(NEW YORK) — The father of a Georgia teenager who carried out a deadly mass shooting at his high school was sentenced to 15 years in prison for second-degree murder and other charges after a jury found him criminally culpable for the attack. Colin Gray is the latest parent to be charged and convicted in the U.S. in connection with a mass shooting carried out by their child. Judge Primm noted the novelty of the school shooting case, saying it’s the first of its kind in Georgia and the second he’s aware of in the nation. Several of the family members of those killed in the school shooting addressed the court on Thursday, speaking to the pain they continue to endure. Several other parents have been convicted in the U.S. in connection with a mass shooting carried out by their children.
