Colt Gray’s father has been convicted in connection with the school shooting that left four people dead and nine others wounded.
Colin Gray had entered not-guilty pleas to the charges brought against him after the 2024 attack in Georgia.
The victims of the September 4 shooting at Apalachee High School in Winder, Barrow County, were students Mason Schermerhorn and Christian Angulo, along with teachers Christina Irimie and Richard Aspinwall.
Nine additional people were injured during the incident.
At the time, 14-year-old Colt Gray was taken into custody after surrendering to police. He remains in detention while awaiting his own trial.
Colin Gray was later arrested and indicted on 27 counts: two counts of second-degree murder, two counts of involuntary manslaughter, 18 counts of cruelty to children, and five counts of reckless conduct.
A jury has now found him guilty on every charge. Sentencing guidelines cited in court indicate he could face 10 to 30 years in prison for each murder count, and 1 to 10 years for each manslaughter count.
Prosecutors argued that Gray purchased an AR-15-style rifle for his son as a Christmas gift and that the teen was able to access both the gun and ammunition.
They also alleged he did so despite warnings that his son posed a danger to others.
Earlier disclosures in the case said the teenager was interviewed by the FBI in May 2023 after anonymous reports claimed someone had made ‘online threats to commit a school shooting at an unidentified location and time’.
Colt Gray and his father were both questioned, though the teen denied making any threats and was not arrested then.
The FBI said in a statement: “The father stated that he had hunting guns in the house, but the subject did not have unsupervised access to them […] At the time, there was no probable cause for an arrest or to take any additional law enforcement action on the local, state or federal levels.”
During the trial, Barrow County Assistant District Attorney Patricia Brooks told jurors: “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,”
As she delivered her closing remarks, Brooks added: “That man and his son are both responsible for the immense suffering that occurred on September 4,
“The blood is on their hands.”
