Karmelo Anthony, the 18-year-old accused in the stabbing of Austin Metcalf, a prominent track athlete from Frisco, Texas, has been charged with first-degree murder by a grand jury as of Tuesday. 

“My team has been diligently presenting evidence to the grand jury over the past few weeks. Today, I summarized that evidence, requesting a first-degree murder indictment against Karmelo Anthony, which the Grand Jury has granted,” stated Collin County District Attorney Greg Willis. 

“This indictment propels the case formally into the judicial system,” he added. “Moving forward, we will continue to strive diligently and impartially to ensure justice is served. The court will establish the trial schedule, and we will be prepared when the moment arrives.”

In the next moment, a witness told police that Anthony “reached into his bag and the male took a knife out of the bag and stabbed Austin.”

The witness told the officer that Anthony deserted the scene following the stabbing. Metcalf died in his twin brother’s arms.

Anthony allegedly told the responding school resource officer, who cuffed him upon arrival at the scene, that he was protecting himself. The officer also noted blood on Anthony’s left middle finger. 

One officer at the scene referred to Anthony as the alleged suspect, and Anthony made a “spontaneous statement,” according to the report: “I’m not alleged, I did it.”

After initially being held on $1 million bond, Anthony’s bond was reduced to $250,000, and he was released to home confinement. A trial date has not yet been set. 

The Anthony family’s spokesperson did not immediately return a comment request.
