Teen suspect in Georgia school shooting expected to be charged with murder, tried as adult

The Georgia Bureau of Investigation identified the victims of the Apalachee High School mass shooting as Richard Aspinwall and Christina Irimie, who were math teachers, and 14-year-old students Mason Schermerhorn and Christian Angulo.

Aspinwall was also a football coach.

Law enforcement has identified the suspect as 14-year-old Colt Gray, a student at the high school. He is in custody and expected to be charged Thursday with murder and tried as an adult, according to ABC News. 

The alleged shooter was reportedly interviewed by the FBI previously due to threats he made online but no arrest was made.
