A 14-year-old student suspected of gunning down four people at his Georgia high school on Wednesday turned himself in immediately after a deputy assigned to the school “attacked” him, authorities said.

The shooter quickly realized that if he didn’t give up, it would end in an OIS, said Barrow County Sheriff Jud Smith at a press conference, using the acronym for a police-involved shooting.

“He threw himself on the ground and the deputy arrested him,” Smith said.

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

Hosey said nine people were also injured in the shooting. He did not name the victims.

Hosey said the teen will be charged with murder and tried as an adult. NBC News does not typically name people accused of a crime.

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

It was not immediately clear what type of weapon was used or how many shots were fired, Smith said.

The condition of most of the nine injured was initially unknown.

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 his condition was stable after surgery.

A North Georgia Medical Center spokesman said eight patients were admitted to three of the hospital’s hospitals, 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 “as we cooperate fully to get answers to the many questions we have about the incidents here.”

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

“These children hurt my heart,” he said. “This community hurts my heart.”

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

Republican and Democratic presidential candidates reacted to the shooting. Donald Trump called the shooter “sick and deranged” on his social media platform and Kamala Harris declared at a rally in New Hampshire: “We must end this epidemic of gun violence.”

Georgia Governor Brian Kemp said the shooting left him “heartbroken.”

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