The latest on the Georgia high school shooting

Two 14-year-old students and two teachers were killed yesterday in a mass shooting at Apalachee High School in Winder, Georgia. Nine other people — eight students and one teacher — were wounded and hospitalized, all of whom are expected to survive.

The suspect, a 14-year-old student at the school, and his father were questioned by law enforcement last year regarding online threats to commit a school shooting.

The gun used in Wednesday’s shooting was an AR-platform weapon, according to the director of the Georgia Bureau of Investigation. A law enforcement official told CNN it was an AR-15-style rifle. Authorities are investigating how the suspect brought the weapon into the school.

The suspect will be charged with murder and tried as an adult, according to the Georgia Bureau of Investigation. He will make his first court appearance on Friday, a Georgia Department of Juvenile Justice spokesperson said.
