A Georgia grand jury indicted a father and son on murder and other charges Thursday in the mass shooting at Apalachee High School in Winder, Georgia, last month that left four people dead and another nine injured.

The attack on Apalachee High School, which the father and son have been indicted for claimed four lives and wounded multiple others.

A grand jury handed down dozens of charges Thursday for the alleged Apalachee High School shooter and his father, also accused in connection with the deadliest school shooting in Georgia's history.
