Last month, Metcalf was stabbed to death at a high school track meet after reportedly telling Karmelo Anthony, 17, that he was sitting in the wrong seat. Anthony has been charged with first-degree murder and, according to an arrest warrant, told police of the fatal stabbing, “I did it.”

Anthony will be tried as an adult, since Texas is a concurrent jurisdiction state, according to Capital B. The laws allow prosecutors to charge minors, typically 16 or 17 years old, as adults with certain crimes.

The Collin County District Attorney’s Office, which is north of Dallas, is prosecuting the case of Metcalf’s apparent murder. Anthony was charged with first-degree murder in April, but a grand jury will review the evidence and decide whether to formally indict on that charge, or on a lesser charge like manslaughter, Capital B reported.

If Anthony is convicted of first-degree murder, he could face life in prison with a chance at parole after 40 years. He will not face the death penalty.
