Austin Metcalf's harrowing final moments are laid bare in two shattering 911 calls placed just after he was stabbed by Karmelo Anthony at a Texas track meet.

The heartbreaking audio reveals how Metcalf's coaches tried desperately to keep him conscious with one begging him to 'fight through' before he succumbed to his wounds.

The 17-year-old was fatally knifed by Anthony, 19, during the athletics event in Frisco on April 2, 2025. 

In one emergency call, a friend of Metcalf's who identifies himself as Mason, is heard telling operators: 'My friend is bleeding everywhere!'

The 911 calls were played to jurors during Anthony's murder trial which ultimately saw him convicted and sentenced to 35 years in jail earlier this week.

The emotional audio was unsealed by a judge Friday along with a trove of other evidence, including security footage which showed Anthony attempting to flee the stands as Metcalf lay dying.

In another clip, Metcalf's coach Robert Thayer can be heard frantically begging for paramedics to get to David Kuykendall Stadium to help the stricken teen.

'We have an army veteran trying to keep compression on the wound,' Thayer tells a 911 dispatcher. 'He [Metcalf] is laying here, he's starting to go unconscious.'

As he continues to give details about Metcalf's condition, Liberty High School football coach Joshua Rebmann is heard repeatedly shouting: 'Stay with me Austin, stay with me.'

The operator then asks if they know any details about the assailant but Thayer says: 'We have no idea, everybody just took off afterwards. There's a lot of blood, he's not breathing.'

In the background Rebmann is heard shouting: 'Stay with me, you're alright. Come on.'

The dispatcher then attempts to coach Thayer through administering first aid to try and stop the bleeding.

The operator instructs him to press down on the wound firmly, warning it is likely to hurt Metcalf.

Thayer tells her that they are attempting CPR and giving him mouth to mouth before EMS arrives on the scene. Tragically their efforts were unsuccessful and Metcalf died in the arms of his twin brother who was also at the track meet.

Meanwhile in a separate call, Mason is heard telling the operator: 'My friend just got stabbed!' 

He then describes Anthony as 'wearing a grey essential hoodie, he's black, he's standing on the track right now.'

The boy is unsure of what his friend was stabbed with but pleads for help: 'I don't know, my friend's bleeding everywhere!'

He believed at the time that coaches had Anthony subdued.

The audio was released alongside a massive tranche of videos and photos from the case by a federal judge, including gruesome photographs and enhanced security footage of the moments before and after the stabbing.

A video shows movement under the Memorial High School athletes' tent at the meet before Anthony is seen running away.

In another clip, Anthony is seen being apprehended by a local police officer who speaks into his radio confirming that he's 'got the alleged suspect.'

'I'm not alleged, I did it,' replies Anthony, as he is detained by law enforcement.

The public has also been shown the knife involved in the stabbing, as well as blood soaked clothing worn by Metcalf and the deep stab wound in his chest.

The murder case shocked America, and the discussion surrounding the killing of a white teenager by a black peer quickly became racially fraught.

During the trial, Anthony and his legal team claimed he stabbed Metcalf in an act of self-defense after they got into a confrontation during a rain delay at the sporting event.

Metcalf called out Anthony for standing under a tent that did not belong to his school, the Frisco Police Department said.

But prosecutors eviscerated Anthony's self-defense claim that Metcalf attacked him first with video evidence and witness testimony.

Witnesses who were in the tent described Anthony as the aggressor, testifying that Anthony told Metcalf: 'Touch me and see what happens,' provoking Metcalf to push Anthony, who then pulled out a knife and stabbed him in the chest.

Prosecutors said Metcalf's twin brother, Hunter, rushed to his aid as Anthony ran from the scene and later tried to blend into groups of kids who were exiting the stadium.

Anthony sat motionless in court as police body camera footage from the track meet showed Hunter pleading for help after the stabbing.

Jurors then gasped in horror after being shown never-before-seen photos of Metcalf's punctured heart during the trial.

Metcalf was stabbed once, with the knife piercing through his bone in the center of his chest and puncturing the right side of his heart, a medical examiner testified.

Still, while cross-examining the medical examiner, Anthony's lawyers implied that Metcalf impaled himself on the knife. 

He had originally faced between five to 99 years in prison for the murder, but prosecutors agreed to allow the jury to consider 'sudden passion' as a factor when determining his sentence.

'Sudden passion' is a legal term in Texas that allows a criminal to argue they were in an intense emotional state when they committed wrongdoing.

It would have reduced Anthony's sentence to that of a second-degree felony for which he could have served as little as two years behind bars.

However, the jury rejected the argument and spent less than three hours passing its guilty verdict, and another roughly two and a half hours before they handed down their sentence.

Anthony will now have to serve at least half of the sentence before he is eligible for parole.

The teenage killer filed a notice of appeal less than 24 hours after he learned his fate for fatally stabbing Metcalf in the heart.

'We believe there are several important issues for the appellate courts to consider. An appeal is the next part of the legal process and a right afforded every American,' his lawyer, Mike Howard, previously told TMZ.
