Evergreen High School Shooting: What We Know About Desmond Holly’s Motive
🕯️ Colorado School Shooting: 16-Year-Old Desmond Holly Identified as Gunman in Evergreen High Tragedy
On September 10, 2025, tragedy struck Evergreen High School in Jefferson County, Colorado, when 16-year-old student Desmond Holly opened fire on campus, critically injuring two classmates before dying from a self-inflicted gunshot wound.
The shooting began just after 12:24 p.m. during lunch hours. Investigators say Holly brought a revolver and a large supply of ammunition to school on the bus. He fired multiple rounds, reloading between shots, and moved through several areas of the school in search of targets.
Authorities believe Holly was radicalized by an extremist network, though details remain under investigation. Surveillance footage captured his movements, and search warrants have been issued for his home, phone, and locker. Police confirmed they found “valuable information” at his residence.
One victim, 18-year-old Matthew Silverstone, remains in critical condition. The second student suffered non-life-threatening injuries and has been released from the hospital.
The Jefferson County Sheriff’s Office praised students and staff for their quick response and lockdown execution. “He was on a mission,” said spokesperson Jacki Kelley. “We are grateful he wasn’t more successful, but devastated that he was successful at all.”
Mental health teams have been deployed across the district, and Evergreen High School will remain closed during the investigation. The FBI and NCIS are assisting local authorities.
This incident adds another painful chapter to Jefferson County’s history, which includes the 1999 Columbine shooting. As the community mourns, questions remain about how Holly accessed the weapon and what led to his radicalization.
