A 14-year-old student suspected of fatally shooting four people at his Georgia high school immediately surrendered Wednesday after a sheriff’s deputy assigned to the school “attacked” him, authorities said.

The shooter “realized quickly that if he didn’t give up, it was going to end with an OIS,” Barrow County Sheriff Jud Smith said at a news conference, using the abbreviation for an officer-involved shooting.

“He got down on the ground and the officer took him away,” Smith said.

Two teachers and two students were killed after the gunman opened fire around 10:20 a.m. at Apalachee High School, about 45 miles northeast of Atlanta, Georgia, Principal Chris Hosey told reporters.

Nine people were also wounded in the shooting, Hosey said. He did not identify the victims.

Hosey said the teen will be charged with murder and tried as an adult. NBC News does not typically name minors charged with crimes.

A possible motive remained unclear, and Smith said it was not known whether the suspect had specific targets in mind when he allegedly opened fire, Smith said. The sheriff said investigators from his office and the state law enforcement agency were questioning the teen.

According to Smith, it was not immediately clear what type of weapon was used or how many bullets were fired.

The condition of most of the nine injured was not immediately known.

The daughter of one of the victims, golf coach David Phenix, said her father’s hip was shattered after he was hit in the foot and hip. In a Facebook post, she said he was in stable condition after surgery.

A spokesman for North Georgia Medical Center said eight patients were taken to three hospitals in the system, including three with gunshot wounds. Five people had symptoms of a panic attack, the spokesman said.

The superintendent of the Barrow County School District, which includes Apalachee High School, said schools would remain closed for the rest of the week “while we fully cooperate to get answers to the many questions we have about what happened here.”

Smith, who said his children attend school, described the shooting as “personal.”

“My heart hurts for these children,” he said. “My heart hurts for this community.”

“Hate will not triumph,” he added. “Love will triumph.”

The Republican and Democratic presidential candidates responded to the shooting, with Donald Trump calling the gunman “sick and deranged” on his social media platform, and Kamala Harris telling a rally in New Hampshire that “we must end this epidemic of gun violence.”

Georgia Governor Brian Kemp said he was “heartbroken” by the shooting.

“This is a day that every parent dreads, and Georgians around the world will hug their children even tighter tonight because of this painful event,” he said.
