A Texas judge on Saturday released more than six gigabytes of evidence from the murder case against Karmelo Sincere Anthony, including the first public photographs of the knife used in the fatal stabbing of 17-year-old Austin Metcalf.
Collin County District Judge John Roach Jr. authorized the public release of evidence from the case, which concluded with Anthony’s conviction and sentencing earlier this year.
The newly released materials included photographs of the weapon, surveillance footage, body-camera recordings and additional crime scene evidence.
According to court records, the knife was identified as an Ozark Trail 6-in-1 Multitool Knife with Light, Model 5335.
The folding multi-tool is sold at Walmart for approximately $13 and features a serrated blade, flashlight and additional utility tools.
Prosecutors described the knife during trial proceedings as a 3.5-inch weapon that was “not particularly a quality knife.”
Despite its low cost and basic design, prosecutors argued it proved deadly during the confrontation that led to Metcalf’s death.
Photographs released by the court showed the folding knife resting on a surface consistent with stadium bleachers.
One image appeared to show the blade partially extended.
Additional evidence included photographs of a blood-stained jacket associated with Metcalf and autopsy images documenting the fatal chest wound.
Authorities also released surveillance video and police body-camera footage connected to the investigation.
According to trial testimony, the knife was recovered by a Frisco Police Department school resource officer from the bleacher area after the stabbing.
Prosecutors said Anthony discarded the weapon while fleeing the scene.
Witnesses testified during trial that the knife could be opened with a quick flicking motion.
A police officer also testified that carrying a knife of that size is legal under Texas law, although possession violated school policy.
Evidence presented at trial showed Anthony carried the multi-tool in his backpack while attending a district-wide track meet on April 2, 2025.
The event was held at David Kuykendall Stadium in Frisco and involved students from multiple schools.
Anthony, a student at Centennial High School, was reportedly standing beneath the Memorial High School team tent when the confrontation began.
Multiple witnesses testified that students repeatedly asked Anthony to leave the area.
According to testimony, Anthony responded with statements including “touch me and see what happens” and “punch me and see what happens.”
Witnesses said Anthony reached into his backpack during the exchange.
One witness testified that Metcalf responded by indicating he was not interested in fighting, per Trending Politics.
According to testimony presented during the trial, Anthony was asked to leave the area more than a dozen times.
Witnesses stated that Metcalf eventually pushed Anthony during the confrontation.
Prosecutors argued that Anthony then removed the knife from his backpack and stabbed Metcalf in the chest.
Metcalf later died from the wound.
The newly released evidence provides the public with its first detailed look at the weapon and other materials introduced during the high-profile trial.
Anthony was convicted of murder and sentenced to 35 years in prison.
The evidence release comes as public interest in the case remains high following the conclusion of the trial and sentencing proceedings.
