New testimony presented on Saturday has raised questions about Karmelo Anthony’s claim that he acted in self-defense when he fatally stabbed 17-year-old Austin Metcalf in the chest.

According to eyewitness accounts presented in court, several witnesses stated that Anthony, 19, appeared to have provoked the confrontation before the deadly incident occurred.

One key witness, a 17-year-old student-athlete who attended Frisco Memorial with Metcalf, testified that Anthony did not act in self-defense. The witness told the court that Anthony kept his hands inside his backpack until Metcalf shoved him, at which point Anthony allegedly responded by stabbing the teenager in the chest.

The witness emphasized what he viewed as a critical distinction in the encounter, describing the response as disproportionate to the threat presented.

“That’s lethal force against non-lethal,” the student testified.

The testimony could prove significant as the case moves forward, particularly because Anthony’s defense has centered on the claim that he was protecting himself during the confrontation. The eyewitness account offers a different version of events, one that prosecutors and investigators will likely examine closely as proceedings continue.

The fatal stabbing shocked the local community and has drawn widespread public attention. As additional testimony emerges, the court will be tasked with determining exactly what happened in the moments leading up to Metcalf’s death.

For now, the latest witness statements have added another layer to a closely watched case and intensified scrutiny of the self-defense argument. Because when eyewitnesses present a version of events that differs from the defense's narrative, it tends to generate more questions than answers.

As the legal process continues, both sides will have the opportunity to present evidence, with the ultimate facts of the case to be determined in court.
