A Georgia high school teacher has been released from the hospital more than a week after he was injured in a deadly school shooting.

On the morning of September 4, a student rode the bus to his Georgia school with a rifle and knife hidden in his backpack, investigators said.

Georgia's state school superintendent says he wants the state to spend more money to guarantee security officers and wearable panic alert buttons after a school shooting killed four at Apalachee High School outside Atlanta.
