The father of a teen football star who was stabbed to death at a college track meet has challenged a school’s decision to let his killer graduate.

Jeffrey Metcalf has filed a formal complaint regarding Centennial High School’s decision to present Karmelo Anthony with his diploma, despite facing accusations of murdering his son, Austin.

The incident took place at the stadium in Frisco, Texas, where 18-year-old Anthony allegedly drew a knife on 17-year-old Austin on April 2. Tragically, Austin bled out in the arms of his twin brother as a result.

The sickening attack has since sparked a toxic culture war as some rowed in behind the attacker and raised over $500,000 for his defense.

According to a spokesperson for the perpetrator, Jeffrey has formally contested the school’s choice to grant Anthony his diploma, despite his admission to the heinous crime.

Dominque Alexander continued: ‘Now you have a father filing a complaint to the TEA (Texas Education Agency).’

It is unclear what the filing means in practice, but it is understood to be one of few ways the grieving father can contest the graduation.

The confrontation between Anthony and Metcalf stemmed from Anthony sitting under the team tent of a school he did not belong to. When Metcalf, who attended Memorial High School. asked Anthony to move, the murder suspect pulled out a knife and stabbed Metcalf in the chest

Frisco Independent School District had wanted to expel Anthony over the killing of Austin, a student at nearby Memorial High School.

An expulsion would have automatically meant he would not graduate. But hours after a dramatic press conference last month Alexander said the school reversed the move.

It is understood Anthony will still not be allowed to participate in the ceremony or walk on the stage as he remains under house arrest. Frisco ISD declined to comment.

Alexander said last week: ‘We are in arrangements of doing an early gradation. They have agreed to allow him to graduate. They were literally trying to expel him – period.’

Anthony’s family claimed they were experiencing financial hardship in order to talk a judge into lowering his bond so the 17-year-old could be released from jail in April

Anthony fled the track scene after the horrific attack, leaving Austin to bleed out in his twin brother’s arms in the stands.

He was arrested by officers and confessed ‘I did it’ when he was taken into custody. He has since tried to claim self-defense.

Outrage spread after the teen’s bond was lowered from $1million to $250,000, securing Anthony’s release from jail.

During the bond hearing, Anthony’s father testified about their financial hardship since he son became a murder suspect. 

DailyMail.com exclusively reported on the $900,000 home in a gated community the Anthony’s were renting while claiming to be poor.

One neighbor said: ‘Not good. Not good. I don’t think he should be out. I don’t understand why he had a knife?

‘My kids were in track. Your tents, for you school, you don’t sit under another school’s tent.

‘That is not done because everyone leaves their stuff there while they’re out on events.

‘Why would you stab someone? And now he’s a few doors down. It’s very scary. Like could he rob houses? I don’t know.’

Austin’s twin brother Hunter held him in his arms and tried to stop the bleeding after the stabbing April 2

The neighbors told DailyMail.com that they did not want Anthony living in their exclusive enclave.

‘The best thing they can do is move,’ one said. ‘I think that would be best for everyone.’

Anthony eventually did leave the house, claiming his address had been leaked online and he was no longer safe. He is now at an undisclosed location.
