The father of 14-year-old student Colt Gray, the suspect in the Georgia school shooting on Wednesday, September 4, has been arrested.

“In coordination with District Attorney Brad Smith, the GBI has arrested 54-year-old Colin Gray in connection with the shooting at Apalachee High School. Colin is Colt Gray’s father,” the Georgia Bureau of Investigation said in a post on X on Thursday, September 5.

According to authorities, Colin was charged with four counts of manslaughter, two counts of first-degree murder and eight counts of child abuse. His son Colt was charged with four counts of first-degree murder.

At a press conference on Thursday evening, authorities said the charges against Colin were based on the fact that “Mr. Gray knowingly permitted his son Colt to possess a firearm.”

Four people were killed in the September 4 shooting at Apalachee High School in Winder, Georgia: students Mason Schermerhorn (14) and Christian Angulo (14) and teachers Richard Aspinwall (39) and Christina Irimie (53). According to the GBI, autopsies of the four victims were performed on Thursday.

The nine people injured in the shooting are expected to make a “full recovery,” according to the press conference.

In May 2023, Colt was questioned by police about his alleged threats to commit a school shooting, the FBI’s Atlanta division said in an earlier statement.

“The father stated he had hunting weapons in the house, but the offender did not have unsupervised access to them. The offender denied making the threats online,” FBI Atlanta said.
