Colin Gray, whose 14-year-old son used an assault rifle bought as a Christmas gift to kill four people at Georgia’s Apalachee High School on September 4, 2024, was sentenced Thursday to 15 years in prison by Piedmont Circuit Superior Court Chief Judge Nicholas Primm.
Sentencing and the Legal Balance Between Father and Son
Colin Gray faced 15 years in prison after a Barrow County jury convicted him in March on charges including second-degree murder and involuntary manslaughter.
The legal proceedings unfolded just days after his son, Colt Gray—now 16 years old—was sentenced on Tuesday to life in prison without the possibility of parole. The teenager pleaded guilty without reaching a deal to 55 charges, including murder, for the September 4, 2024, massacre that claimed the lives of 14-year-old students Mason Schermerhorn and Christian Angulo, alongside teachers Richard Ricky
Aspinwall, 39, and Cristina Irimie, 53. Another teacher and eight students were also wounded in the attack.
“Mr. Gray committed crimes, but his crimes are tethered to the tragedy committed by his son, and that makes the situation a little unique.”
Chief Judge Nicholas Primm, Piedmont Circuit Superior Court
The defense had asked for a 10-year prison sentence followed by probation, with attorney Brian Hobbs arguing that a multi-decade term would amount to a de facto death sentence for the 55-year-old father and would blur the line under Georgia law between intended harm and failed prevention. Conversely, prosecutor Brad Smith urged the court to impose an 80-year prison sentence.
Ignored Warnings and the Prosecutor’s Case on Neglect
The prosecution’s argument hinged on what Colin Gray knew and what risks he chose to disregard. Investigators established that the father gifted the AR-style rifle to his son alongside ammunition, a gun sight, and other accessories just months after local law enforcement had already visited their home because the teenager had made online threats about shooting up an elementary school.
Testimony during the hearings also revealed deep friction within the household. The teenager’s mother, Marcee Gray, who was separated from Colin Gray, told investigators that she had pleaded with her estranged husband to lock up his firearms and keep them away from their son in the weeks leading up to the massacre. Instead, the weapon remained accessible in the teenager’s bedroom.

“This was the risk he was ignoring — that there would be a mass shooting of children at a school — and he gave his son the exact tool he would need to accomplish this.”
Prosecutor Brad Smith
Investigators detailed how the young shooter carried the weapon onto a school bus wrapped in poster board, later emerging from a bathroom to open fire in a hallway and a classroom. Evidence presented in court showed the teenager had grown obsessed with prior mass casualty events, including the 1999 Columbine High School shooting and the 2012 Sandy Hook Elementary School shooting, and actively sought notoriety within an online community dedicated to true crime.
Victim Impact Statements and the National Legal Precedent
The courtroom proceedings on Thursday featured emotional testimony from the families of those killed and injured, who condemned the elder Gray’s failure to act as a responsible parent and gun owner. Shayna Aspinwall, the widow of teacher and football coach Richard Aspinwall, told the court that her family had been handed a life sentence of grief and trauma.
“Parenting is hard. Parenting alone is even harder. I know that because I lived it … but there is a world of difference between struggling to parent and refusing to parent.”
Maria Schermerhorn, mother of victim Mason Schermerhorn
The case stands as one of a handful of instances in the United States where a parent has faced criminal prosecution and conviction resulting from a school shooting perpetrated by their child.
