After four people were shot and killed at Apalachee High School in Georgia in September, many people believe officials failed to see warning signs that the 14-year-old accused of the shooting was displaying.

A 14-year-old is accused of bringing a gun to Apalachee High School, months after a mass shooting left four people dead, Georgia authorities said. The student was arrested just after 2 p.m. Wednesday, Jan. 8, at the school in Winder, the Barrow County Sheriff’s Office said in a news release.

Fears over unmonitored doors, crowded hallways and a lack of escape routes. That’s how Apalachee High School junior Sasha Contreras described Monday’s return to classes before the Barrow County school board members Tuesday.
