In a case that has tested the limits of liability for a murder, both a teenager and his father were found guilty of a shooting that occurred in Georgia in 2024.

A U.S. judge sentenced Colt Gray to life imprisonment without the possibility of parole on Tuesday for killing two students and two teachers in an attack at Apalachee High School in Georgia.
The 16-year-old pleaded guilty on Friday to 55 charges, including murder, for the September 4, 2024 shooting at the school located about 73 kilometers northeast of Atlanta. The teenager, who was 14 at the time, was tried as an adult.
At the start of the hearing, Judge Nicholas Primm of the Barrow County Superior Court said his discretion was limited: by law, Gray would receive a life sentence, but it was up to the judge to determine if the youth would ever meet the requirements for parole.
On Tuesday, The New York Times wrote, Judge Primm stated that he had weighed Gray’s age and immaturity, as well as his acceptance of guilt, against the depravity of the attack. His crimes, committed in pursuit of infamy, according to the judge, placed him in an “irredeemable moral wasteland.”
“You understood the horror of what you were going to do,” Primm said. “You wrote: ‘I want to make history. I want people to remember the pain I caused.’ And you succeeded: it is unlikely that the pain you inflicted on this community will disappear in my lifetime,” he added.
The shooting—the deadliest at a school in Georgia’s history—attracted national attention because prosecutors managed to hold the father, Colin Gray, criminally responsible for the attack. Prosecutors pointed out that he allowed his son virtually unlimited access to the weapon used in the attack—a rifle of the AR-15 type that had been given to him for Christmas—and that he ignored signs of his son’s deteriorating mental health.
The sentencing hearing for the father is scheduled to begin on Thursday. Colin Gray was found guilty on Tuesday of murder and involuntary manslaughter.
The jury deliberated for less than two hours before finding him guilty of 27 charges: two counts of second-degree murder, two counts of involuntary manslaughter, 18 counts of child cruelty, and five counts of reckless conduct.
According to CNN, at the defense table, Colin Gray showed no visible reaction to the verdict. He was taken out of the courtroom in handcuffs. He faces a sentence of between 10 and 30 years in prison for each murder charge and between 1 and 10 years for each involuntary manslaughter charge.
“That man and his son are responsible for the immense suffering that occurred on September 4,” said prosecutor Patricia Brooks in her closing arguments. “Their hands are stained with blood.”
CNN noted that the trial was part of a broader initiative to hold more people accountable for a school shooting, including the attacker’s parents and the police officers who intervened. This case bore great similarity to the trials of James and Jennifer Crumbley, whose son, then 15, killed four students in 2021 at his high school in Oxford, Michigan. Both were found guilty of involuntary manslaughter and sentenced to between 10 and 15 years in prison.

However, Colin Gray’s defense argued that he was unaware of his son’s violent plans and had taken steps to get him help for his mental health issues.
The prosecution alleged that his actions constituted “criminal negligence” by “consciously ignoring a substantial and unjustifiable risk.”
After the verdict, Barrow County District Attorney Brad Smith noted that the Crumbley cases set a precedent and expressed hope that this verdict would “further advance justice.” He also dismissed concerns that Colin Gray was being punished for his son’s actions.
“This trial was about the actions, decisions, and responsibility of this defendant,” Smith said.
During the father’s trial and in the recent sentencing statement, prosecutors presented a series of witnesses and evidence describing the September 4, 2024 shooting as the culmination of years of escalating family conflict and a growing obsession with violence by young Gray.
Relatives testified at trial that long before the shooting, Colt Gray suffered violent outbursts and episodes of overwhelming anxiety. He told them he heard voices urging him to act aggressively.
Mental health experts stated, according to CNN, that he had been affected by persistent isolation and neglect during his childhood. However, they also indicated that he was faking and that the symptoms he described seemed exaggerated or very unlikely, such as hearing voices only on specific days of the week. They stated they believed he did not suffer from schizophrenia or bipolar disorder.
In a search of his home immediately after the shooting, investigators found on his bedroom wall a collage with photographs of the perpetrator of the 2018 Parkland, Florida high school shooting, who was 19 years old, and press clippings related to that shooting, in which 17 people died.
He had also left detailed plans. At the sentencing hearing, prosecutors showed stick figure drawings Gray had made in a notebook, which apparently imitated sketches of the Parkland shooter.
Last year, Georgia lawmakers passed a school safety law in response to the shooting. This law requires state officials to create an alert system that includes the names of students who, according to investigations, have threatened violence or committed violent acts in schools.
It also requires law enforcement to notify schools when they become aware that a minor has threatened to kill or injure someone at the educational center, the implementation of panic alert buttons on school mobile phones, the speeding up of record transfers when students change schools, and the designation of mental health coordinators in each of the state’s 180 school districts.
