Colin Gray was charged with criminal recklessness for allowing his 14-year-old son, Colt, access to a rifle.

The father of a US school shooter has been found guilty of second-degree murder and manslaughter after his son attacked the school apalachee high school September 4, 2024 in Winder, Georgia.

A jury in the southern state reached its verdict Tuesday after deliberating for less than two hours.

Father, Colin Graywas found guilty on all charges. His son, Colt Gray, was 14 when he opened fire at the high school he attended, killing two students and two teachers and injuring seven others.

Colin Gray’s case is the latest in which a parent faces jail for allegedly negligent negligence that led to a school shooting.

His conviction follows two guilty verdicts in 2024 against the parents of another school shooter. Jennifer and James Crumbleythey were charged with manslaughter.

Prosecutors in the Georgia case accused Gray of helping his son attack the high school by providing guns and ammunition.

The charges against Gray include two counts of second-degree murder for the deaths of 14-year-old students Mason Schermerhorn and Christian Angulo.

Georgia law allows second-degree murder charges in cases of alleged child abuse resulting in the death of a child.

Gray was also found guilty of two counts of manslaughter in the deaths of two teachers, Richard Aspinwall, 39, and Cristina Irimie, 53. He was also found guilty of reckless conduct.

Gray faces life in prison. His sentence is expected to be determined later.

However, his defense team argued that Gray should not be held responsible for the actions of his teenage son, who made the decision alone to commit a school shooting.

His attorney also described Gray as a struggling single father caring for three children.

Gray himself testified that before the shooting, he did not believe his son was capable of such violence.

Asked about his son’s mental health, he told the court: “I could have done better.”

But the father denied seeing the warning signs before the shooting, explaining that he had told his son that the gun was only for outings at the shooting range or hunting.

Gray had pleaded not guilty before Tuesday’s conviction.

But prosecutors argued that Gray ignored red flags before the attack, including his son’s growing fascination with past school shootings.

They argued that as a father, Gray had a responsibility to keep guns away from his son and prevent harm, especially when his son was facing mental health challenges.

“We talk a lot about our state’s rights,” Barrow County District Attorney Brad Smith said after the verdict.

“But God has given us a responsibility to protect our children, and I hope we remember, as parents, as community members, to protect our children because that is our God-given responsibility.”

Colt Gray’s mother, Marcie Gray, also testified in court that she urged Colin Gray to take away the teen’s gun before the shooting.

She and Colin Gray were separated at the time and she was not charged in connection with the attack.

Gray reportedly gave his son a semi-automatic AR-15-style rifle for Christmas. Shortly before Colt Gray opened fire at Apalachee High School, the 14-year-old boy texted his father, “I’m sorry, it’s not your fault.” He also texted his mother to apologize.

Colt Gray faces 55 counts in a separate criminal trial, including malice murder and felony murder. He pleads not guilty.
