The conviction of the Georgia school shooter’s father is not the first time a parent has been found responsible for a mass shooting committed by their child. Nor is it likely to be the last.

A Georgia father has been found guilty in connection with the deadly shooting at Apalachee High School, marking a historic first for the state. A jury convicted Colin Gray, father of school shooting suspect, of second-degree murder and multiple additional charges after just a few hours of deliberation following two weeks of testimony.

Prosecutors say a Georgia father could have stopped his 14-year-old son from carrying out a school shooting, and they want jurors to convict him.

But Colt Gray, the shooter accused of killing Ricky Aspinwall, Cristina Irimie, Christian Angulo and Mason Schermerhorn, has not stood trial. Sheriff Smith says the community will not have justice and closure until that happens. “The job’s not done, and we’re not going to stop,” he said.

Closing arguments began early Monday afternoon in the trial of Colin Gray, the Barrow County father accused of enabling the weapon access that prosecutors say led to a deadly mass shooting.
