The mother of the 14-year-old suspect in a fatal Georgia high school shooting was arrested on domestic violence charges last year, court records show, the latest indication that the teen accused of four counts of murder had a turbulent home life.

According to Barrow County court records, Colt Gray’s mother, Marcee Gray, pleaded guilty in December to second-degree criminal damage and trespassing/domestic violence.

She also had warrants for her arrest stemming from a November 2023 incident in which drugs, including methamphetamine and fentanyl, were found in her car, according to arrest warrants obtained by NBC News.

Those details came to light Friday after the suspect’s father, Colin Gray, was arrested on charges of allowing his son to own a gun. The 54-year-old had given his son an AR-15-style rifle, two law enforcement sources familiar with the investigation say.

Father and son appeared in court for the first time on Friday.

The son is accused of shooting two students and two teachers on his first full day of school at Apalachee High School, where he was new, authorities said.

His father faces 14 charges, including manslaughter, first-degree murder and child abuse. If convicted on all counts, he faces up to 180 years in prison.

The students who died in the shooting on Wednesday were 14-year-olds Mason Schermerhorn and Christian Angulo. Mathematics teachers Richard Aspinwall (39) and Cristina Irimie (53) were also killed.

At the suspected shooter’s last school, he was taunted so often that he asked to change school districts, his father said, according to transcripts of an interview he conducted with the Jackson County Sheriff’s Office in May 2023, because his son had threatened online to carry out a shooting spree at the school.

Court records show the teenager was not arrested after the interview last year because he could not be linked to the online account from which the threats were made.

He had shown interest in previous mass shootings, particularly the 2018 massacre at Marjory Stoneman Douglas High School in Parkland, Florida, according to two senior law enforcement officials briefed on the investigation. The information came as a result of searches conducted as part of the shooting investigation.

According to the records, the teenager was experiencing problems at home after his parents separated and his family was evicted from their home, separating him from his two younger siblings.

“He’s been through a lot,” Colin Gray told a Jackson County Sheriff’s investigator in May 2023 when his son was being investigated on threatening charges.

In two interviews with the Inquirer last year, Colin Gray acknowledged that his son was struggling to cope with challenges at home and at school, but he expressed no concern that his son might commit a massacre.

Colin Gray said his son denied the threats and said he did not want to be “involved in any of this”.

“He said, ‘I’m a good boy, Dad. I would never do something like that,'” the father told the investigator. “I feel sorry for him because all this happened.”

Colin Gray said his son was “teased” and physically tormented by his classmates in his last middle school. The apparent bullying prompted the father, out of his own frustration, to speak to school administrators several times.

“I don’t want him to fight anybody, but they just keep pinching and touching him,” he said, according to the transcript. “Words are one thing, but when you start touching him, that’s a whole different thing.”

Colin Gray said the conflict had “escalated.” He said his son, who gets “nervous” under pressure, was unable to concentrate on his final exams and said he wanted to move out of the school district.

“He should be excited about starting eighth grade,” his father said. “It was just very difficult for him to go to school.”

In response to questions from the investigator, Colin Gray said he had guns at home that his son had access to, but that they were not loaded.

Colin Gray said he would have been “furious” and taken away all his weapons if he had found out that his son had actually made the online threats.

The father said he introduced his son to bow hunting and later introduced him to firearms.

He said his son shot his first deer in 2023. He has a photo of that moment showing the boy with blood on his cheeks.

Colin Gray said his son’s mother was involved in “a lot of crap.”

According to records, after being charged with domestic violence, Marcee Gray was ordered to have no further contact with Colin Gray, except through third parties and in matters involving the children or a divorce.

Marcee Gray was not immediately available for comment.
