BARROW COUNTY, Ga. - The second week of Colin Gray's trial began on Monday morning with testimony by his ex-wife and Colt Gray's mother, Marcee Gray.
So far, Marcee Gray's testimony has focused heavily on Colt's deteriorating mental health and the family's unstable living situation.
Marcee revealed that as early as 2021, school officials alerted her that Colt had bypassed internet filters to search "how to kill my dad." She described Colt's personality shift after she moved away in 2022, leaving him in his father's care. Upon seeing him again, she noted he was "aggressive and unpredictable," testifying that he used knives to vandalize the family car and home.
Marcee detailed a "full-blown panic attack" Colt suffered in July 2024, where he was found "hunched over and crying out," reportedly asking for someone to call 911.
A central theme of her testimony was the lack of communication from Colin Gray. She alleged that Colin "blocked her phone number" and refused to facilitate visits, leaving her in the dark about Colt's access to firearms.
The prosecution is using Marcee’s testimony to bolster its claim that Colin Gray was "criminally negligent" by providing his son with a SIG Sauer M400 rifle despite being aware of these severe mental health crises.
Earlier in the trial, jurors heard body camera footage from the day of the shooting where Colin Gray was recorded saying, "God, I knew it," upon hearing there was a lockdown at the school—a phrase the state argues proves he was aware of the immediate danger his son posed.
The backstory:
The second week of testimony in the trial of Colin Gray began Monday morning, following several days of emotional witness accounts and video evidence presented to jurors.

Colin Gray Trial: Chilling texts & "shrine" revealed
The first week of testimony in the Colin Gray trial concluded on Feb. 20, 2026, with disturbing revelations about the shooter’s home life and mental state. Prosecutors presented evidence of a Parkland-themed "shrine" and desperate text messages sent by Colt Gray just days before the attack. Our Kim Leoffler breaks down the week’s evidence and what to expect when Marcee Gray takes the stand Monday.
What we know:
During the first week, prosecutors laid out their argument that warning signs were overlooked in the months leading up to the Sept. 4, 2024 shooting at Apalachee High School. The State called students, school staff and family members to testify, including Colt Gray’s grandmother, who told jurors she bought ammunition for her grandson after confirming it was approved by his father.
Jurors also reviewed police body camera footage from a prior visit to the Gray home tied to alleged online threats, as well as cellphone and body camera video from the day of the shooting. A school counselor described the district’s digital monitoring system, which flags certain words on student devices for follow-up.
What's next:
Testimony is expected to resume Monday with Colt Gray’s mother, Marcee Gray, anticipated to take the stand. Her appearance could provide jurors additional insight into the family dynamic and events leading up to the shooting.
Colin Gray has pleaded not guilty. His defense team argues he could not have predicted the attack and disputes the State’s claim that he bears criminal responsibility.
