DENVER — Multiple schools or school districts around Colorado on Wednesday received reported incidents or threats, many of which proved unfounded, leading to orders for students to shelter in place or be evacuated as a safety precaution.
In Boulder, a 911 call was received by communications at 8:33 a.m. about an active shooting at Boulder High School, said Police Chief Maris Herold at a late-morning news conference outside the school.
The caller, likely a man, according to Herold, said that he was armed and was firing shots. Gunfire was heard in the background.
