Colin Gray, father of 14-year-old Colt Gray who carried out a deadly school shooting in Georgia, was sentenced to 15 years in prison on July 30, 2026, for second-degree murder, involuntary manslaughter, and related charges [1, 2, 3, 4, 5, 6, 7, 8].

The shooting occurred in September 2024 at Apalachee High School in Winder, Georgia. Colt Gray used an AR-15 style rifle to kill two students aged 14 and two teachers, injuring nine others [1, 2, 3, 4, 5, 6, 7, 8]. Prosecutors said Colin Gray gave the firearm to his son as a Christmas gift in December 2023, despite warnings about Colt’s mental instability and potential threat [1, 2, 3, 4, 5, 6, 7, 8].

Judge Nicholas Primm said at sentencing, "It is clear you failed as a parent. You were convicted because the warning lights were flashing brighter and brighter and you didn’t get him help and you didn’t remove his access to the guns" [6]. He added in court, "身為父母，你失職了" (As a parent, you failed) [2].

Prosecutor Brad Smith said, "If Colin Gray had simply taken the rifle away, this tragedy could have been prevented. He ignored the risk of a mass shooting at school" [7]. The prosecution had sought an 80-year sentence, but the judge imposed 15 years after combining charges [2, 3, 7].

Colt Gray was sentenced a day earlier, July 28, 2026, to life imprisonment without parole for murder and related offenses [1, 2, 3, 4, 5, 6, 7, 8]. The teenager had shown signs of mental decline and participated in online communities focused on mass shootings in the weeks before the attack [2, 3]. During the shooting, he concealed the rifle with cardboard to bring it on the school bus and fired in hallways and classrooms [2, 3].

Colin and Colt Gray are separated from Colt’s mother, who had asked Colin to secure the firearms before the shooting [2, 3]. This case is rare in the US due to the father's conviction for his role in enabling the school shooting, similar to the 2021 Oxford High School shooting where parents were sentenced for involuntary manslaughter [1, 2, 3, 6, 7, 8].

The 15-year prison term for Colin Gray marks a significant judicial outcome holding parents legally accountable for gun access in school shootings.
