Now both Colt, 14, and Colin Gray, 54, are charged in the killings of two students and two teachers Wednesday at Apalachee High School in Barrow County, outside Atlanta. Nine others were hurt, seven of them shot. The teen is charged with murder, and his father is accused of second-degree murder for providing his son with a semiautomatic, AR 15-style rifle used to kill children. Arrest warrants say the elder Gray did so knowing his son "was a threat to himself and others."
Jackson County authorities ended their inquiry into Colt Gray a year ago, concluding that there wasn't clear evidence to link him to a threat posted on Discord, a social media site popular with video gamers. The records from that investigation provide at least a narrow glimpse into a boy who struggled with his parents' breakup and at the middle school he attended at the time, where his father said others frequently taunted him.
"He gets flustered and under pressure. He doesn't really think straight," Colin Gray told the investigator on May 21, 2023, recalling a discussion he'd had with the boy's principal.
Shooting guns and hunting, he said, were frequent pastimes for father and son. Gray said he was encouraging the boy to be more active outdoors and spend less time playing video games on his Xbox.
When Colt Gray killed a deer months earlier, his father swelled with pride. He showed the investigator a photo on his cellphone, saying: "You see him with blood on his cheeks from shooting his first deer."
"It was just the greatest day ever," Colin Gray said.
An eviction upended the Grays' family in summer 2022. On July 25 of that year, a sheriff's deputy was dispatched to the rental home on a suburban cul-de-sac where Colin Gray, his wife, Colt and the boy's two younger siblings lived. It was following the eviction, he said, that his wife left him, taking the two younger siblings with her.
Colt Gray "struggled at first with the separation and all," said the father, who worked a construction job.
"I'm the sole provider, doing high rises downtown," he told the investigator. Two days later, there was a follow-up interview with Colin Gray while he was at work. He said by phone: "I'm hanging off the top of a building. ... I've got a big crane lift going, so it's kind of noisy up here."
