The father of the teen suspected in the Georgia school shooting has been arrested, the Georgia bureau of investigation has said.

Colin Gray, 54, was arrested by the bureau in connection to the shooting at Apalachee high school. Colin is the father of Colt Gray, the 14-year-old who is suspected of fatally shooting two students and two teachers with an assault-style rifle at the high school on Wednesday.

He is charged with four counts of involuntary manslaughter, two counts of second degree murder and eight counts of cruelty to children, the Georgia bureau said.

“His charges are directly connected with the actions of his son and allowing him to possess a weapon,” Chris Hosey, director of the Georgia bureau of investigations, told reporters on Thursday evening.

“What are we facing? Heartbreak. A young person brought a gun into a school, committed an evil act and took lives, and injured people not just physically but mentally,” said Barrow county sheriff Jud Smith during the news conference.

The teenager has been charged as an adult in the deaths of the school students Mason Schermerhorn and Christian Angulo, both 14, and educators Richard Aspinwall, 39, and Christina Irimie, 53, the director of the Georgia bureau of investigation, Chris Hosey, said.

At least nine other people – seven students and two teachers – were taken to hospitals with injuries and all are expected to make a full recovery, Smith said.

Colin Gray is being held at the Barrow county detention center.

More than a year ago the alleged shooter was interviewed by Georgia police after they received tips about online posts threatening a school shooting. Police did not have enough probable cause to arrest him then, according to the Georgia bureau of investigation.

In that 2023 inquiry, the father said he had hunting guns in the house but that his son did not have unsupervised access to them, and the son denied making the threats online, the FBI said.

Georgia state and Barrow county investigators say the younger Gray used an “AR platform style weapon”, or semiautomatic rifle, to carry out the attack in which two teachers and two 14-year-old students were killed.

It remained unclear how the shooter obtained the weapon.

Investigators have yet to comment on what may have motivated the first US campus mass shooting since the start of the school year.

Jackson county sheriff’s investigators closed the case after being unable to substantiate that either Gray was connected to the Discord account where the threats were made, and did not find grounds to seek the needed court order to confiscate the family’s guns, according to police reports released by the sheriff’s office on Thursday.

“This case was worked, and at the time the boy was 13, and it wasn’t enough to substantiate,” Janis Mangum, Jackson county sheriff, said in an interview. “If we get a judge’s order or we charge somebody, we take firearms for safekeeping.”

The younger Gray was taken into custody shortly after the shooting and was being held without bond at Gainesville regional youth detention center, Glenn Allen, the Georgia department of juvenile justice communications director, said on Thursday.

His arraignment is set for Friday morning before a Georgia superior court judge in Barrow county by video camera.

While parents are not usually held criminally liable if their child shoots someone, recent high-profile events are evidence that they could face charges in the future. In November 2023, Deja Taylor of Virginia was sentenced to 21 years on two federal charges after her then six-year-old son shot his teacher in January.

The elder Gray’s arrest also comes months after the unprecedented conviction of the parents of a Michigan high school student who shot and killed four students on 30 November. In February Jennifer Crumbley was convicted on four counts of involuntary manslaughter. The next month, her husband James Crumbley was convicted on the same charges. The pair was sentenced to serve at least 10 years in prison.

“I didn’t really think about what precedent it was setting,” Karen McDonald, the prosecutor for Oakland county who brought the case against the Crumbleys, told CNN on Thursday. “If nothing else I would’ve hoped that the highly publicized details of this case would steer parents and make them think twice.”

“It’s enraging that this could still happen when it’s so easily preventable,” she continued.
