Frisco track meet stabbing 

The backstory:

Karmelo Anthony, the teenager who fatally stabbed a fellow student during a high school track meet last year, was sentenced to 35 years in prison on Tuesday, June 9.

The 19-year-old was convicted for the April 2, 2025, murder of Austin Metcalf, 17, at a stadium in the Dallas suburb of Frisco.

Anthony and his lawyers have since appealed the conviction. Anthony was transported to the Texas Department of Criminal Justice, where he was then transported to his unit of assignment at the Pack Unit near Navasota.

Witnesses told investigators the confrontation began during a regional track meet at Kuykendall Stadium in Frisco. Anthony, a student at Centennial High School, was sitting under the Memorial High School team tent when Austin Metcalf, a Memorial High School student, reportedly told him to leave. Investigators said they found no evidence the two teenagers knew each other before the incident.

According to an arrest report, witnesses identified Anthony to a school resource officer shortly after the stabbing. The officer reported that Anthony repeatedly claimed he acted in self-defense.

The report states that after being taken into custody, Anthony told officers, "I was protecting myself" and "He put his hands on me." According to the report, Anthony also asked officers whether the victim would be okay and whether the incident could be considered self-defense.

Karmelo Anthony sentenced to 35 years in prison

A Collin County jury has sentenced Karmelo Anthony to 35 years in prison after finding him guilty of murdering 17-year-old Austin Metcalf at a 2025 Frisco track meet. FOX 4 reporters who were on site at the Collin County courthouse recap the emotional conviction and sentencing.

In the days following the stabbing, the case drew widespread attention on social media. Anthony continued to maintain that he acted in self-defense while being held in the Collin County Jail on a $1 million bond. A judge later reduced the bond to $250,000, citing Anthony's lack of a prior criminal record.

Days later, Anthony's family held a news conference and called for the public to allow the judicial process to proceed.

"I don't know why we are being targeted and discriminated against before a fair trial," Anthony's mother, Kayla Hayes, said at the time.

Public attention intensified when Metcalf's father attended the family's news conference. Police later escorted him from the event after organizers said he was not invited.
