Authorities have not offered any motive or explained how the suspect obtained the gun and got it into the school of roughly 1,900 students in a rapidly developing area on the edge of metro Atlanta’s ever-expanding sprawl.
It was the 30th mass killing in the U.S. so far this year, according to a database maintained by The Associated Press and USA Today in partnership with Northeastern University. At least 127 people have died in those killings, which are defined as events in which four or more people die within a 24-hour period, not including the killer — the same definition used by the FBI.
Prior cases have emerged in which someone who was once on the FBI’s radar but was not arrested went on to commit violence.
A month before Nikolas Cruz killed 17 people at the Parkland, Florida, high school in 2018, the bureau received a warning that he had been talking about committing a mass shooting. The FBI also investigated a tip about the person later convicted in a deadly 2022 shooting at a gay nightclub in Colorado.
The pattern underscores the challenges law enforcement faces in trying to determine when concerning behavior crosses into a crime. Investigators sift through tens of thousands of tips every year to try to determine which could yield a viable threat. Cases such as the Georgia school shooting prompt fresh questions about whether more intensive investigative work might have averted the violence.
The sheriff’s report says investigator Daniel Miller spoke to the boy and his father May 21, 2023. The father said his son had access to guns in the house.
“I mean they aren’t loaded, but they are down,” Gray’s father said, according to the interview transcript.
He described a photo on his cellphone from a recent hunting trip with his son: “You see him with blood on his cheeks from shooting his first deer.” Gray’s father called it “the greatest day ever.”
The teen told Miller he stopped using Discord a few months earlier after his account got hacked.
“I gotta take you at your word and I hope you’re being honest with me,” Miller replied.
A phone number associated with the account was linked to a different person in another Georgia city, the report said. The account’s profile name, written in Russian, translated to Lanza. The investigator noted that Adam Lanza was the perpetrator of the 2012 mass shooting that killed 26 people at Sandy Hook Elementary School in Newtown, Connecticut.
The sheriff’s office alerted local schools for continued monitoring of the teen. But the investigator concluded that he “could not substantiate the tip I received from the FBI to take further action.”
