Horrific moment Karmelo Anthony stabbed Austin Metcalf is shown in new surveillance footage
A newly released surveillance video has revealed the moments after Karmelo Anthony fatally stabbed Texas teen Austin Metcalf, showing the convicted killer running from the scene as panic erupted in the stands.
The footage, released by the Collin County District Court, captures students gathered beneath a yellow tent at Kuykendall Stadium in Frisco, Texas, during a rainy track meet on April 2, 2025. Metcalf, a student at Memorial High School, was with teammates when Anthony entered the tent.
According to witnesses, Anthony had been asked to leave the area but refused. Moments later, the confrontation escalated into violence, leaving Metcalf with a fatal stab wound to the chest.
Surveillance footage captures chaotic aftermath
The security video shows a group of student athletes sitting calmly beneath the tent before Anthony approached.
While the actual stabbing is only partially visible near the top of the frame, the footage shows a person suddenly collapsing onto the bleachers. The incident immediately sends students scrambling from their seats as confusion spreads through the crowd.
Seconds later, Anthony can be seen emerging from the rear of the tent before sprinting down the stands and out of the stadium. According to the report, he had used a 3.5-inch blade to stab Metcalf in the chest.
One unidentified person briefly chased the then 17-year-old, but quickly abandoned the pursuit as Anthony continued running from the scene.
Witnesses described confrontation before stabbing
Witnesses told investigators that Anthony, a student at Frisco Centennial High School, became confrontational after being asked to leave the Memorial High School team's tent.
A 15-year-old who was present during the incident testified that Anthony “tried to provoke us.”
According to the witness, Anthony responded to requests that he leave by saying: “F**k y’all. I’m not going to leave. Y’all are a bunch of p**sies. Y’all not going to do anything.”
The confrontation ended with Metcalf suffering the fatal wound that ultimately claimed his life.
911 audio reveals desperate rescue efforts
Disturbing audio from 911 calls made immediately after the stabbing was also released Friday, providing insight into the desperate attempts to save Metcalf.
“My friend’s bleeding everywhere,” one student told dispatchers.
As emergency responders were being contacted, a track coach performing CPR could be heard encouraging the injured teen.
“Fight through! Fight through! You’re doing good,” the coach said in the background of the call.
Anthony, now 19, was later convicted of murder. On June 9, he was sentenced to 35 years in prison for the killing of Metcalf.
