Colt Gray, 14, opens fire at his Apalachee High School in Winder, Georgia. He fatally shot four people and injured several others. 

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

Father 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.    Colt Gray smuggled the rifle into school inside his backpack and opened fire in a math classroom and a hallway.   

There were four  fatalities: two 14-year-old-students,- Mason Schermerhorn and Christian Angulo alongside teachers Richard Aspinwall  and Cristina Irimie. Eleven people were injured.  

Evidence presented during h trial revealed that Gray deliberately planned the attack for months to achieve internet notoriety. Prosecutors showed that he was heavily active in an online "true crime community" and deeply obsessed with previous mass murderers, specifically Parkland school shooter Nikolas Cruz. His electronic devices contained thousands of photos of Cruz.    Gray pleaded guilty to all 55 criminal charges against him, including four counts of malice murder.  

During his sentencing hearing, Gray laughed out loud during on of his surviving victim's impact statements.
