Teen in "serious condition" after shooting inside Joppatowne High School

BALTIMORE -- A teen is in "serious condition" after a shooting inside Joppatowne High School Friday afternoon.

According to the Harford County Sheriff's Office, the fight occurred between two students in a bathroom inside the school. The suspect, a 16-year-old boy, is accused of shooting a 15-year-old boy. The incident happened around 12:36 p.m.

Gahler said the teen victim was flown by medical helicopter to the hospital, where he is in serious condition. The alleged teenage gunman ran from the school, but was captured a short time later.

Harford County Sheriff Jeffrey Gahler said the police response was robust.  WJZ crews on the scene described a massive law enforcement presence, including several ambulances and a helicopter. The Harford County Executive also visited the scene. 

"Within 15 minutes, more than 100 police officers were here from all of our partner agencies," Gahler said.   

In a statement, Harford County Public Schools said in part, "The Harford County Sheriff's Office has responded to the school for an isolated incident on campus today. There was a fight on campus to known parties. A weapon was brought onto campus and used in the incident. The HCSO and HCPS are working together to get this information to you."

The school was evacuated after the incident. The HCSO said the incident was isolated, and not an active shooter situation. 

Parents were instructed to pick up their students at Good Shepherd Presbyterian Church, turned into a reunification center. 

Joppatowne is located about 20 miles northeast of Baltimore.  Just three days ago, students returned to the school for the 2024-2025 school year.

"Our hearts are breaking for the victim and the victim's family," said Harford County Schools Superintendent Dr. Sean Bulson. "This should not be happening in schools."
