The mother of the suspected gunman in last week’s shooting at Apalachee High School in Georgia says she warned the school the morning of the attack and teachers were already noticing warning signs.

In an interview with ABC News published Tuesday, Marcee Gray said she called the school counselor on the morning of Sept. 4, 2024, the day of the shooting, to warn officials about a disturbing message she had received from her son, Colt Gray.

“The counselor said, ‘I wanted to let you know that one of Colt’s teachers sent me an email this morning saying that Colt alluded to school shootings,'” Gray told the newspaper. “Based on my gut feeling, the text messages and now this email, I need you all to run to the classroom.”

Gray said the last message she received from her son was, “I’m sorry, mom.” She said his father received similar texts, one of which said, “I’m sorry” and “It’s not your fault.”

She also said she had called Apalachee almost a week earlier because “I wanted Colt admitted for inpatient treatment. Colt agreed to that.”

When she heard about the shooting, Gray said, she “fell to the ground and just started screaming.”

“I knew what had happened. I just knew instinctively,” she said, calling what had happened to the victims “unbelievable.”

“If I could take her place, I would,” Gray told ABC News. “I would do it in a heartbeat.”

Fox News Digital has reached out to Gray and the district for further comment.

According to officials, 14-year-old Colt Gray shot and killed students Christian Angulo and Mason Schermerhorn (both 14) and teachers Richard Aspinwall (39) and Cristina Irimie (53). Eight other students and one teacher were injured – seven of them were shot – and are expected to recover.

Marcee Gray’s sister, Annie Brown, told The Washington Post that her sister sent her a text message saying she had spoken to a school counselor before the killings and warned staff of an “extreme emergency.” Brown said Marcee Gray urged her to find her son “immediately” to check on him.

Brown provided screenshots of the text exchange to the newspaper, which also reported that a call log from the family’s shared phone plan showed a call was made to the school at 9:50 a.m. Warrants for Gray’s arrest say the shooting began at 10:20 a.m.

The boy’s grandfather, Charles Polhamus, has told multiple news outlets that Marcee Gray received a text message from her son apologizing on Wednesday. Polhamus told CNN that Marcee Gray drove to Winder, more than 200 miles from Fitzgerald, immediately after the shooting.

Authorities have said Gray’s father, Colin Gray, gave Colt access to the AR-15-style semi-automatic rifle used in the shooting. It’s unclear how Gray got the gun onto campus or what he did with it in the two hours between the start of classes at 8:15 a.m. and the first shot.

Colt Gray was charged as an adult last week with four counts of first-degree murder. If convicted, he faces a maximum sentence: life in prison without parole or life in prison with the possibility of parole.

Colin Gray is the first parent of a school shooting suspect to be charged in Georgia, District Attorney Brad Smith said Friday. Colin Gray has been charged with second-degree murder, involuntary manslaughter and child abuse for giving his son the gun.

Colin Gray is in jail in Barrow County after skipping bail in a brief court hearing Friday in Winder. Colin Gray is being held in a juvenile detention center after skipping bail. He has not been charged and has not entered a guilty plea.

It is unclear whether Barrow County school authorities knew before the shooting that Colt and Colin Gray had already been questioned by a deputy sheriff in neighboring Jackson County in May 2023 after a shooting was reported online at a middle school attended by then-13-year-old Colt Gray.

Colin Gray told the investigator at the time that Colt had access to unloaded guns in the house but knew “how to use them and how not to use them.” He also said that his son had been having problems since separating from his wife and that Colt had been bullied at school.
