A Texas judge on Saturday authorized the public release of more than six gigabytes of evidence from the murder case against Karmelo Sincere Anthony. The newly unveiled materials include the first public photographs of the knife identified as the weapon used in the fatal stabbing of 17-year-old Austin Metcalf. Collin County District Judge John Roach Jr. approved the release, following Anthony’s conviction and sentencing earlier this year.
"I am not alleged. I did it" — Karmelo Anthony, during arrest
The evidence trove encompasses photographs of the knife, surveillance footage, police body-camera recordings, and additional crime scene evidence. Among the most anticipated disclosures were images of the weapon, identified in court records as an Ozark Trail 6-in-1 Multitool Knife with Light, Model 5335. This folding multi-tool, commonly sold at Walmart for around $13, features a serrated blade, a flashlight, and other utility tools. Prosecutors, during the trial, characterized the knife as a 3.5-inch weapon, noting it was “not particularly a quality knife,” yet proved deadly.
The released photographs depict the folding knife resting on a surface that appeared consistent with stadium bleachers, with one image showing the blade partially extended. Other evidence included photographs of a blood-stained jacket associated with Metcalf and autopsy images detailing the fatal chest wound. Surveillance video and police body-camera footage from the investigation were also made public.
According to trial testimony, the incident occurred on April 2, 2025, during a district-wide track meet held at David Kuykendall Stadium in Frisco, involving students from multiple schools. Karmelo Anthony, a student at Centennial High School, was reportedly standing beneath the Memorial High School team tent when a confrontation began. Multiple witnesses testified that students repeatedly asked Anthony to leave the area. Testimony indicated Anthony responded with provocative statements such as “touch me and see what happens” and “punch me and see what happens.”
During the exchange, Anthony reportedly reached into his backpack. One witness testified that Metcalf indicated he was not interested in fighting. However, after being asked to leave the area more than a dozen times, Metcalf eventually pushed Anthony. Prosecutors contended that Anthony then retrieved the knife from his backpack and stabbed Metcalf in the chest, leading to Metcalf's death.
A Frisco Police Department school resource officer recovered the multi-tool from the bleacher area after the stabbing, with prosecutors asserting Anthony discarded the weapon while attempting to flee the scene. Witnesses during the trial testified that the knife could be opened with a quick flicking motion. A police officer also confirmed that carrying a knife of that size is legal under Texas law, though its possession violated school policy.
Bodycam footage released in connection with the case captured Karmelo Anthony admitting to the stabbing during his arrest, stating, "I am not alleged. I I did it." Anthony was subsequently convicted of murder and sentenced to 35 years in prison. The release of this comprehensive evidence comes as public interest in the case remains high, following the conclusion of the trial and sentencing proceedings.
