A 16-year-old has been charged with murder in the shooting of a student at a Harford County high school.

The teen is being held at the Harford County Detention Center. He’s also charged with first- and second-degree assault and use of a firearm in the commission of a felony/crime of violence.

The Baltimore Banner is not naming the teen because he is a juvenile.

Harford County Sheriff Jeffrey Gahler said Saturday in announcing the arrest that the 16-year-old, who was in his first day at Joppatowne High School, and the slain student, Warren Curtis Grant, were “known to each other,” and there’s no ongoing threat to the school or other students.

At a news conference Friday, Gahler said Grant was taken to the Johns Hopkins Hospital in Baltimore, where he died several hours later.

Gahler said the shooting stemmed from a fight between the 16-year-old and Grant at about 12:36 p.m. Fellow students took Grant from the restroom where the fight took place into a hallway, where school personnel treated him until his transport to the hospital.

Deputies caught the 16-year-old in a nearby neighborhood shortly after the shooting, Gahler said.

The shooting forced a lockdown, then evacuation, of the school. Harford County School Superintendent Sean Bulson said Friday that students would be offered counseling and assistance, but he wasn’t sure what impact the incident would have on Monday’s classes.
