Colin Gray is on trial in Georgia for giving his teenage son Colt Gray the assault rifle he allegedly used to kill four people at his high school in 2024. Colin says he did, and could not know his son was planning an attack at the school. Now, Colt’s mother Marcee Gray, who is estranged from Colin, is taking the stand. Marcee testified that their son’s behavior leading up to the shooting was “alarming." Colt Gray is being charged as an adult, and a date for his trial has not yet been set.
