Colin Gray, the father of Colt Gray, who is charged with a deadly shooting at Apalachee High School, was aware of his son's deteriorating mental health and obsession with school shootings, including maintaining a shrine to the Parkland shooter, Nikolas Cruz. Investigators revealed that Colin allegedly gifted Colt the assault-style weapon used in the shooting and had continued to buy him accessories, despite knowing about his troubling behavior. Colt's notebook detailed plans for the attack, including estimated casualty counts and sketches of the school layout. During a court hearing, it was disclosed that Colin had previously questioned Colt about the shrine and photos of school shooters but did not take the concerns seriously. As a result of the investigation, Colin Gray faces charges of involuntary manslaughter and second-degree murder. Prosecutors aim to secure formal indictments against both father and son following the preliminary hearing.
