A HIGH school athlete who was stabbed in the heart and died in his twin’s arms shared a heartbreaking post before his murder.

Austin Metcalf, 17, was killed on April 2 after a horrific attack in the bleachers at a high school track and field meet.

Star athlete Austin, 17, was at the track meet with his twin brother, Hunter, when he was attacked in the stands.

His alleged killer, 17-year-old Karmelo Anthony, was arrested and charged with murder.

The attack stemmed from an altercation over seating, Austin’s father local NBC affiliate KXAS reported. 

Right after Metcalf was stabbed, his twin brother desperately tried to save him. 

“I tried to whip around as fast as I could,” Hunter told ABC affiliate WFAA. 

He said he held onto his brother and tried to perform CPR but was unable to help him.

Just two days before the stabbing in Frisco, Texas, Metcalf had written about his faith in a post on X.

“Faith that God got me and my work will pay off,” he wrote.

A student from Memorial High School, who was also a member of the school’s football team, had recently participated in the shot put and discus events prior to his tragic death.

He reportedly didn’t know his alleged attacker before the murder.

Metcalf’s father, Jeff, and mother, Meghan, are mourning the young teen’s death. 

“This tragedy has shaken me, family, and friends to the core,” Jeff wrote in a Facebook post. 

“I trust God will bring us through the tough times ahead.”

The grieving father shared a GoFundMe link for followers to help him and his family out during this challenging time.

“I can’t describe the range of emotions I am feeling. I pray God will guide our paths moving forward,” he concluded his post. 

The fundraiser quickly raised over $100,000.

Jeff told KXAS his son was “a leader of men” and had a “bright future” ahead of him.

And his mom called his murder a “senseless act.”

“It doesn’t make any sense,” she said through tears.

“Just because the kid was mad, my son isn’t here anymore, and I just don’t understand it.”

Meghan described her son as “the most amazing kid” and said he had aspirations of playing college football.

“His life was going to the gym and working out and being a leader on the football team,” the tearful mother said.

“He had such a drive that you don’t usually see in a kid.”

Meghan said Hunter and Austin were the best of friends – and Hunter saw his brother take his last breath. 

“I’m so worried about my son because he’s going to have to face the world alone now,” she said.

Brook Fesco, the high school principal where Austin was enrolled, sent a letter to the school district encouraging parents to provide support to their children during this challenging period.

“As a parent, your guidance and support will be important in helping your child process grief,” she wrote.

“Talking about this together, face-to-face, will give you a chance to discuss how your family understands and copes with loss.”

Fesco said the school honored Austin during second period on Thursday morning and will offer grief counseling for all those who need it.
