Second day of testimony ahead in Colin Gray trial

Tuesday will mark the second day of testimony in the trial for Colin Gray, father of accused Apalachee High School shooter Colt Gray. The prosecution is trying to prove Colin knew his son was a serious risk to the safety of others at school and didn't do anything to stop it. 

What we know:

Gray is charged with nearly 30 felony counts, including second-degree murder and involuntary manslaughter. Prosecutors allege he gave his son, Colt Gray, access to a SIG Sauer M400 rifle, knowing there were warning signs, and failed to prevent the Sept. 4, 2024, attack.

Testimony on Monday included accounts from teachers, administrators and Judd Smith, who described what they witnessed inside the school. The proceedings laid out two sharply different portrayals of the father-son relationship.

What they're saying:

Prosecutors argued Colin Gray purchased the rifle as a Christmas gift in December 2023, months after law enforcement warned him about alleged online threats tied to his son. They contend he continued allowing access to firearms despite concerns about the teen’s behavior.

The other side:

The defense countered that Colt Gray was living a "double life," sending affectionate text messages to his father while secretly drafting violent plans in private phone notes and online accounts. Defense attorneys also said the teen’s mother was aware of his interest in school shootings but did not share those details with Colin Gray.

"The evidence will show a teenager who is struggling mentally, a teenager who was deceptive — a teenager who hid his true intentions from everyone," the defense told jurors.

Colt Gray is awaiting his own trial and remains behind bars.

What's next:

As testimony continues, jurors are expected to hear more about the months leading up to the shooting — including prior visits by child welfare officials, the family’s contacts with law enforcement and school officials, and the state’s timeline of alleged warning signs. Prosecutors have said evidence will include information about online threats, firearm access in the home and the circumstances surrounding how the rifle used in the attack was obtained.

The trial is being held in Barrow County with a jury selected in Hall County. Jurors have been instructed to avoid news coverage and social media about the case and to decide the matter solely on evidence presented in court.
