Colin Gray, the father of Apalachee High School shooter Colt Gray, was sentenced Thursday to 15 years in prison after a Georgia judge said he "failed as a parent" by ignoring escalating warning signs before the 2024 school massacre. "It is clear you failed as a parent," Primm said before handing down the sentence. She argued that while Colin Gray did not pull the trigger, his failure as a parent and gun owner helped make the tragedy possible. The shooting at Apalachee High School in Barrow County killed teachers Aspinwall, 39, and Cristina Irimie, 53, along with students Mason Schermerhorn and Christian Angulo, both 14. Before accepting the plea, Judge Primm questioned the teen to ensure he understood the consequences, with Gray responding, "Yes, your honor," to each question.
