July 28 (UPI) -- A 16-year-old who used an assault-style rifle to kill two other students and two teachers at his Georgia high school will spend the rest of his life in prison.

On Tuesday, a judge sentenced Colt Gray to life without parole for the Sept. 4, 2024, shooting at Apalachee High School in Winder, Georgia. Another teacher and eight other students were injured in the shooting.

Gray pleaded guilty to all 55 counts, including those of murder, on Friday.

"You do not seem to be tormented by what you did, you seemto relish following in the footsteps of the murderers you idolize," Judge Nicholas Primm of Barrow County Superior Court told Gray on Tuesday. "You aren't rackedwith guilt. You're proud of yourself."
