Barrow County Superior Court Judge Currie Mingledorff told the teen he could get life in prison if convicted -- the maximum sentence due to Gray's age. For adults, the death penalty would have been possible.
With victims' families in the courtroom, Colt Gray appeared briefly in handcuffs and chains wearing a green shirt and tan pants.
Judge Mingledorff told Colin Gray he could get 30 years in prison for each second-degree murder count and up to 10 years on the involuntary manslaughter counts. He also faces up to 10 years on each of eight counts of cruelty to children.
The defendants did not enter pleas and they did not request bond during the hearings.
