Shooting
On September 10, 2025, at approximately 12:30 p.m. MDT, a student at Evergreen High School opened fire with a revolver inside and outside the building.[6] According to authorities, the shooter fired about 20 rounds before taking his own life.[7]
Two students were critically injured during the attack. An 18-year-old student was shot in the head and chest, while a 14-year-old student was also seriously injured.[8] Security doors prevented the suspect from entering additional areas of the school, which authorities say likely prevented further casualties.[9]
Perpetrator
The shooter was identified as 16-year-old Desmond Holly, a student at the school.[10] Investigators reported that Holly had been exposed to extremist online material and appeared to have adopted neo-Nazi ideology in the months before the attack.[11] Officials also indicated that he may have expressed interest in previous school shootings, though the precise motive remains under investigation.[12]
Victims
The 18-year-old victim, later identified as Matthew Silverstone, suffered gunshot wounds to the head and chest and underwent emergency surgeries. He survived after doctors resuscitated him twice during transport to the hospital.[13]
The 14-year-old victim was also critically injured but later released from the hospital in early October 2025.[14] According to his family, he confronted the shooter at close range, giving other students critical time to escape.[15]
Hundreds of residents attended a community vigil the day after the shooting, with local leaders emphasizing unity and support for students and families.[18] A temporary support center was established to provide counseling services for students, parents, and staff.[19]
In the weeks after the shooting, officials investigated several potential threats reported on social media. These were ultimately determined to be either unfounded or trauma-related posts from students processing the event.[20]
