A Texas teen’s fatal stabbing at a school track meet is now playing out on bodycam and surveillance video, raising hard questions about self-defense, school safety, and how the justice system handles violent kids.

Story Snapshot

Newly released police body camera and stadium surveillance videos show the arrest and moments around the fatal stabbing of 17-year-old Austin Metcalf at a Frisco, Texas, track meet.
A Collin County jury watched this footage, heard witness testimony that Karmelo Anthony provoked the fight, and still had to weigh his claim of self-defense against the evidence.^[3]^[6]
The videos do not clearly show the exact stab wound, but they do capture Anthony fleeing, blood on his hand, and his emotional statements to officers.^[2]^[5]
The case exposes deeper problems: schools that cannot keep weapons off campus, media clips that shape the narrative before facts are in, and a justice system many parents feel has gone soft on crime.^[1]^[6]

What the Released Videos and Court Evidence Show

Police body camera video from the arrest and stadium surveillance footage were released by a Collin County judge after being used as evidence in The State of Texas vs. Karmelo Anthony.^[2] Local outlets report that jurors saw the arrest body camera video in court, along with still images and physical exhibits such as the knife recovered several rows up in the stadium bleachers.^[3]^[5] The surveillance camera, mounted near the press box, shows sudden movement under a team tent, followed by Anthony leaving and later the discovery of the weapon.^[2]

Reporters who watched the video describe it as grainy and distant, meaning you cannot clearly see the knife enter Metcalf’s chest.^[2] What the footage does show is a quick burst of activity at the tent, Anthony running from the scene, frantic efforts to save Metcalf, and officers tracking Anthony down shortly afterward.^[1]^[10] The arrest report notes that when an officer placed Anthony in the patrol car, he saw fresh blood on Anthony’s finger and spoke that detail out loud so it would be caught on camera.^[5]

Prosecutors Say Anthony Provoked the Fight and Carried a Hidden Knife

During trial, prosecutors built a picture of a teenager who brought a knife to a school event, refused repeated requests to move out from under another school’s tent, and then used deadly force the moment he was touched.^[6] One reported witness statement says Metcalf told Anthony he needed to move, saw Anthony reach into his bag, and heard him say, “Touch me and see what happens,” before Metcalf grabbed him and was stabbed once in the chest.^[16] Prosecutors described the killing as an unjustified, provoked attack, not a mutual fight gone wrong.^[9]

Several outlets say witnesses testified that Anthony “instigated the conflict” at the track meet and that he entered or remained under the tent when he knew he was not supposed to be there.^[3]^[6] The state also leaned on the fact that officers responded initially to a weapons call at the stadium, which shows they were not dealing with harmless horseplay but a serious threat.^[6] In the end, a Collin County jury accepted this view of the facts, finding Anthony guilty of murder and sentencing him to 35 years in prison.^[3]^[9]

The Defense: Self-Defense, Fear, and a Chaotic Teen Confrontation

Anthony’s lawyers argued that he was a scared teen in a tense situation, not a cold-blooded killer.^[12] In opening statements, they told jurors he made a split-second choice in fear and chaos after feeling cornered in the tent by a larger football player.^[12] At least one defense witness, a track teammate, reportedly testified that he saw Metcalf push Anthony first, which supports the claim that Anthony was reacting to an initial shove and did not throw the first physical blow.^[15]

Body camera audio from the arrest gave jurors their closest view of Anthony’s mindset in the moments after the stabbing.^[2] One local recap says he told officers, “He put his hands on me. I told him nothing. He put his hands on me,” directly claiming self-defense while still at the scene.^[2] Another commentary video notes that prosecutors timed this footage to play right after scenes of chaos at the stadium, using the contrast to push jurors away from sympathy and toward the picture of a teen who brought the knife and chose to use it.^[6]

Media Clips, School Safety Failures, and What This Means for Parents

This case also shows how short clips and social-media headlines can shape a story long before the full record is public.^[1] Commenters online pushed the idea that the body camera was a “smoking gun,” even though the arrest footage mostly shows the aftermath, Anthony’s emotional state, and small details like blood on his hand—not the act itself.^[2]^[5] NewsNation and other outlets described the surveillance video as key, yet also admitted it is distant and grainy, meaning the state’s account still depends heavily on witness stories and the arrest report.^[10]

NEW: Karmelo Anthony telling officer “I’m not alleged. I did it” right after stabbing Austin Metcalf

Newly released body camera footage shows the moment a second officer arrived on scene during the April 2025 track meet stabbing in Frisco.

For parents and taxpayers, the deeper concern is the same one they feel every time a “school incident” makes the news: how did a student get a knife into a district stadium in the first place, and why did adults not break this up before it turned deadly?^[2]^[6] The fact that this happened at a public school event, in the bleachers, under a tent, at a time when so many districts focus on pronouns and politics instead of discipline and security, only adds to that frustration.
