Colt Gray, the 14-year-old accused of opening fire at his Georgia high school, 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 Apalachee High School.
Seven students and two teachers were injured in Wednesday morning’s shooting, officials said. All of the injured victims are expected to make full recoveries, Barrow County Sheriff Jud Smith said.
Gray has been charged with four counts of felony murder, with additional charges expected, the GBI said. He will be tried as an adult, authorities said.
Gray, who allegedly used an AR-platform-style weapon, surrendered at the scene to the school resource officers, according to the GBI.
A motive has not yet been determined and it is unknown if the victims were targeted, investigators said.
Gray’s aunt, Annie Brown, said her nephew was “begging for help from everybody around him.”
The teen’s father, Colin Gray, 54, was arrested Thursday and charged with four counts of involuntary manslaughter, two counts of second-degree murder and eight counts of cruelty to children, the GBI said.
Colin Gray is accused of “knowingly allowing his son, Colt, to possess a weapon,” GBI Director Chris Hosey said Thursday.
It is not yet clear when Colin Gray is expected to appear in court or whether he has obtained legal counsel.
