During a press conference following the incident, Jacki Kelley, spokesperson for the sheriff’s office, mentioned uncertainty about whether the shooting occurred inside or outside the school and only confirmed the use of “a handgun.” Authorities clarified that no officers discharged their weapons during the event.
Kelley reported that calls about the shooting began just before 12:24 p.m., prompting officers from across the Denver metropolitan area to respond and assist, according to KCNC. However, she also noted that the investigation is in its early stages.
“Honestly, I don’t even know if the suspect is old enough to drive,” Kelley said.
A mother said her freshman son told her he was near a door in the lunchroom when the shooting started and heard 15 to 30 gunshots.

“I know drills have been conducted in classrooms, but this happened during lunch,” she said, reflecting the confusion students felt. “Many mentioned they were unsure of what to do, like a lockdown drill, given the timing.”
Sam, a freshman who spoke with KDVR, recounted being in the bandroom when the shooting started. He described feeling disoriented upon hearing the initial gunfire, noting that debris struck his forehead.
“I saw him right in front of me and everything, he was right on the other side of the room and the door, and I saw the gun and everything pointed at me and everybody else … it was … I think he broke the window, and tried to get through, but don’t think he did,” Sam said.
The school district cancelled all school activities in the county for the remainder of Wednesday.
Kelley said that officers were sweeping the school for evidence and would be executing search warrants at the shooter’s home.
