In the aftermath of the bloodshed on Wednesday at Apalachee High School in Winder, Georgia, state authorities arrested Colin Gray, whose 14-year-old son, Colt Gray, allegedly shot four people to death and injured nine others before surrendering to police. The father is charged with four counts of involuntary manslaughter, eight counts of cruelty to children—and, most significantly, two counts of second-degree murder. The murder charges are unprecedented, the most severe ever filed against the parent of a school shooter.
