Authorities have identified the four victims killed in a shooting at a Georgia high school Wednesday morning, when a student opened fire inside the school.

Georgia Bureau of Investigation (GBI) Director Chris Hosey said two 14-year-old students and two teachers were killed in the shooting.

Hosey identified two students killed at Apalachee High School: Mason Schermerhorn and Christian Angulo, both 14. Hosey said math teachers Richard Aspinwall and Christina Irmie were also killed in the shooting.

According to Channel2Now, Schermerhorn, who was autistic, allegedly ran away from school after school.

One of the teacher victims, Aspinwall, was also a football coach at the school.

“Coach Aspinwell was one of the kindest teachers I have ever met. He always let me know that if I needed help with anything, he was there for me,” one student wrote in an Instagram tribute.

“He was so funny, spoke with pride about his wife and children, and showed all his students that he cared about them,” the post continued.

On Wednesday, authorities identified Colt Gray, now 14, as the gunman who shot and killed two students and two teachers at Apalachee High School. Gray surrendered to authorities and was captured after the rampage.

An AR-platform weapon was used in the shooting, Hosey said.

“As a follow-up to the joint statement just released, the individual identified as the 13-year-old is the same individual in custody in connection with today’s shooting at Apalachee High School,” the FBI said.

Investigators are still trying to determine if anyone specifically was targeted, but they are not aware of any known connection between Gray and the victims.

“Within minutes, police and two school resource officers were on the scene,” Barrow County Sheriff Jud Smith told reporters at a news conference Wednesday afternoon.

According to Smith, Gray will be charged with murder and prosecuted as an adult.

Authorities say there is no evidence that another shooter was involved in the shooting. Detectives are actively pursuing leads on possible associates of the shooter.

In a joint statement, the FBI’s Atlanta office and the Jackson County Sheriff’s Office said the agency’s National Threat Operations Center received an anonymous tip about threats posted online regarding a possible school shooting in May 2023.

According to the authorities, the threats contained images of weapons.

Within 24 hours of receiving the anonymous tip, investigators determined the threats originated in Georgia and the case was referred to the sheriff’s office.

“The Jackson County Sheriff’s Office located a possible victim, a 13-year-old male, and interviewed him and his father,” the FBI said. “The father stated he had shotguns in his home, but the victim did not have unescorted access to them.”

According to authorities, the boy denied making the threats and local schools were alerted to monitor the child.

“At that time, there was no probable cause for an arrest or to take additional law enforcement action at the local, state, or federal level,” the FBI said.

Gray has been booked and is currently being held at the Barrow County Detention Center.

The shooting victims are expected to recover and the Barrow County Sheriff’s Office does not anticipate any additional fatalities at this time.
