Finally, the entirety of Karmelo Anthony’s barbaric and cruel insults directed at the victim before murdering her have been revealed; all of his testimony has been exposed in court…

Opening statements began Thursday morning in the murder trial of a Frisco ISD student accused of fatally stabbing another student at a track meet.

Karmelo Anthony, 19, faces a murder charge in the death of 17-year-old Austin Metcalf. Police said Anthony and Metcalf got into an argument over seating in the stadium stands on April 2, 2025, which escalated when Anthony stabbed Metcalf in the chest with a pocketknife.

The trial is expected to last approximately two weeks. If convicted, Anthony faces a maximum sentence of five to 99 years or life in prison.

Live Updates: Karmelo Anthony Trial

6 p.m. Court adjourns

The trial is done for the day. Testimony is expected to resume at 9 a.m. CST on Friday morning.

Todd Shapiro, an attorney not involved with the case, tells FOX 4’s Amelia Jones the prosecution and the bloody jacket left a strong impression after the first day.

“I think it being at the end of the day really left a very strong impression on the jury’s mind as they go home tonight. It’s a long trial, there’s going to be a lot of twists and turns, but today if you were to ask me, I would say the prosecution scored some pretty big points.”

I thought it was incredibly powerful, one of the most powerful moments I can recall in trials that I’ve had in hearing something like that and listening to the reaction of the people around the young man who is losing his life right in front of their eyes.”

5:45 p.m. Cross-examination

Under cross-examination, defense attorneys focused on conversations between athletes from other schools, and whether that’s allowed.

The defense asked Rebmann if he knew that Centennial High School, where Anthony was a student, did not have a tent up. Rebmann responded that he did not.

Anthony’s attorney also asked the coach where another student warming up might want to seek shelter. Rebmann said he didn’t know.

“It makes sense though,” the defense said.

“I guess so,” Rebmann admitted.

5:30 p.m. 911 call and more videos

There were a lot of tears from those in the courtroom as the 911 call was played for the jury.

In the 911, there are screams and sounds of a chaotic scene in the background. Rebmann can also be heard in the background repeatedly saying, “Stay with me, Austin. Stay with me, Austin.” Then again, “Come on, Austin. Come on, Austin.”

The jury was shown photos of the proximity of the Liberty and Memorial tents, Metcalf’s coloring, and the jacket that Redmon used to put pressure on his wound.

DA Wirskye also pulled out the physical jacket that is still stained with Metcalf’s blood.

Jurors were shown another video from the west side of the stadium that shows the Liberty High School tent. It starts off calm with students walking around and then shows students running away from the Memorial High School tent. Coach Rebmann can be seen running towards the Memorial ten.

Another video from the east side of the stadium shows Rebmann taking off his jacket and putting it on top of Metcalf as he’s lying on the ground.

5 p.m. More coaches testify

Joshua Rebmann, a football defensive coordinator at Liberty High School, took the stand. He was one of the coaches at the track meet.

Rebmann was standing about 20 feet from the Memorial tent under the Liberty team’s tent. He was speaking with another coach when heard the commotion of students running down the bleachers.

He testified that he saw Metcalf up against a fence holding his abdomen. He heard someone (possibly Metcalf’s brother, Hunter) say he was stabbed.

Rebmann said he used his jacket to put pressure on his wound. He described calling for other coaches to call 911 He is a military veteran and has seen combat.

Rebmann shared that once he realized blood was staying in his abdomen, Metcalf’s color started turning. His eyes rolled to the back of his head. Rebmann said he realized there was no pulse and that he needed to do CPR.

One coach was doing chest compressions, another was doing mouth-to-mouth. Rebmann described Metcalf “gasping for air.”

4:45 p.m. Afternoon break

The trial took a 20-minute afternoon break.

Earlier in the day, FOX 4’s Alex Boyer talked to Jeff Metcalf, the victim’s father. He called this a “tough day for everyone.”

He also talked to a trial attorney who was in the courtroom as an observer.

“The state opened first. I think Bill Wirskye is a tremendous trial lawyer. He really captivates an audience. He’s a really tall guy, and he has a very commanding voice and really laid out logically where the road map of the state’s case was going to go. Once he was done with his opening, then the defense got to do their opening. And the thing that stood out to me the most about the defense’s open is that they never mentioned how or why the knife was in Anthony‘s bag at the track meet. I imagine that it was purposely that they chose not to bring that topic up,” he said.

When asked about the video, Shapiro said it didn’t give a clear picture of what was taking place.

“You can’t see any faces. You can’t see the actual act take place. You can see a little scuffle and then you see everybody scatter. So it doesn’t necessarily prove anything. I believe it’s laying the necessary ground work for what’s to come,” he said.

3:30 p.m. Coaches testify

Memorial High School coach Robert Starr took the stand next. He was Metcalf’s track coach. He explained to jurors that a tent at a track competition typically “marks your spot.” He said it’s similar to a team bench for other sports.

“You just don’t go into someone else’s tent uninvited,” Starr testified.

He got choked up describing when he saw Metcalf injured.

Prosecutors also called Memorial High School athletic trainer Tiffany Whiteaker and Heritage High School football coach and interim athletic coordinator Vincent Hooper to the stand.

2 p.m. Cross-examination

Defense attorney Toby Shook cross-examined the video analyst.

1 p.m. Video testimony

Following the lunch break, the same witness, video analyst Mark Porter returned to the stand to talk about how he used a magnification filter to zero in on the people of interest and a spotlight filter with increased brightness on it.

He said only about 15 minutes passed between the time Metcalf entered the stadium and Anthony was arrested.

11:45 a.m. Lunch break

Court was dismissed for a 45-minute lunch break.

Outside the courthouse, protestors on both sides of the case seemed to be getting rowdy. A Collin County constable gave them a warning.

One of the protesters is Jake Lang, an activist who was arrested earlier this week for criminal trespassing.
