black witnesses—underscore how the jury viewed the stabbing as unjustified aggression rather than reasonable fear. As Anthony begins his sentence and appeals proceed, the Frisco tragedy continues to fuel national debate over self-defense laws, teen violence, and jury fairness in racially charged cases.
