They accuse the father of the teenager suspected of the shooting at a school in Georgia of murder.

The Georgia Bureau of Investigations (GBI) arrested and charged 54-year-old Colin Gray with murder; he is the father of the teenager suspected in the shooting at Apalachee High School in the city of Winder.

Gray faces multiple charges, including involuntary manslaughter, second-degree murder, and cruelty to minors, in connection with the incident involving his son Colt, who allegedly used a rifle that Colin gifted him for Christmas.

In coordination with district attorney Brad Smith, the GBI disclosed the charges on the social media platform X, and the father faces up to 180 years in prison. His next hearing will be on December 4.

The 14-year-old teenager was identified as the alleged attacker at the school and "will be charged with murder and tried as an adult," Chris Hosey, director of the Georgia Bureau of Investigations, told CNN.

The third-year student at Apalachee High School, Lyela Sayarath, told CNN that she shared classes with the alleged shooter and that he left the classroom at the beginning of her Algebra 1 class.

Upon returning, near the end of the class, he knocked on the door to come back in. However, another student noticed that he was carrying a weapon when going to open the door, so they did not let him in.

Then it was when he went to the next classroom and opened fire with an AR-15 style rifle, leaving two teachers and the same number of students dead.

The victims were identified as Richard Aspinwall and Christina Irimie, both math teachers; as well as students Mason Schermerhorn and Christian Angulo, both 14 years old.

There were also injuries, but it is expected that those hospitalized "will fully recover," said Barrow County Sheriff Jud Smith at a press conference on Wednesday night.

The investigation into this unfortunate event is still ongoing. However, in a joint statement from the Atlanta FBI and the Jackson County Sheriff’s Office, they admitted that the alleged shooter was questioned by authorities last year in connection with "several anonymous tips about online threats to commit a shooting at a school at an unidentified location and time," but they did not have enough evidence for his arrest, they added.
