The mother of accused Apalachee High School shooter Colt Gray testified that she urged his father to lock up firearms before the September 2024 shooting. Marcee Gray told jurors she warned Colin Gray that the guns needed to be secured, saying "They need to be locked somewhere" after Colt expressed interest in completing a "school shooter outfit."

Prosecutors allege Colin Gray gave his 14-year-old son the semiautomatic rifle used in the attack as a Christmas gift despite warning signs. The shooting killed two teachers and two students, with Colt facing 55 counts including murder. Colin Gray faces 29 counts including second-degree murder and involuntary manslaughter for allegedly failing to secure the weapon.

Marcee Gray testified about Colt's fascination with Nikolas Cruz, the Parkland shooter, which she initially dismissed as similar to her own interest in true crime. She recounted Colt joking about finishing his "school shooter outfit" with a tactical vest his father had given him. The trial highlights growing efforts to hold parents accountable in fatal school shootings, with prosecutors arguing Colin Gray ignored multiple red flags about his son's mental state and access to weapons.
