WINDER, Ga. (Atlanta News First) — Colin Gray may be facing a long prison sentence, but his son —charged with actually carrying out the Sept. 4, 2024, deadly mass Georgia school shooting — hasn’t stood trial yet.

Colt Gray has been charged with 55 counts in connection with the mass shooting at Apalachee High School in Barrow County, Georgia. His father was convicted on Tuesday on two counts of murder in the second degree, two counts of involuntary manslaughter, five counts of reckless conduct and 20 counts of cruelty to children in the second degree.

Colt Gray’s last court appearance was in December 2024, where his attorneys said the teen was undergoing medical evaluations. Judge Nicholas Primm, who has presided over the case since its inception, has set an April 1, 2026, deadline for all motions to be filed in his case.

Colt Gray is facing four counts of murder, four counts of felony murder, four counts of aggravated battery, 25 counts of aggravated assault and 18 counts of cruelty to children in the first degree. Like his father, he has pleaded not guilty.

Colin Gray was convicted by a jury after less than two hours of deliberations on more than 25 felony counts related to the shooting.

He is facing a maximum of 180 years in prison after being accused of allowing his son access to the AR-style rifle recovered after the shooting, as well as a variety of ammunition and accessories recovered at the crime scene and at his residence.

Colin Gray had no reaction when the verdicts were read. The parents of Mason Schermerhorn, one of those killed in the shooting, were sobbing in the courtroom, while the father of another victim, Christian Angulo, was also emotional.

Teachers Richard Aspinwall and Cristina Irimie were also killed during the shooting.

Brad Smith, district attorney for the Piedmont Judicial Circuit, said “the state stands ready to try the case” of Colt Gray.

Jurors heard two weeks of emotional testimony and graphic photos, videos and details of the shooting, with Colin Gray himself taking the stand on the final day of witness testimony.

Prosecutors said Colin Gray knowingly allowed Colt Gray access to firearms despite his knowledge of his son’s unstable mental and emotional condition. They rested their case after showing surveillance video of Colt Gray allegedly carrying out the school shooting.

Colin Gray and at least one juror were visibly weeping as the footage was shown.

Colin Gray was the only witness called by his defense attorneys.

Colin Gray’s trial was the nation’s second judicial case against the parents of an alleged school shooter.

Jennifer and James Crumbley were the first parents ever convicted in a U.S. mass school shooting case. Their son, Ethan Crumbley, 15, killed four students and wounded seven others at Oxford High School in November 2021.

Both were convicted of four counts of involuntary manslaughter, one for each victim killed, and each was sentenced to 10 to 15 years in prison in April 2024.
