The murder trial of Karmelo Anthony has gripped the nation, with video footage playing a central role in what prosecutors are calling a deliberate, unprovoked killing — and what the defense argues was a split-second act of self-defense. As closing arguments begin on June 9, 2026, here is a complete breakdown of all the video evidence presented to the jury.
Background: The Fatal Stabbing at Kuykendall Stadium
According to CBS News, on April 2, 2025, at approximately 10 a.m., officers from the Frisco Police Department responded to reports of a stabbing during a regional high school track meet at Kuykendall Stadium in Frisco, Texas. Two students — Karmelo Anthony, then 17, of Centennial High School, and Austin Metcalf, 17, of rival Memorial High School — became involved in a confrontation under a reserved team tent. Witnesses told police that Anthony sat uninvited in the bleachers beneath the Memorial High School tent, leading to a heated exchange before Metcalf was fatally stabbed in the chest.
As per NBC News, Anthony admitted to the stabbing upon his arrest but claimed it was an act of self-defense. He was later indicted for first-degree murder by a Collin County grand jury in June 2025. The trial formally began on June 1, 2026, with jury selection, and opening statements and testimony commenced on June 4, 2026.
The Surveillance Video: A Grainy But Crucial Piece of Evidence
Five Camera Angles From Frisco ISD
According to Fox News, Frisco ISD provided investigators with video from five separate camera angles around Kuykendall Stadium. The footage was reviewed and analyzed by forensic video expert Mark Porter, who was called as the prosecution’s very first witness.
As per Fox 4 Dallas, Porter walked jurors through video captured from multiple cameras positioned around the stadium. Jurors were shown grainy surveillance footage from a camera positioned across the field. While software allowed investigators to zoom in on portions of the video, the image quality deteriorated significantly as the footage was enlarged.
The Four-Minute Confrontation Under the Tent
According to TMZ, prosecutors contended that Karmelo Anthony fought with Austin Metcalf for approximately four minutes under the tent at the 2025 track meet before fatally stabbing him. Jurors were shown footage that appears to show one person shoving another person under the tent.
As per the prosecution’s presentation, the footage showed Anthony entering the team tent from behind before a series of rapid movements occurred moments later. Prosecutors maintained they could identify Anthony and Metcalf in the video — even though faces were not clearly visible — and said the footage showed one person running from the tent toward the exit after the altercation.
Defense Challenges the Footage’s Reliability
According to TMZ, during cross-examination, defense attorney Toby Shook challenged forensic analyst Mark Porter about the limitations of the surveillance footage. Porter acknowledged that the video, made up of a series of still images captured from a distance, could not pick up on mouth or head movements. When Shook asked, “You really can’t tell what people are doing under the tent, can you?” — Porter agreed.
The Arrest Bodycam Video: “I’m Not Alleged. I Did It.”
Officer Eduardo Cortez’s Bodycam
According to NBC News, before the lunch break on June 5, state prosecutor Bill Wirskye showed jurors a four-minute video of Anthony’s arrest, part of which was captured on the body camera of Officer Eduardo Cortez, a school resource officer with the Frisco Police Department. In the footage, Anthony is seen holding his hands above his head while Cortez radioed that he had located the suspect.
As per Court TV, the bodycam footage contained what may be the most striking words of the trial — Anthony was recorded saying, “He put his hands on me. I told him not to.” Separately, as per NBC News, Officer Cortez testified that Anthony told him: “I’m not alleged. I did it.”
Anthony’s Reaction to the Footage
According to The Gateway Pundit, citing the New York Post, Anthony visibly reacted during the playing of some of the more disturbing footage from the incident, appearing to “squirm” and showing signs of being unsettled. However, as per CBS News live trial updates, Anthony also watched some of the video evidence intently alongside the jury.
The Bodycam Footage of Austin Metcalf’s Final Moments
Paramedics Administering CPR
According to TMZ, prosecutors played bodycam footage in court that showed paramedics giving Austin Metcalf CPR after he was stabbed. The footage showed Metcalf unresponsive on the ground, still in his athletic wear, as emergency responders worked to save his life.
As per CBS News, the prosecution also played a chaotic 911 call featuring a coach administering CPR, capping the first day of testimony with deeply emotional material. Audible sobbing came from the gallery as the video played, and Metcalf’s family kept their heads bowed.
A Harrowing Scene for the Family
According to TMZ, Austin Metcalf’s mother and father were wrapped in the arms of family members as they broke down in tears while the bodycam footage played. As per CBS News live trial updates, Metcalf’s twin brother Hunter could be heard in the footage yelling to an officer, “My brother, my best friend — hurry up. He’s very messed up.” A CPR machine could be heard repeating its prompts in the background as paramedics worked frantically.
Witness Testimony on What the Videos Could Not Show
Eyewitnesses Describe the Confrontation
According to NBC News, multiple witnesses from Memorial High School testified that Anthony had sat uninvited under the tent reserved for their school. While witnesses confirmed that Metcalf pushed Anthony at one point, they maintained that Anthony was the primary instigator — having told Metcalf, “Touch me, see what happens,” according to prosecutors as cited by TMZ.
As per CBS News, one student witness told the jury that Anthony pulled a knife from his backpack and stabbed Metcalf in the chest. The witness added that he and other students initially thought the knife was a “bluff” and did not expect Anthony to actually use it.
A Coach’s Horrifying Discovery
According to Primetimer, Memorial High School coach Rob Starr testified about finding Metcalf on the ground. “I come over there… and my memory is kind of shaky… but what I do see is Austin on the ground and his face is purple… and he has a hole in his chest,” Starr said.
The Defense’s Counter-Narrative
Fear and Chaos, Not Murder
According to Oxygen.com, defense attorney Mike Howard told the jury in his opening statement that Anthony acted out of “fear and chaos.” As per NBC News, Howard argued: “After Karmelo defended himself with that knife, he ran. He didn’t stab again. He dropped the knife. He didn’t stab anyone else.”
According to Fox News, under Texas law, self-defense is considered a “confession and avoidance” defense — the defendant admits to the conduct but argues it was legally justified. However, prosecutors countered that a person cannot provoke the harm and then retreat behind self-defense.
Directed Verdict Attempt
As per Courthouse News Service, after the prosecution rested its case, defense attorneys immediately moved for a directed verdict, arguing that the state had failed to prove the elements of first-degree murder. The judge did not grant the motion, and the defense proceeded to present its own case.
Medical Evidence Presented Alongside the Video
According to Fox 7 as cited by Oxygen.com, Collin County Chief Medical Examiner Dr. Elizabeth Ventura testified that Metcalf was stabbed through the heart. She described the wound as approximately two and a half inches in length and stated that it was not survivable. As per CBS Texas, the judge warned the courtroom that her testimony would be graphic, prompting Metcalf’s family to leave the room. Prosecutor Bill Wirskye showed the jury four autopsy photos, with some jurors reportedly becoming emotional.
Where the Trial Stands: June 9, 2026
According to Biography.com, as of June 8, 2026, both the prosecution and defense have rested their cases. The prosecution called 21 witnesses over the course of the trial. The defense rested on Monday, June 8, after presenting its arguments.
As per Fox 26 Houston, closing arguments are expected to begin on Tuesday, June 9, 2026, after which the case will be handed to the jury. The judge has ordered that the jury be sequestered. According to NBC News, Anthony faces a murder charge that carries a sentence ranging from five years to life in prison if convicted. Although Anthony was 17 at the time of the stabbing, Texas law considers 17-year-olds to be adults for criminal prosecution purposes.
As per Fox 4 Dallas, if convicted of murder, Anthony faces a maximum sentence of five to 99 years in prison.
