A Georgia father has been sentenced to 15 years in prison on murder and manslaughter charges connected to the 2024 mass shooting at Apalachee High School that left four people dead, marking only the third time a U.S. parent has faced criminal conviction for their child’s act of mass gun violence.
Fifty-five-year-old Colin Gray was found guilty by a jury in March on multiple charges stemming from the attack in Winder, a small community outside Atlanta. His 16-year-old son, Colt Gray, pleaded guilty to committing the murders last week. Investigations have confirmed that the AR-style rifle the teenager used to carry out the shooting was a Christmas gift from his father, purchased just one year before the attack.
The four victims of the shooting included two 14-year-old students, Christian Angulo and Mason Schermerhorn, and two teachers, 39-year-old Richard Aspinwall and 53-year-old Cristina Irimie. Four innocent lives were cut short in what remains one of the most high-profile school shooting cases in recent U.S. history.
Prosecutors argued during the trial that Colin Gray was the single person with the power to stop the attack from ever happening. They laid out extensive evidence that Gray ignored multiple clear warning signs about his son’s mental state and violent intentions: just seven months before the shooting, local police had questioned the teenager over online threats to carry out a school attack. Gray also failed to address notes in his son’s notebook that explicitly detailed plans to kill students and staff at the high school. Despite these red flags, Gray not only refused to secure his firearms in a locked storage container but gifted his son a military-style assault weapon.
“After seeing sign after sign of his son’s deteriorating mental state, his violence, his school-shooter obsession, the defendant had sufficient warning that his son was a bomb just waiting to go off,” Barrow County Assistant District Attorney Patricia Brooks told the jury during closing arguments. “And instead of disarming him, he gave him the detonator.”
Defense lawyers for Colin Gray attempted to shift full responsibility to the teenage shooter, arguing that the boy made a deliberate, secret decision to carry out the attack that his father could not have foreseen. “This is the person who went into the high school and shot and killed four people he didn’t even know and injured scores of others,” defense attorney Jimmy Barry told jurors. “This is the person who needs to be punished. He made a conscious decision to do this — a secretive decision.”
Prosecutors had requested the maximum possible sentence of 80 years in prison, while the defense pushed for a reduced 10-year sentence. On Thursday, Judge Nicholas Primm handed down a concurrent 15-year sentence, delivering a sharp rebuke of Gray’s failure as a parent before announcing the punishment.
“It is clear you failed as a parent,” Judge Primm stated. “The warning lights were flashing brighter and brighter…and you failed to do the simplest things to prevent this.” The judge did acknowledge a key mitigating factor, however: that Gray never intended to harm anyone and did not personally pull the trigger during the attack.
According to CBS News, this conviction is only the third time a U.S. parent has been held criminally liable for a mass shooting committed by their child. Legal precedents for holding parents accountable in such cases are very new, with the first major conviction coming earlier this year in Michigan. In that April 2024 case, the parents of a Michigan teen who killed four students were sentenced for their role in the attack — after they bought the gun their son used just days before the shooting, marking the first time a U.S. parent was convicted on criminal charges stemming from their child’s mass shooting.
