Image Of Murder Weapon In Karmelo Anthony Case Released For First Time

Collin County District Judge John Roach Jr. released on Saturday more than six gigabytes of trial evidence to the public in the case of State of Texas v. Karmelo Sincere Anthony. This release included the first public photographs of the murder weapon used in the April 2, 2025, stabbing death of 17-year-old Austin Metcalf at David Kuykendall Stadium in Frisco, Texas.

The weapon was an Ozark Trail 6-in-1 Multitool Knife with Light, Model 5335, a folding utility tool sold at Walmart for approximately $13. It featured a 3.5-inch serrated blade, a flashlight, and additional tools such as a glass breaker. The knife had a gray or silver textured handle and a dark or black blade.

Prosecutors described it during the trial as a 3½-inch weapon that was “not particularly a quality knife,” yet it proved lethal when deployed.

Photographs released by the court showed the folding knife on a surface consistent with bleachers or a similar location at the scene. One image depicted the knife with its blade partially extended.

Additional evidence photos included a blood-stained jacket associated with the victim and an uncensored close-up view of Metcalf’s approximately two-inch chest wound from the autopsy. Surveillance footage and body-camera recordings were also made public, showing Anthony after the incident.

The knife was recovered blood-stained from the stadium bleachers area by a Frisco Police Department school resource officer. It had been discarded by Anthony as he fled the scene.

Trial testimony indicated the knife could be opened with a quick single-flick motion. A police officer testified that carrying a knife of this approximate length (up to 5 inches) is lawful in Texas, although it violated school policy.

Anthony carried the multi-tool knife in his backpack on the day of the track meet. No trial evidence detailed a specific reason for bringing it to the event that day.

He was a student at Centennial High School attending the meet at Memorial High School’s stadium at the time of the killing. The knife remained in his possession inside the backpack until he removed it during the confrontation.

The incident took place on April 2, 2025, at David Kuykendall Stadium in Frisco, Texas, during a district-wide track meet affected by rain. Anthony, a student at Centennial High School, was under the Memorial High School team tent when members of that team, including Metcalf, confronted him and told him to leave.

Multiple witnesses testified that Anthony refused and made a number of statements such as, “touch me and see what happens” while reaching into his backpack and later, “punch me and see what happens.”

One witness testified that Metcalf responded to Anthony’s challenge by saying, to the effect of, “Dude, I’m not gonna fight you at a track meet.” Witnesses indicated Metcalf did not appear interested in escalating to a physical fight

After being told to leave upwards of 15 times, according to witnesses, Metcalf eventually lightly shoved Anthony. At that point, the killer reached into his backpack and produced a knife before fatally stabbing Anthony in the chest.

Anthony was ultimately sentenced to 35 years in prison after being convicted of murder.
