Questions surround weapon, motive in deadly Georgia high school shooting
Four were killed in the shooting at Apalachee High School in Winder, Georgia.
As investigators work to determine a motive behind Wednesday's deadly shooting at Apalachee High School in Winder, Georgia, they said they're also seeking answers about the weapon allegedly used by the 14-year-old suspect.
Two teachers and two students were killed: math teacher and football coach Richard Aspinwall, 39; math teacher Christina Irimie, 53; and students Mason Schermerhorn, 14, and Christian Angulo, 14, officials said.
Eight students and one teacher were injured, officials said. All of the injured victims are expected to recover, Barrow County Sheriff Jud Smith said.

The 14-year-old suspect, Colt Gray, a student at the school, surrendered at the scene and was taken into custody, the GBI said. He will be charged with murder and tried as an adult, the GBI said.
He was being held Thursday morning at Gainesville Regional Youth Detention Center, the Department of Juvenile Justice told Atlanta ABC affiliate WSB.

An AR-platform-style weapon was used in the shooting, according to GBI Director Chris Hosey.
Officials said they did not yet have any answers for how Gray was allegedly able to obtain the gun and get it into the school. Gray was interviewed by investigators and GBI, but Smith did not disclose further details.
A motive has not yet been determined and it is unknown if the victims were targeted, investigators said.

Last year, the Jackson County, Georgia, Sheriff's Office, acting on an alert, interviewed the alleged shooting suspect, the FBI said.
"In May 2023, the FBI's National Threat Operations Center received several anonymous tips about online threats to commit a school shooting at an unidentified location and time," the FBI said. "Within 24 hours, the FBI determined the online post originated in Georgia and the FBI's Atlanta Field Office referred the information to the Jackson County Sheriff's Office for action."
