Opening statements held in the trial of a Georgia high school shooting suspect's father

A man whose teenage son is accused of killing two students and two teachers at a Georgia high school should be held responsible for providing the weapon despite warnings about alleged threats his son made, a prosecutor said Monday.

The trial of Colin Gray began Monday in one of several cases around the country where prosecutors are trying to hold parents responsible after their children are accused in fatal shootings.

Gray faces 29 counts, including two counts of second-degree murder, two counts of involuntary manslaughter and numerous counts of second-degree cruelty to children related to the September 2024 shooting at Apalachee High School in Winder.

''This is not a case about holding parents accountable for what their children do," Barrow County District Attorney Brad Smith said in his opening statement. ''This case is about this defendant and his actions in allowing a child that he has custody over access to a firearm and ammunition after being warned that that child was going to harm others.''

Prosecutors argue that amounts to cruelty to children, and second-degree murder is defined in Georgia law as causing the death of a child by committing the crime of cruelty to children.

Investigators have said Colt Gray, who was 14 at the time, carefully planned the Sept. 4, 2024, shooting at the school northeast of Atlanta that is attended by 1,900 students.

But Brian Hobbs, an attorney for Colin Gray, said the shooting's planning and timing "were hidden by Colt Gray from his father. That's the difference between tragedy and criminal liability. You cannot hold someone criminally responsible for failing to predict what was intentionally hidden from them.''

Smith told the jury that Colin Gray's daughter was in lockdown at her middle school and texted her father that there had been a shooting at the high school. When law enforcement arrived at Gray's home, he met them in the garage and ''without any prompting, he blurts out, ‘I knew it,''' Smith said.

Smith said that in September 2021, Colt Gray used a school computer to search the phrase, ''how to kill your dad.'' School resource officers were then sent to the home, but it was determined to be a ''misunderstanding,'' Smith said.

Sixteen months before the shooting, in May 2023, law enforcement acted on a tip from the FBI after a shooting threat was made online concerning an elementary school. The threat was traced to a computer at Gray's home, Smith said.

Colin Gray was told about the threat and was asked whether his son had access to guns. Gray replied that he and his son ''take this school shooting stuff very seriously,'' according to Smith. Colt Gray denied that he made the threat and said that his online account had been hacked, Smith said.

That Christmas, Colin Gray gave his son the gun as a gift and continued to buy accessories after that, including ''a lot of ammunition,'' Smith said.

Three weeks before the shooting, Gray received a chilling text from his son: ''Whenever something happens, just know the blood is on your hands,'' according to Smith.

Colin Gray was also aware his son's mental health had deteriorated and had sought help from a counseling service weeks before the shooting, an investigator testified.

''We have had a very difficult past couple of years and he needs help. Anger, anxiety, quick to be volatile. I don't know what to do,'' Colin Gray wrote about his son.

But Smith said Colin Gray never followed through on concerns about getting his son admitted to an in-patient facility.

The trial is being held in Winder, in Barrow County, where the shooting happened. The defense asked for a change of venue because of pretrial publicity, and prosecutors agreed. The judge kept the trial in Winder but decided to bring in jurors from nearby Hall County to hear the case. Jurors were selected last week.
