His father, Colin Gray, was indicted on 29 counts, including second-degree murder, second-degree cruelty to children, involuntary manslaughter and reckless conduct, according to records from the Barrow County District Attorney's Office.
The father and son were indicted separately.
Two law enforcement sources familiar with the investigation told NBC News last month that Gray gave his son an AR-15 style rifle as a gift.

Gray gave his son the weapon at some point after they were interviewed by law enforcement officials in May 2023 in connection with reported online threats to carry out a school shooting, the sources said.
Both are scheduled to appear for arraignment on Nov. 21, when each would formally enter a plea. Colin Gray is being held in the Barrow County jail and his son is being held in a juvenile detention center in Gainesville.
Barrow County District Attorney Brad Smith said last month Colin Gray's charges marked the first time in state history a parent of a suspected school shooter was charged.
Killed in the shooting were Mason Schermerhorn, 14; Christian Angulo, 14; Richard Aspinwall, 39; Cristina Irimie, 53.
