Colin Gray, the father of Colt Gray—who carried out the September 2024 Apalachee High School shooting in Georgia—was sentenced to 15 years in prison on Thursday. Prosecutors and the court found that Colin Gray provided the assault-style semiautomatic rifle and ammunition that the teenager used during the attack, and that he failed to act as his son’s mental health worsened. Sources report that Colin Gray admitted his role in supplying the weapon used in the shooting. The sentencing hearing included arguments that he ignored warning signs and bore responsibility for the violence that resulted. Court proceedings referenced the impact of the earlier determination that Colt Gray was responsible for the deaths of four people at the school—two students and two teachers. Colt Gray was sentenced separately to life in prison without the possibility of parole after pleading guilty to murder and other charges, according to reporting. BBC coverage also quotes the judge telling Colin Gray that it was clear he failed as a parent. The outlets agree on the 15-year prison term and the central allegation that the father’s actions contributed to the gun being available to the teen.
