The sickening Karmelo Anthony crime scene photo that made jurors gasp in horror... a hideous detail about his knife... and every shocking moment of murder trial that guaranteed his 35-year sentence

By MARYANN MARTINEZ, US TEXAS BUREAU CHIEF Published: 23:34, 10 June 2026 | Updated: 23:52, 10 June 2026 It was a case that divided Texas and beyond, pored over by pundits for months and leaving many asking what justice looked like for a crime that quickly became a racial flashpoint. Yet on Tuesday, it took a Collin County jury in Dallas' suburbs just under three hours to convict 19-year-old Karmelo Anthony of murdering Austin Metcalf, 17, at a high school track meet last year. Anthony, who was also 17 at the time, stabbed Metcalf after a confrontation in a school tent – that much was never disputed, Anthony admitted to police he killed Metcalf minutes afterwards. The case ultimately hinged on whether Anthony was acting in self-defense, a theory the jury rejected resolutely, along with two lesser charges of manslaughter and sudden passion. The same 12-member panel (comprised of white, Asian, Hispanic and Indian jurors – but crucially no black jurors, something Anthony's defenders say was an injustice) also sentenced him to 35 years in prison. Despite all the outside attention on the case, jurors could only make their decision on evidence presented in court. From the Daily Mail's vantage in the courthouse jurors had the biggest reaction to several highly visual pieces of evidence, including a photo of Metcalf's punctured heart, printed out and blown up to poster size. The medical examiner testified that the knife penetrated deep enough to pierce bone and the heart itself.

Anthony says he stabbed Metcalf in self defense after a clash over seats in the bleachers  The prosecutor held the image and walked up to the jury to show it directly, so no one else in the courtroom could see. One juror, an Asian woman, gasped and covered her mouth in shock. During opening statements, defense attorney Mike Howard claimed Anthony had been ganged up on and feared for his life. However, surveillance video of the April 2, 2025, stabbing, shown in court and reviewed by the Daily Mail prior to trial, became central to the jury's rejection of that claim. The footage, while poor in quality and recorded from across the football field, shows students sitting under the Memorial High School team tent during a rain delay. There is no fight or large-scale brawl. There are no students surrounding or ganging up on anyone. Instead, it shows a one-on-one confrontation between two people.  Texas self-defense law generally requires a reasonable fear of serious bodily injury or death – a threshold the state argued the video did not support. Nearly a dozen students from several high schools gave testimony that students from other schools were not allowed under their team's tent. All agreed that Anthony, a student at Centennial, was asked to leave the Memorial High School tent more than ten times. 'It wasn't just Austin,' a teenager testified. 'People, including myself, were saying for him to leave.' However, Austin took the lead in asking Anthony to leave the team tent after his coach had asked him to take on a leadership role during the track meet.  Hours after his conviction for murder in Collin County, Texas, a new jail booking photo of Karmelo Anthony was made public, showing the 19-year-old as an inmate Victim Austin Metcalf, 17, died from a stab wound to the chest. Court testimony reveals his coach had asked him to help run the track meet and step up by 'being a leader' the day he died All the witnesses agreed Metcalf was unarmed and none described anything approaching a deadly threat to Anthony. None of them knew Anthony was armed - even when he put his hands in his book bag and said, 'Touch me and find out.' Several of the kids called his bluff, according to the testimonies, with Metcalf apparently saying: 'We're in Frisco. You don't have anything.' Frisco, known for its low crime rate, good schools and high incomes, is one of the most desirable communities for families in the Dallas-Fort Worth metroplex. Defense Attorney Mike Howard told jurors the Louisiana native had relocated from Baton Rouge with his family during his freshman year of high school, seeking a better life in the Lone Star State. As the verbal back-and-forth escalated, Metcalf stood up from the bleachers and walked over to Anthony, who was still seated. As Metcalf moved in to push him, Anthony pulled a knife from his backpack and plunged it into Metcalf's chest, striking his heart. In another pivotal moment of the trial, jurors were shown police body-worn camera footage capturing Anthony's confession to the arresting officer moments after the stabbing. Video of the violent confrontation reviewed by the Daily Mail shows coaches carrying a gravely wounded Metcalf down the stairs of the bleachers so he could be treated The video of the stabbing, reviewed by the Daily Mail, was captured from a camera next to the press box on the opposite side of the field Prosecutors tell Daily Mail that Karmelo Anthony used an Ozark Trail folding knife sold at Walmart for $13.36 in the killing of Austin Metcalf Frisco Police Officer Eduardo Cortez, who detained Anthony at David Kuykendall Stadium, told the court he was not questioning him and was acting solely to detain the suspect. He radioed other officers, stating: 'I got the alleged suspect in handcuff detained.' According to the footage, Anthony then said, 'I'm not alleged, I did it.' 'He put his hands on me. I told him not to,' Anthony added while sobbing. Other footage showed the aftermath of the stabbing. In one clip, the officer who recovered the weapon is seen sprinting across the field toward the bleachers where a wounded Metcalf is receiving first aid. As the officer nears the scene, Metcalf's twin brother, Hunter, is hysterical and being restrained by a coach. Hunter can be heard screaming: 'Oh my God. He's my best friend. He's my brother.' The officer reaches the bleachers where Metcalf is lying at the bottom, his shirt pulled up as coaches and medical staff attempt CPR. His 6ft1in, 213lb frame lays motionless as responders tried to save his life. The officer continues up the steps until he finds the knife Anthony had pulled from his backpack – an Ozark Trail folding knife with a black blade and grey handle. The weapon, sold at Walmart for $13, should not have been at the stadium, as Frisco school district policy prohibits weapons on school property or at events. Investigators said they could see 'bone and blood' still on the blade when police arrived, although some had been washed away by rain. Jurors also saw photographs of the bloody knife and the weapon itself, sealed in an evidence bag.

Anthony's legal team, led by lawyers Mike Howard and Toby Shooks, called six witnesses. One was Anthony's former track coach, who said that students from multiple schools often ended up in each other's tents. He was the only person to say this, and it is widely know in the track world that tents are like locker rooms - only members of the team are allowed to be inside. Another was a police officer who interviewed witnesses but offered no evidence supporting self-defense.  Four student witnesses also testified, but one may have done more harm than good. One student walked back a previous statement to Frisco police that Anthony had been 'surrounded,' clarifying he saw students sitting around Anthony rather than ganging up on him. 'I don't want to phrase it as "surrounding,"' the student said in court. There had been speculation in the final days of the trial that Anthony might take the stand, but he never did. For many, no amount of evidence will change baseless opinions. Many on social media have falsely claimed that Anthony skipped school and was not supposed to be at the track meet. He was, in fact, scheduled to take part in several events and even rode the bus to school.  Meanwhile, others have stated that Metcalf and Anthony knew each other before the stabbing, while there is no evidence of that.  The boys crossed paths at the track meet for the first time in a day that would change both of their lives forever.  No comments have so far been submitted.
