On Monday, authorities released bodycam footage from detectives’ interrogation last year of a man and his teenage son accused of shooting four people to death at a Georgia school.

They were interviewed after online threats about a school shooting were posted. The teen, Colt Gray, 14, was questioned about the online threats and denied making them.

He has been charged with four counts of first-degree murder in connection with Wednesday’s fatal shooting of two fellow students and two teachers at Apalachee High School in Winder.

His father, Colin Gray, 54, is the first parent in Georgia to be prosecuted after a child was accused in a school shooting. He was charged with involuntary manslaughter, second-degree murder and cruelty to children.

Attorneys for the suspects did not immediately respond to requests for comment Monday. Both appeared in court Friday but did not enter pleas.

On Wednesday, the day of the shooting, the FBI and the Jackson County Sheriff’s Office released a statement saying the teen had previously been questioned about a school shooting threat.

The newly released video of the 2023 investigation follows the publication of a transcript by the Jackson County Sheriff’s Office.

The transcript shows that on May 21, 2023, Detective Dan Miller and Deputy Sheriff Justin Elliott went to the father and son’s home in Winder to ask questions about a shooting threat made on the Discord platform.

The teenager denies making the online threat and says he has deleted his account on the platform.

Colin Gray told the investigator that his son was doing “really well” at school despite the stress within the family and that he kept a constant eye on him, as he said he had become a regular at his school.

During the interview, the father explained the family’s situation, saying that “one day” he ran home after a cop called to report that he was being evicted and that his belongings were outside the house in an upscale neighborhood nearby.

That, Colin Gray said, was part of a series of stressful events for his son, including bullying at school and the separation of the boy’s father and mother, with whom two of their children were staying.

“She took my youngest two and went home with her mother,” Colin Gray told the investigator. “Colt and I rented a house and came here.”

He told detectives he wanted to make sure the boy behaved well, had respect for the power and dangers of firearms, and was not harassed at the high school.

“He had a hard time in the beginning with the divorce and everything,” Colin Gray said. “He gets upset under pressure. He’s not really thinking straight. Just put your arms around him and help him through seventh grade.”

The teen told Miller he had finished seventh grade a few days early.

His father said he taught his son to hunt to discourage him from playing video games and to encourage him to seek out outdoor activities.

The comments were made in response to a question from Miller about whether Colin Gray kept guns at home and whether his then 13-year-old son had access to them.

“I mean, there’s nothing loaded,” Colin Gray said. “We actually shoot a lot. We do a lot of deer hunting. He shot his first deer this year.”

“You can see him with blood on his cheeks from shooting his first deer,” Colin Gray said as he showed the investigator a photo. “It was just the best day ever.”

If his son threatened to shoot up a school, Colin Gray said, he would be “as mad as hell, and then all the guns would go away.”

Investigators determined there was not enough evidence to link the boy to the school shooting threat forwarded by the FBI. There were no arrests or referrals to prosecutors related to that threat, according to investigative documents.

Two law enforcement sources familiar with the investigation into the school shooting said Colin Gray purchased an AR-15-style semi-automatic rifle as a gift for his son following the investigation into the 2023 threat.

Authorities have not linked that weapon to last week’s school shooting, but they did say the weapon used was based on the AR-15 platform.

Students Mason Schermerhorn and Christian Angulo, both 14, and teachers Richard Aspinwall, 39, and Cristina Irimie, 53, were killed.

Authorities said another teacher and eight other students were injured, seven of whom were hit by gunfire.

The school management has not yet set a date on which the 1,900 students should return to school.
