The father of the teen boy arrested in the mass shooting at a high school in Winder, Georgia, has also been arrested, held accountable for his son Colt Gray's actions.

Colin Gray faces charges including four counts of involuntary manslaughter, two counts of second-degree murder, and eight counts of cruelty to children. These charges stem from allowing his son to possess a weapon.

The FBI first investigated Colt Gray in May 2023 after receiving a tip about a school shooting threat via Discord, a gaming chat platform.

Colin Gray told investigators he had been teaching his son about "firearms and safety" and how to hunt. He stated that if his son had made any threats, he "would be mad as hell and then all the guns would be taken away."

Colt denied making threats. After the investigation, Colin Gray purchased his son an AR-15-style rifle as a gift.
