Georgia School Shooter Hid AR-15 in Backpack, Killed Four

14-year-old Colt Gray brought the gun to school, evaded detection, and began the deadly attack after leaving his classroom.

Colt Gray, 14, concealed an assault rifle in his backpack and rode the school bus to Apalachee High School.
Gray left his second-period class under the pretense of visiting the front office but hid in a bathroom before starting the shooting.
The attack resulted in the deaths of two students and two teachers, with nine others injured.
Gray's father, Colin Gray, faces multiple charges for allegedly giving his son access to the firearm used in the attack.
Authorities and school officials are under scrutiny for failing to act on prior warnings about Gray's behavior and online threats.
