Prosecutors played clips of the recorded conversations between Colt Gray and his mother during the teenager's sentencing hearing Tuesday. He chatted with other people online about gaining notoriety through a school shooting and his admiration for previous mass shooters. There were aspects of his preparation and behavior before and after the Apalachee High School shooting that mimicked other mass shooters, Gilleland testified. He spoke frequently with his mother, Marcee Gray, by phone from a youth detention center in the months after the shooting. He also repeatedly asked his mother to communicate with one of the people he'd been speaking to online before the shooting to pass along messages to their online community.
