Anthony stands accused of stabbing Austin Metcalf, 17, in the chest at a track meet. Metcalf reportedly died in his twin brother’s arms.

Opening arguments are underway in the murder trial of a Texas teenager accused of stabbing a fellow high schooler at a track meet.

Karmelo Anthony, 19, was arrested last year and charged with stabbing Austin Metcalf, 17, during an altercation at a track meet at a Frisco high school, a sprawling suburb of Dallas.

Opening statements began Thursday morning at the Collin County courthouse. The jury was seated earlier this week.

The case has drawn national attention amid an explosive online debate along racial lines. Anthony is Black; Metcalf was white.

“This case has nothing to do with race,” Texas prosecutor Bill Wirskye said. “This case is not self- defense.”

“Unjustified provoked murder — That’s why we’re here this morning,” he added.

Civil rights organization Next Generation Action Network said in a post on X on Wednesday that it was “outraged” that none of the jurors selected are Black.

“The prosecution used its final strikes to remove the remaining qualified Black jurors from the jury pool, raising serious concerns about fairness and equal justice,” the group said. “We respect the court, but we will not remain silent.”

Jeff Metcalf said his son was killed when another student armed with a knife got upset after being told he was in the wrong spot. Austin Metcalf was stabbed in the chest and died in his twin brother’s arms, his dad said. His twin brother, Hunter Metcalf, was not the courthouse on Thursday.

“They were twins, identical twins, and his brother was holding on to him, trying to make it stop bleeding, and he died in his brother’s arms,” he said at the time. “I rushed up there and I saw him on the gurney and I could tell — they said he wasn’t breathing. I could see all the blood, and I saw where the wound was, and I was very concerned, so I had to find his brother, and we rushed to the hospital. And we prayed, and it’s God’s plan, I don’t understand it, but they weren’t able to save him. This is murder.”

Austin Metcalf had a 4.0 GPA, was MVP of the football team and was headed for college, according to his father.

“He was on the right track,” Jeff Metcalf said. “He was loved by many. He was a leader.”

In June 2025, Anthony was charged with first-degree murder.

“We know this case has struck a deep nerve — here in Collin County and beyond,” Collin County District Attorney Greg Willis said at the time. “That’s understandable. When something like this happens at a school event, it shakes people to the core.”

On Thursday, prosecutors said Anthony “lied when he got caught.”

“He tossed the knife immediately after. Why toss the knife?Someone who’s scared doesn’t do that,” said Wirskye.

Mike Howard, Anthony’s attorney, said that his client was protecting himself.

“We expect that when the full story is heard, the prosecution will not be able to rule out that Karmelo Anthony may have acted in self defense,” he said.

“We understand that this case has sparked strong reactions.,” Howard added. “Please remember that there are real human beings, kids, on both sides of this case.”

In Texas, 17-year-olds are considered adults. If Anthony is found guilty, he could face 5 years to life in Texas state prison.

Anthony posted a $250,000 bond for his release and has since been under house arrest. He was permitted to graduate high school and finished with a 3.7 GPA, nonprofit NGAN Next told NBC Dallas-Fort Worth.

“We are proud to share that Karmelo Anthony will graduate and receive his high school diploma, and that his academic achievements will not be disrupted,” the nonprofit told NBC Dallas-Fort Worth at the time.

Anthony was not allowed to participate in any senior graduation activities, NGAN told NBC Dallas-Fort Worth.

Representatives of the teenager have created a crowdfunding page — which has now raised more nearly $1.4 million — to help Anthony pay for legal fees and moving costs.
