Tragic final social media post of 17-year-old student who died in twin brother’s arms after being stabbed

The last thing 17-year-old Austin Metcalf said on social media before he was stabbed to death has been revealed.

Metcalf, a high school American football student, was fatally stabbed during a track and field meet at Kuykendall Stadium in Frisco, Texas, on Monday (2 April).

Police said there was an 'altercation between two students' which was reportedly started over seating arrangements, at around 10am local time.

Fellow student Karmelo Anthony, 17, was arrested at the scene, and the arrest warrant affidavit, obtained by NBC DFW, states that Metcalf asked Anthony to move seats in the pop-up tent.

Police said that Metcalf 'grabbed Anthony to tell him to move and Anthony pulled out a black knife and stabbed Austin once in the chest'.

“I was protecting myself,” Anthony allegedly told the police. “He put his hands on me.”

Metcalf was a junior at Frisco Memorial High School and his twin brother, Hunter, was present during the incident. He says that his brother died in his arms.

On Monday, Metcalf's last ever post on X was: "Faith that god got me and my work will pay off."

His father Jeff Metcalf told NBC Dallas-Fort Worth: "I could see all the blood, and I saw where the wound was, and I was very concerned, so I had to find his brother, and we rushed to the hospital.

"And we prayed, and it’s God’s plan, I don’t understand it, but they weren’t able to save him. This is murder."

Jeff has since launched a GoFundMe in 'honour' of his son.

The boy's mother, Meghan Metcalf, said to WFAA that Hunter 'was trying to save his brother'.

"I think he said he saw when he took his last breath before the CPR came back in," she said.

"From what I heard, [Austin] was unresponsive for five minutes, they were able to revive him a little, but it was too little, too late."

Hunter added: "He didn't deserve it. I know people that lose their family members all the time, but I just didn't know it would be mine so soon. My best friend, my brother, my whole life."

School security expert and former Dallas ISD Chief of Police Craig Miller claims that Frisco Independent School District 'doesn't use metal detectors in a school'.

"So it would be unusual for them to have them in an athletic event of this nature," he told NBC DFW.

Anthony remains in custody at Frisco Jail and his bail is set at $1,000,000, according to People.
