Colin Gray, 54, the father of Apalachee High School shooting suspect Colt Gray, 14, enters the Barrow County courthouse for his first appearance, on September 6, 2024, in Winder, Georgia. Colin Gray, 56, admitted to providing the assault rifle used by his then-14-year-old son in the September 2024 shooting at Apalachee High School, which killed two students and two teachers. Colin Gray marks the latest parent charged and convicted in the U.S. in connection with a mass shooting carried out by his child. Several other parents have been convicted in the U.S. in connection with a mass shooting carried out by their children. In 2024, Jennifer and James Crumbley were convicted of charges stemming from a deadly mass shooting at a Michigan high school committed by their then-15-year-old son, Ethan Crumbley.
