ATLANTA (AP) — The student accused of killing four people in a Georgia high school shooting rode the school bus that morning with a semiautomatic rifle concealed in his backpack, investigators confirmed Thursday.
Colt Gray then left his second-period classroom after getting permission to go to the front office at Apalachee High School but hid from teachers in a bathroom before emerging to begin the assault, according to the Georgia Bureau of Investigation and Barrow County Sheriff Jud Smith.
The new details fill in some key questions about how the 14-year-old got a gun that could not be folded down into the school in Winder, northeast of Atlanta, before killing two students and two teachers. Another teacher and eight other students were injured.
Marcee Gray, the suspect's mother, says that she called the school in a panic on the morning of Sept. 4 after getting a text message from her son saying “I'm sorry." She said Colin Gray, the boy’s father, received similar text messages that morning.
Marcee Gray said school officials told her on that call that they were already worried about her son's behavior. He had enrolled at the school after it had already begun Aug. 1, Smith has said.
“The counselor said, ‘Well, I want to let you know that earlier this morning, one of Colt’s teachers sent me an email that said Colt had been making references to school shootings,” Gray said in an interview with ABC News published Tuesday.
Marcee Gray and other relatives on her side of the family have said they had sought the school's assistance the week before the shooting to get psychiatric treatment for Colt Gray.
“I wanted Colt to be admitted to an inpatient treatment," Gray told ABC News. "Colt was on board with it.”
A school employee went to look for Gray the morning of the shooting, but confused him with a fellow student with the same last name and similar first name, police and a student said. By that time, Gray had left his second-period algebra class, going to the bathroom instead of the front office, investigators said.
Colt Gray is charged as an adult with four counts of murder, and District Attorney Brad Smith has said more charges are likely to be filed against him in connection with the wounded. Authorities have also charged his father, Colin Gray, alleging that he gave his son access to the gun when he knew or should have known that the teen was a danger to himself and others.
The 13,000 students at Barrow County's other schools returned to class Tuesday. Officials have not announced a restart date for the 1,900 students who attend Apalachee.
