A jury in Winder, Georgia, convicted Colin Gray on Tuesday of second-degree murder and involuntary manslaughter in connection with the September 2024 shooting at Apalachee High School in Winder, northeast of Atlanta.
Prosecutors argued Gray gave his teenage son the gun the teen is accused of using in the attack. Jurors deliberated for less than two hours before finding Gray guilty of all charges.
Gray was convicted of second-degree murder in the deaths of two 14-year-old students, Mason Schermerhorn and Christian Angulo. Under Georgia law, second-degree murder is defined as causing the death of a child by committing the crime of cruelty to children. He was also convicted of involuntary manslaughter in the deaths of teachers Richard Aspinwall, 39, and Cristina Irimie, 53.
Another teacher and eight students were wounded. Gray was additionally convicted on multiple counts of reckless conduct and cruelty to children.
