Many questions in last week’s Georgia school shooting are still unanswered, including how the suspect brought a semiautomatic assault rifle to the campus of Apalachee High School and what may have motivated the violence.

The shooting Wednesday in Winder, northeast of Atlanta, killed two teachers and two students. Another teacher and eight more students were wounded, with seven of those hit by gunfire.

Colt Gray, 14, is charged as an adult with four counts of murder, and District Attorney Brad Smith has said more charges are likely to be filed against him in connection with the wounded. Authorities have also charged his father, Colin Gray, alleging that he gave his son access to the gun when he knew or should have known that the teen was a danger to himself and others.
