Murder trial underway for Texas teenager accused of fatally stabbing athlete
DALLAS -- Opening statements were set for Thursday in the murder trial of a former Texas high school athlete accused of taking out a knife during a track meet and fatally stabbing a 17-year-old competitor from a rival team in the stadium's bleachers.
The killing last year stunned an affluent Dallas suburb where the teenagers attended school and quickly drew wider attention, in part over social media posts that amplified the case in racial terms.
Karmelo Anthony, now 19, faces up to life in prison if convicted in the killing of Austin Metcalf. According to an arrest report, Anthony told police he was protecting himself when the teenagers got into a confrontation during a high school track meet in Frisco, a booming city in Dallas' sprawling north suburbs.
A jury was seated this week under increased security at a Collin County courthouse and a judge has set strict rules over the proceedings, including prohibiting attorneys from discussing the case publicly.
“We know this case has struck a deep nerve — here in Collin County and beyond,” Collin County District Attorney Greg Willis said while announcing the indictment against Anthony last year.
The stabbing happened on a rainy morning in April 2025. Witnesses told police the confrontation began when Anthony sat under a tent belonging to Metcalf's team, according to an arrest report. The teens went to different high schools in Frisco.
When Metcalf told Anthony that he needed to move, Anthony reached inside his bag and allegedly replied: “Touch me and see what happens,” the report said.
A short time later, Metcalf allegedly grabbed Anthony, who then pulled out a knife and stabbed the other teenager in the chest, the report said.
A police officer said in the report that Anthony told him that Metcalf had put his hands on him, and that he was protecting himself.
Mike Howard, Anthony's attorney, said following the indictment last summer that he expects prosecutors would “not be able to rule out the reasonable doubt” that his client may have acted in self-defense once the full details of the confrontation come out.
The parents of both teens have said they were good students who planned to go to college.
Metcalf's father has condemned those who have seized on the race of the teenagers after the killing. Anthony is Black; Austin Metcalf was white.
“This was not a race thing. This is not a political thing. Please do not comment if you do not know what happened,” Metcalf’s father, Jeff Metcalf, said on Fox News' “America Reports.”
“This is a human being thing,” he said. “This person made a bad choice and it affected both his family and my family forever.”
Authorities have also issued warnings about online discussions surrounding the killing. Frisco Police Chief David Shilson has urged people to beware of posts spreading “misinformation, hate, fear, and division.”'
