“There did seem to be some struggle going on when they got there; we don’t know if that was students or security or officers,” Ms. Nicholson-Kluth said. She said she did not know if anyone had been killed.
Ms. Nicholson-Kluth said she did not have information about the injured students, their ages or the severity of their injuries. Law enforcement officers may find more injured students or additional suspects as they move through the school, she said.
Ms. Nicholson-Kluth said she did not have information about how the suspects were caught.
Local news media showed video footage of tear-stricken parents gathering near the school as at least two air ambulance helicopters arrived at the scene after the shooting, which was reported before 2 p.m.
“It is a very evolving situation,” Ms. Nicholson-Kluth said. “They are still treating it as an active situation.”
Gov. Jared Polis of Colorado said the state government was monitoring the situation.
“We are making all of our public safety resources available to assist the Douglas County Sheriff’s Department in their effort to secure the site and evacuate the students,” he said on Twitter. “The heart of all Colorado is with the victims & their families.”
