An Atlanta judge set a plea and sentencing hearing later this month for a teenager accused of killing four people in a September 2024 shooting at Appalachee High School, located about 30 miles west of Athens.
Colt Gray, 16, had pleaded not guilty to charges including murder in the shooting that killed two students and two teachers, and left several others wounded, at the high school.
In a court filing Friday, the judge overseeing his case set a "Non-Negotiated Plea and Sentencing Hearing" to begin July 24. The judge had previously said that if Gray wanted to plead guilty ahead of trial, he must notify the state and court by this coming Wednesday.
A non-negotiated plea means that the state and the defense have not reached an agreement on a sentence. Unlike a negotiated plea, or plea deal, where a defendant reaches an agreement with prosecutors to plead guilty in exchange for an agreed upon sentence and possibly reduced charges, this leaves sentencing entirely up to the judge who makes a decision after giving each side a chance to present a summary of the case and a sentencing recommendation.
Colt Gray's attorney did not immediately respond to an email seeking comment Sunday.
Gray's trial had been set to begin in mid-October in Columbia County, about 100 miles from Barrow County where the shooting happened, after the judge agreed to a defense request to change the venue.
Gray's father, Colin Gray, was convicted by a jury in March on charges including second-degree murder and involuntary manslaughter after prosecutors said he gave his teenage son the assault-style rifle used to open fire at the school. The elder Gray is set to be sentenced later this month.
The Sept. 4, 2024, shooting killed teachers Richard "Ricky" Aspinwall, 39, and Cristina Irimie, 53, and students Mason Schermerhorn and Christian Angulo, both 14. Another teacher and eight more students were wounded, seven of them hit by gunfire. Colt Gray, who was 14 at the time of the shooting, was charged as an adult with 55 total counts, including murder, cruelty to children and 25 counts of aggravated assault.
Investigators testified that Colt Gray carried the rifle given to him by his father onto the school bus with the barrel wrapped in a poster board. They said the teenager left his second-period class and emerged from a bathroom with the rifle, shooting people in a classroom and hallway.
Investigators have said the teenager carefully plotted the shooting at the high school of 1,900 students. A Georgia Bureau of Investigation agent testified that the boy left a notebook in his classroom with step-by-step instructions and a diagram to prepare for the assault, including an estimate that he could kill as many as 26 people and wound as many as 13 others.
