Never-before-heard details from the Karmelo Anthony murder trial: The Daily Mail reporter with a front row seat reveals all in The Trial USA podcast

Published: 18:01, 17 June 2026 | Updated: 18:02, 17 June 2026 Two Texas teenagers. A fatal stabbing at a high school track meet. A murder conviction that sparked outrage, threats and split America in two. Karmelo Anthony was convicted last week of murdering Austin Metcalf after a confrontation at an April 2025 track meet involving rival high schools from an affluent Dallas suburb. Jurors heard how Anthony plunged a folding knife into Metcalf’s chest after being asked to leave a rival team’s tent during a rain delay. Anthony, who was 17 at the time, claimed self-defense. The jury rejected that argument and he was sentenced to 35 years in prison. Outside court, the case became a firestorm. Now, The Trial USA takes listeners inside the courtroom. Daily Mail Texas Bureau Chief Mary Anne Martinez, who covered the trial and faced threats over her reporting, reveals what jurors really heard, what the public got wrong and how one teen murder case became a national flashpoint.
