A teenage track meet turned into a homicide scene in seconds, and now a single distraught sentence — “I told him not to touch me” — sits at the center of a fight over what counts as self-defense in America.

- The defense says he was cornered, seated, and reacted in a split second of fear and chaos.[1][4][6]
- Witnesses describe Anthony as both “the aggressor” and “distraught,” leaving jurors to decide what those few seconds really mean.[2][4][5]
From Rain Delay To Murder Charge In Seconds
Thousands of parents have sat through a rainy school sports day, bored and cold, never once thinking it could end in a murder trial. On April 2, 2025, at Kuykendall Stadium in Frisco, Texas, a district track meet stalled for thunderstorms.[1][4][5] Under one crowded team tent, 17-year-old Austin Metcalf from Memorial High School told 17-year-old Centennial student Karmelo Anthony he did not belong there and should leave.[4][5] Minutes later, Metcalf lay dying from a single stab wound to the chest.[4][5]
Police and witnesses say the two teens had never met before that morning.[4][5] The conflict began over seating and shelter under a Memorial High School tent as rain poured down.[1][4][5] Witnesses testified that Anthony entered the Memorial tent, refused multiple requests to leave, and sat with his backpack on his lap while Memorial athletes grew more frustrated.[1][2][4][5] The entire chain of events, from words to fatal wound, unfolded in a matter of seconds, not minutes.[1][4][5]
The Prosecution’s Story: A Provoked, Unjustified Murder
Collin County District Attorney Bill Wirskye tells jurors this was not a tragic misunderstanding but a “provoked unjustified murder.”[4][5][6] According to witnesses he called, Anthony stayed in the tent after repeated demands to move.[1][2][4][5] They say he goaded Metcalf with lines like “Touch me and see what happens” while keeping one hand buried in his backpack, suggesting a hidden weapon.[1][2][5][6] When Metcalf finally shoved his shoulders, Anthony stood and drove a folding knife into his chest.[1][2][4][5]
Witnesses describe a single, devastating stab that pierced Metcalf’s heart, leaving what one report called a wide, gaping wound.[5] Students and staff tried to save him with chest compressions before he was rushed to a hospital, where doctors could not bring him back.[5] Prosecutors point to Anthony’s concealed knife, brought to a school event, as proof he arrived with deadly capability in his pocket.[1][2][5] They argue he created the conflict, baited the contact, then launched a “sneak attack” and ran.[4][5][6]
The Defense’s Story: A Teen Cornered In Fear And Chaos
The defense flips the same moments on their head and leans on something most parents understand: how fast a crowd can turn on one kid. Defense attorney Mike Howard says Anthony sat the whole time, surrounded by about 20 Memorial students, as Metcalf and his twin brother stood over him.[1][4][6] He argues that Metcalf made first physical contact and that Anthony reacted “in a split second of fear and chaos” when the group seemed to turn hostile.[1][4][6]
Anthony told police after the stabbing, “He put his hands on me. I told him not to,” a line that fits a self-defense story as much as a confession.[2][5] One student witness testified he looked “distraught” afterward.[2] Police body camera footage captured Anthony saying, “I did it,” but also insisting he was protecting himself.[2][5] The defense leans on Texas self-defense law, which centers on whether a person reasonably feared serious harm, not whether they used a weapon that others lacked.[4][5][6] From that view, a lone teen seated under a hostile team’s tent may have felt trapped more than tough.
What “I Told Him Not To Touch Me” Really Fights Over
Almost every witness and reporter circles back to one phrase: “I told him not to touch me.”[2][5] Prosecutors use it to show Anthony planned to use the shove as his green light, since he dared Metcalf to make contact while hiding a knife.[1][2][5][6] The defense uses it to show he set a boundary, saw it crossed, and reacted in panic. The words do not change. The meaning does, depending on what you think came next and how much fear counts.
No, it's not true.

American conservative values usually line up this way: self-defense is a core right, but so is personal responsibility. A shove from an unarmed teen almost never justifies a knife to the heart, especially when the person with the knife helped start the fight by refusing to leave another team’s space.[1][2][4][5][6] At the same time, jurors must judge those seconds, not the headlines. They must weigh crowded bleachers, teen bravado, and a distraught kid saying “I did it” against the law’s demand for reasonable fear and proportional force.[2][4][5]
