Georgia emergency officials have released records of 911 calls and police responses to last week’s shooting at Apalachee High School that left two teachers and two students dead.

Emergency recordings and dispatch records analyzed by CNN and obtained from the Barrow County Sheriff’s Office under the Freedom of Information Act reveal conversations between dispatchers and authorities reporting the high school shooting, the number of people injured and calls from parents concerned about the safety of their children.

Audio recordings and dispatch logs describe the events as authorities say Colt Gray, 14, fired an AR-15-style rifle at a high school in Winder, Georgia, killing four people. Nine other people injured — eight students and one teacher — are expected to recover, authorities said.

“Active shooter!” an officer can be heard shouting in one audio clip as he talks to a dispatcher, who repeats the phrase to him. Another officer can also be heard calmly responding: “That’s right. We have an active shooter at Apalachee High School.”

In another recording, the officer, sounding slightly out of breath, tells the dispatcher that the suspect is in custody and orders her to “hang up the ambulance.” He can be heard confirming that emergency services are on their way to the high school.

“A parent is on the phone with his child,” an officer says urgently in another recording. “They’re in an art studio, locked up.”

A male caller told dispatchers in another recording that his daughter, a school counselor, was working with a student in a trailer “next to where the shooting occurred.” He said his daughter tried to hide behind a desk with the student.

The man can be heard saying: “I don’t know what the situation is – if there’s one trailer or multiple trailers – that helps, but I want them to know that she’s in the trailer and she can’t, you know, close the doors, and if they can check the trailers … hopefully they can check that and get her out.”

The officer on duty confirmed whether the student was with a psychologist, to which the caller replied, “Yes, but she didn’t want to call, she didn’t want to make noise.”

The deadly Sept. 4 attack marked the 45th school shooting of 2024 and the deadliest U.S. school shooting since the March 2023 massacre at The Covenant School in Nashville that left six people dead.

Colt Gray, who authorities say confessed to the attack at Winder High School, is charged with four counts of murder and will be tried as an adult. His attorney, Alfonso Kraft Jr., declined to comment Wednesday when reached by phone.

Colt Gray’s father, 54-year-old Colin Gray, has been charged with two counts of second-degree murder, four counts of involuntary manslaughter and eight counts of child abuse, according to the Georgia Bureau of Investigation. Authorities have accused him of knowingly giving his son permission to possess a gun.

Second-degree murder charges are against two 14-year-olds killed, Christian Angulo and Mason Schermerhorn, according to the Barrow County District Attorney. Two teachers, Richard Aspinwall, 39, and Cristina Irimie, 53, were also killed.

CNN has contacted Colin Gray’s lawyers.

Colt Gray is not eligible for the death penalty if convicted because he is a juvenile, state Judge Currie Mingledorff said during a Sept. 6 hearing. Colin Gray faces up to 180 years in prison if convicted of all 14 charges.

Colt Gray’s mother, Marcee Gray, called the school before the Sept. 4 shooting and asked administrators to check on her son after he texted her: “I’m sorry mom,” she said.

That’s when the school counselor informed the mother that her son had made references to school shootings, she told ABC News. As a result, she and the teen’s grandfather made the 200-mile trip from Fitzgerald to Winder, Georgia.

That day, an unknown person called Apalachee High School, warning of shootings at five schools. Authorities said the first was Apalachee High School.

Colt Gray rode the bus to school that morning with a gun hidden in his backpack “like it was … a school project,” Barrow County Sheriff Jud Smith told CNN station WXIA.

The teen was allowed to leave his Algebra 1 class from his second period with his belongings before he tried to return to the classroom, the Georgia Bureau of Investigation reported Thursday. But the doors were locked, so he went to an adjacent classroom and started shooting, according to the student.

At about 10:20 a.m., the Barrow County Sheriff’s Office learned of the shooting and arrived at the high school a short time later with two officers. The suspect surrendered after the officer confronted him and was arrested, Barrow County Sheriff Jud Smith said.

Colin Gray purchased the gun used in the alleged shooting in December 2023 as a Christmas gift for his son, according to two law enforcement sources with direct knowledge of the investigation.

During a search of the Gray home, authorities found documents they believe were written by the suspect that reference previous school shootings, including the 2018 massacre at Marjory Stoneman Douglas High School in Parkland, Florida, a law enforcement source told CNN.

Barrow County School System administrators plan to “phase in reopening” Apalachee High School the week of Sept. 23, Superintendent Dallas LeDuff said in an update Friday.

Mental health support will be available on campus, the district said, and final reopening plans will be developed by the county school system.

This is a developing story that will be updated.
