A Collin County jury sentenced 19-year-old Karmelo Anthony to 35 years in prison for the murder of 17-year-old Austin Metcalf. The sentencing follows the April 2, 2025, stabbing death of Metcalf during a Frisco ISD track meet at Kuykendall Stadium.
How was the sentence reached?
Jurors reached the 35-year decision after two and a half hours of deliberation. Both the prosecution and the defense waived their right to opening statements during the sentencing phase.

The defense called only one witness, Anthony’s mother Kayla Hayes. Hayes testified to her son’s remorse, stating, “Yes, he’s very sorry for what he did.”
What was the defense’s legal strategy?
The defense argued that the stabbing resulted from “sudden passion,” claiming Anthony reacted in terror without time for calm reflection. They urged jurors to consider if the defendant acted during a split-second surge of emotion.
If the jury had accepted the sudden passion claim, the conviction would have been reduced to a second-degree felony. A second-degree felony carries a possible sentence of 2 to 20 years.
“He’s my oldest, he’s my firstborn,” Hayes said during her testimony. “He will always be my baby. I love him very much.”
What were the circumstances of the incident?
According to prosecutors, the dispute began near a team tent area at Kuykendall Stadium. Authorities stated that the two teenagers attended different schools and had no prior connection to one another.
Prosecutors alleged that Anthony deliberately stabbed Metcalf once in the chest during a confrontation. Metcalf was rushed to a hospital, where he later died from his injuries.
What could happen next?
With the 35-year sentence handed down, Anthony will likely begin serving his term in prison. The legal outcome could potentially be subject to the appeals process.
