‘I’m Not Alleged, I Did It’: Crying Karmelo Anthony Confesses on Newly Released Bodycam Video After High School Track Murder

FRISCO, Texas — Newly released police body camera footage has captured the chilling and emotional moments immediately following the arrest of 19-year-old Karmelo Anthony. The former high school star athlete was captured on camera crying and explicitly confessing to the fatal stabbing of 17-year-old Austin Metcalf, bluntly telling an arresting officer, “I’m not alleged. I did it.”

The footage, made public by a Collin County court judge on Friday, June 19, 2026, offers a raw, unfiltered look at the immediate aftermath of a tragedy that shook North Texas and sparked national conversations surrounding school safety, race, and self-defense laws. The release comes just weeks after a jury rejected Anthony’s self-defense claims, convicting him of first-degree murder and sentencing him to 35 years in prison.

The Arrest and the Unfiltered Confession

The video, recorded by an assisting officer’s bodycam at David Kuykendall Stadium in Frisco, begins with law enforcement tracking down Anthony shortly after the stabbing on April 2, 2025. Anthony, a captain of the Centennial High School football and track teams who had no prior criminal record, is seen being taken into custody right on the high school running track.

As an officer radios into dispatch to report that they have the “alleged suspect” in custody, Anthony immediately interrupts him.

“I’m not alleged. I did it,” Anthony can be heard saying clearly on the recording, his hands visibly stained with blood.

As officers search his pockets and escort him toward a police cruiser, Anthony becomes increasingly emotional, weeping as he attempts to justify his actions. He repeatedly tells officers that Metcalf had initiated physical contact.

“He put his hands on me. I told him not to. He put his hands on me,” Anthony claimed through tears. He is also heard frantically asking officers if Metcalf was going to survive the injury.

Inside the Track Meet Tragedy: What Led to the Fatal Stabbing

The tragedy unfolded during a District 11 track and field championship meet. When heavy thunderstorms and torrential downpours delayed the events, students sought shelter. While most schools had designated tents, Anthony’s team did not. After being asked to leave a baseball dugout by a coach, Anthony sought refuge under a tent set up by Memorial High School—the rival school where Austin Metcalf was a junior linebacker.

According to court documents and witness testimony, an altercation ensued when Memorial students, including Austin’s twin brother, Hunter Metcalf, asked Anthony to leave their designated seating area. Witnesses estimated that Anthony was asked to leave up to 15 times over a two-minute span.

The situation escalated when Anthony allegedly placed his hand inside his backpack and warned the crowd, “Touch me and see what happens.”

According to police reports, one student taunted Anthony, saying, “You don’t have anything in that backpack. It’s Frisco.” Moments later, Austin Metcalf stood up and pushed Anthony in an attempt to eject him from the tent. In a swift reaction, Anthony pulled a 5-inch black folding Ozark Trail multi-tool knife from his bag and plunged it once into Metcalf’s chest.

Surveillance footage released alongside the bodycam video shows Metcalf grabbing his chest and running down the stadium bleachers to find help. Despite frantic chest compressions performed by an Army veteran and athletic trainers on the scene, the blade had pierced Metcalf’s heart. The Collin County Chief Medical Examiner later testified that the 2.5-inch-deep wound was completely “not survivable.” Metcalf was pronounced dead shortly after arriving at the hospital.

A Divisive Trial and a Swift Verdict

The trial, which concluded on June 9, 2026, became a highly divisive flashpoint. Because the presiding District Judge John Roach Jr. had placed a strict gag order on the case and barred cameras from the courtroom, the newly released trial exhibits—which include the bodycam footage, 911 calls, crime scene photos, and images of the blood-soaked murder weapon—mark the public’s first detailed look at the evidence presented to the jury.

During the trial, Collin County District Attorney Bill Wirskye argued that the killing was a “provoked, unjustified murder.” The prosecution contended that Anthony intentionally baited the victim into touching him so he could deploy a concealed weapon in a “sneak attack.”

Conversely, defense attorney Michael Howard argued that Anthony, who maintained a 3.7 GPA and worked two part-time jobs, acted out of a “split second of fear and chaos” when a large group of rival students began to gang up on him. The defense insisted it was a tragic case of self-defense.

Ultimately, the jury sided with the prosecution. After a multi-day trial featuring testimony from 21 witnesses, the jury took just three hours of deliberation to find Anthony guilty of first-degree murder.

The Aftermath and Sentence

Though Anthony was 17 at the time of the crime, he was tried as an adult under Texas law, exposing him to a maximum penalty of life in prison. The jury ultimately settled on a 35-year prison sentence. Under Texas sentencing guidelines for violent crimes, Anthony must serve at least half of his sentence—17.5 years—before he becomes eligible for parole.

The release of the bodycam video closes a dark chapter for the Frisco community, but the emotional scars remain deep. While the Metcalf family continues to mourn the sudden loss of a promising young athlete and brother, the family of Karmelo Anthony maintains that the situation was a catastrophic escalation of a minor dispute that should have never cost a life.

The haunting audio of Anthony crying in the back of the police car, declaring his own definitive guilt, stands as a grim reminder of how a few seconds of unchecked anger can permanently destroy the futures of two young men.
