FRISCO, Texas — One student died and another was arrested on a murder charge after a stabbing at a Frisco high school track meet Wednesday morning, police and family members confirmed to WFAA.

The stabbing happened around 10 a.m. at the University Interscholastic League’s (UIL) District 11-5A championship track meet, which was being held at the Frisco Independent School District’s Kuykendall Stadium.

The victim who died was 17-year-old Austin Metcalf. Family members told WFAA that he was a student athlete at Frisco’s Memorial High School. His twin brother Hunter, described him as a peacemaker and was loved by all his friends.

Meghan Metcalf, Austin’s mother, said she rushed to the hospital as soon as Hunter called her. 

“My son is not here anymore, and I don’t understand it,” she grieved. “He was the most amazing kid. So smart. He had college football guys looking at him to play in college. His goal was to play in college.”

Police said officers had responded around 10 a.m. to an altercation between two students. One of the students was stabbed by the other, according to police. Hunter Metclaf told WFAA that he was there when Austin was stabbed and tried to save his life by stopping the blood.

“I tried to whip around as fast as I could,” Hunter said with tears in his eyes. “I looked at my brother and I’m not going to talk about the rest. I tried to help him.” 

Hunter said he held his brother until first responders started attempting resuscitation.

Frisco police said CPR was performed on the victim, and blood was administered, but Metcalf later died.

“[Austin] did everything for our family,” said Hunter. “As a linebacker, he was a stud, and I always tried to fill those shoes and play with him. I had a blast my whole life playing sports with him.” 

Although Austin was only four minutes older than Hunter, he said, “I always looked up to him. He was a big brother even though we’re the same age.”

Meghan added, “We just want to make sure that everybody knows how much Austin is still going to be in our lives as far as our memories and our hearts forever. It’s going to eb really hard.”

The suspect, identified by police as Karmelo Anthony, a 17-year-old student at Frisco Centennial High School, was taken into custody on a murder charge. His bond has not been set yet.

Anthony played football in the secondary for Centennial and indicated on social media pages that he’d been offered scholarships to play football for several smaller schools. 

More details about what led to the stabbing have not been released.

Frisco school officials had said in an email that an “emergency incident” involving two Frisco ISD students forced the meet to be suspended. The stadium was “immediately secured” and students were sent back to their home campuses, according to officials.

UIL said in a statement that it’s “deeply saddened” by the incident and is working to provide assistance. 

“UIL is deeply saddened by the tragic incident that took place at the District 11-5A track meet on April 2 at Frisco ISD’s Kuykendall Stadium. UIL staff is in communication with district officials to provide support and assistance during this time,” the statement said. “Our thoughts go out to those impacted.”

Frisco school officials sent information about the incident in an email to parents and students of Memorial, Frisco, Centennial, Emerson, Heritage and Independence, Lebanon Trail and Liberty high schools.

A prayer vigil will be held Wednesday evening at Hope Fellowship Church in Frisco, where Austin would attend youth group sessions.
