Georgia high school shooting suspect set to face judge for his arraignment

Colt Gray, the 14-year-old suspect in the Apalachee High School shooting, is set to face a judge Friday for his arraignment.

This will mark the first court appearance for the teenager, who authorities allege killed four people, including two teachers and two students, at his high school and injured nine others. The Georgia Bureau of Investigations previously said he will be tried as an adult.

He has been charged with four counts of felony murder, with additional charges expected, the GBI said. Gray surrendered at the scene to the school resource officers, according to the GBI.

He was taken into custody on Wednesday at 10:30 a.m. ET, seven minutes after the initial service call went out, according to the Barrow County Sheriff's Office, which employs the school resource officers.

On Thursday night, Colin Gray, the father of the 14-year-old, was arrested and charged with murder in connection with the deadly shooting, the GBI said.

Colin Gray, 54, was charged with four counts of involuntary manslaughter, two counts of second-degree murder and eight counts of cruelty to children, the GBI said.

At a news conference on Thursday evening, Chris Hosey, director of the GBI said that the father was arrested for "knowingly allowing his son, Colt, to possess a weapon."

It is currently unclear when Colin Gray is expected to appear in court or whether he has obtained legal counsel following his arrest.
