A teenager who fatally stabbed a competitor at a Texas high school track meet was upset immediately after the confrontation and said he had warned the victim “not to touch me,” one of the last trial witnesses testified Monday.

Karmelo Anthony, now 19, is charged with murder in the death of Austin Metcalf, 17, at a school stadium in Frisco, a Dallas suburb, in April 2025.

After a midday break that lasted three hours, the prosecutor and defense lawyers said they had no more evidence to offer on the fourth day of trial. Anthony did not testify in his own defense, and closing arguments were set for Tuesday.

Prosecutors say the stabbing of Metcalf was an unjustified attack related to a dispute over whether Anthony could be under the tent of Metcalf’s team during a rainy track meet. Defense attorneys insist Anthony felt threatened and believed he needed to defend himself when physical contact was made.
