Preliminary investigation into the suspect who shot and injured two fellow students at Evergreen High School Wednesday found that he was “radicalized by some extremist network,” according to Jefferson County Sheriff’s Office spokesperson Jacki Kelley. Officials have identified the shooting suspect as 16-year-old Desmond Holly, who died at a Lakewood hospital on Wednesday from a self-inflicted gunshot wound he sustained after the shooting. The suspect’s family has been cooperative with authorities as they investigate and plan to search his home, phone and school locker, Kelley said. “He couldn’t get to those kids.”Silverstone’s family released a brief statement through the sheriff’s office on Thursday. Multiple agencies are supporting the Jefferson County Sheriff’s Office in the investigation “because there’s so many crime scenes within the school and outside the school,” Kelley said.
