No cameras were allowed in the courtroom during the trial, making the newly released evidence the first public view of key recordings and images presented to the jury.

According to investigators, the confrontation began during a Frisco track meet when Anthony, a Centennial High School student, was sitting under Memorial High School’s team tent and Metcalf told him to leave.
Video Footage
Surveillance video shown to jurors captured a brief burst of activity under the Memorial High School tent. Jurors also viewed video highlighting Anthony running away from the scene.
Body camera footage from responding officers documented Anthony’s arrest.
During the encounter, Anthony can be heard saying, “I was just protecting myself.”
Later in the footage, Anthony said, “I know how it goes. I’m not alleged. I did it.”
Anthony can also be heard saying, “He put his hands on me. I told him not to, he put his hands on me.”
911 Calls
The evidence presented to jurors included multiple 911 calls made after the stabbing.
In one call, a caller told a dispatcher, “I need paramedics at Kuykendall Stadium right away.”
When asked what was happening, the caller responded, “I have an athlete that was stabbed.”
Another caller told a dispatcher, “My friend’s bleeding everywhere.”
Court records also included transcripts detailing efforts to save Metcalf’s life.
A caller reported, “We’re doing compressions and giving him mouth-to-mouth.”
Later, another caller can be heard saying, “Fight through. Fight through, Austin. Come on. Come on. Come on, Austin.”
Despite those efforts, family members said the 17-year-old died in his twin brother’s arms.
