The 14-year-old suspect in a shooting that killed four people at a Georgia high school and his father, who was arrested for allowing his son to have a weapon, will stay in custody after their lawyers decided not to seek bail Friday.

Colt Gray, who has been charged with four counts of murder, is accused of using a semiautomatic assault-style rifle to kill two fellow students and two teachers Wednesday at Apalachee High School in Winder, outside Atlanta. His father, Colin Gray, faces related charges in the latest attempt by prosecutors to hold parents responsible for their children’s actions in school shootings.

“You don’t have to have been physically injured in this to be a victim,” District Attorney Brad Smith said outside the Barrow County courthouse. “Everyone in this community is a victim. Every child in that school was a victim.”

The father and son appeared in back-to-back hearings Friday morning with about 50 onlookers in the courtroom, where workers had placed boxes of tissues along the benches, in addition to members of the media and sheriff’s deputies. Some victims’ family members in the front row hugged each other and one woman clutched a stuffed animal.

During his hearing, Colt Gray, wearing khaki pants and a green shirt, was advised of his rights as well as the charges and penalties he faced for the shooting at the school where he was a student. He was escorted out in shackles at the wrists and ankles.

The judge then called the teen back to the courtroom to correct an earlier misstatement that his crimes could be punishable by death. Because he’s a juvenile, the maximum penalty he would face is life without parole.

Shortly afterward, Colin Gray was brought into court dressed in a gray-striped jail uniform. Colin Gray, 54, was charged Thursday in connection with the shooting and answered questions in a barely audible croak, giving his age and saying he finished 11th grade, earning a high school equivalency diploma.

Colin Gray has been charged with involuntary manslaughter and second-degree murder related to the shooting. Arrest warrants said he caused the deaths of others “by providing a firearm to Colt Gray with knowledge that he was threat to himself and others.”

The charges come five months after Michigan parents Jennifer and James Crumbley were the first convicted in a U.S. mass school shooting. They were sentenced to at least 10 years in prison for not securing a firearm at home and acting indifferently to signs of their son’s deteriorating mental health before he killed four students in 2021. The Georgia shootings have also renewed debate about safe storage laws for guns and have parents wondering how to talk to their children about school shootings and trauma.

The hearings for the father and son came as police in the Atlanta suburb of Dunwoody said schools there and nationwide have received threats of violence since the Apalachee High School shooting, police said in a statement. The Georgia Bureau of Investigation also noted that numerous threats have been made to schools across the state this week.
