- Investigators say Gray knew of his son’s fixation on school shooters, including a shrine to the Parkland gunman, and had recently sought counseling over the teen’s anger and volatility.
- The trial is being held in Barrow County with jurors selected in neighboring Hall County after venue concerns, with about three weeks reserved for selection and testimony.
- The attack killed teachers Richard Aspinwall and Cristina Irimie and students Mason Schermerhorn and Christian Angulo, injured nine others, and led to 55 felony counts against Colt Gray as an adult with no trial date set.
