The 14-year-old suspect accused of gunning down four people and injuring multiple others at Apalachee High School will have his first court appearance on Friday.

Colt Gray surrendered to two school resource officers at the scene on Wednesday morning, and is currently being held at Gainesville Regional Youth Detention Center, Atlanta News First reported.

There are no further details available about his Friday court appearance, the outlet said.

The young teen is expected to be charged with murder and tried as an adult for the deaths of teachers Richard Aspinwall, 39, and Christina Irimie, 53, and students Mason Schermerhorn, 14, and Christian Angulo, 14, officials said.

Nine other victims were injured in the shooting. They are all expected to survive.

A chilling video shows students casually walking down the school hallway where a gunman opened fire -- killing two fellow students and two teachers -- with his assault rifle lying on the floor.

The gun allegedly used by Apalachee High School shooter Colt Gray appears to be an AR-15-style weapon that can be seen in a video of the shooting aftermath.

The video shows the black rifle lying on the ground with a magazine attached and another tan magazine next to it in the school's hallway. A body under a white sheet can also be seen.

The manufacturer of the gun is unknown, but police confirmed that Gray, 14, allegedly used the AR-style weapon around 10:30 a.m. on Wednesday to commit the mass shooting.

A non-modified, magazine-fed, gas-operated, semi-automatic AR-15 fires at a rate of 45 rounds per minute.

It remains unclear if the rifle was modified in any way, including with a bump stock, which allows semi-automatic firearms to fire close to a fully automatic weapon.

Bump Stocks, which Las Vegas shooter Stephen Paddock used in the deadly mass shooting in US history, are legal in Georgia.

Gray allegedly killed two students and two teachers with the rifle during his rampage and injured nine others.

Droves of students and residents came together to mourn Wednesday's tragic shooting that left two students and two teachers dead at Apalachee High School after accused gunman Colt Gray, 14, opened fire.

Hundreds gathered in Jug Tavern Park in downtown Winder, Ga., as traumatized locals and students tried to make sense of the tragedy.

One sophomore who was near the gunfire called it "horrible."

“I don’t think I want to be here for like a long time now,” she said.

Colt Gray, the 14-year-old student accused of killing four people and injuring nine in the mass shooting at Apalachee High School, will be booked Wednesday night, Georgia Bureau of Investigation Director Chris Hosey said.

The GBI director added he wasn't sure when the alleged gunman would make his first court appearance -- but it would be "in a reasonable amount of time."

No other casualties are expected from Wednesday's mass shooting at Apalachee High School, Barrow County Sheriff Jud Smith said during an evening press conference Wednesday night.

Four people — two students and two teachers — were killed when alleged gunman Colt Gray, 14, opened fire at the Winder, Ga.

The weapon used was an AR-15-style rifle, officials said.

Gray remains in police custody and was charged with murder after the tragic mass shooting. He will be tried as an adult.

The four victims — two students and two teachers — killed when accused gunman Colt Gray, 14, opened fire inside Apalachee High School Wednesday were identified by Georgia Bureau of Investigation Director Chris Hosey at an evening press conference.

Students Mason Schermerhorn and Christian Angular, both 14, were gunned down along with math teachers Richard Aspinwall and Christina Irimie, officials said.

Gray allegedly used an AR-15-style rifle, they added.

Colt Gray, the alleged teen gunman who killed four people at a Georgia high school, has been on the FBI's radar since last year -- when he was interviewed in connection to online school shooting threats, the bureau revealed.

In May 2023, the FBI's National Threat Operations Center received several tips about the threats to commit a school shooting -- with the harrowing remarks including photos of guns, according to a Wednesday night statement from the bureau's Atlanta division.

The Jackson County Sheriffs' Office located Colt Gray, then just 13, and interviewed him and his father.

His dad said he had hunting guns in the house -- but Gray didn't have unsupervised access to them, according to the statement

Gray also denied making online threats.

Officials, however, alerted local schools "for continued monitoring" of Gray, per the statement.

A 14-year-old student with autism was identified by family members as one of four victims killed in Wednesday's mass shooting at a Georgia high school.

Mason Schermerhorn's desperate relatives had circulated his photo on social media after they couldn’t reach the teen after the shooting, according to WSBTV.

“If he is escalated, PLEASE use a calm voice with him,” family members posted online. “Let him know his mom is looking for him for reassurance.”

Schermerhorn's mother later told the outlet that her son was among the dead at Apalachee High School.

Schermerhorn, another student and two teachers were gunned down in the shooting, allegedly by 14-year-old suspect Colt Gray.

Another nine victims, including special education teacher David Phenix, were hospitalized with gunshot wounds, law enforcement said.

Eight of the nine people who were injured in Wednesday's school shooting were students, the Georgia Bureau of Investigation said.

A teacher was also wounded during the mass shooting at Apalachee High School.

Two students and two teachers were killed in the massacre, which is Georgia's deadliest school shooting to date.

Colt Gray, 14, was arrested and charged with murder.

Lyela Sayarath, a junior at Apalachee High School, described alleged school shooter Colt Gray, 14, as "pretty quiet," she told CNN.

"He never really talked. He wasn't there most times. Either he didn't just come to school or he would just skip class," the 16-year-old student said.

"Even when he would've talked it was just one-word answers or short statements."

The junior, who was sitting next to the alleged gunman in Algebra I moments before the shooting, added she wasn't surprised that Gray was the alleged gunman.

"Just because of when you think of shooters and how they act or things that they do, it's normally the quiet kid," Lyela said.

Lyela Sayarath, a junior at Apalachee High School, told CNN that she was sitting next to alleged shooter Colt Gray, 14, moments before Wednesday's massacre.

The 16-year-old student said Gray left the classroom at the beginning of their Algebra I class in the morning.

Sayarath said the suspected mass shooter knocked to be let back in since the door automatically locked behind him.

A girl went to open up the door for him -- but quickly jumped backward after presumably seeing Gray was armed.

“I guess he saw we weren’t going to let him in," Lyela told CNN. "And I guess the classroom next to me, their door was open so I think he just started shooting in the classroom."

The junior said students in her Algebra class hid behind desks when they heard gunshots, a harrowing experience she described as "just one after another."

“When we heard it, most people just dropped to the floor and like kind of crawled in an area, like, piled on top of each other,” she said.
