There's been another school shooting, this time at Evergreen High School in Colorado.

Initial reports say that at least three people, probably students, are in critical condition after being hospitalized.

A report from KDVR television said authorities in Jefferson County, which encompasses the foothills community of Evergreen about 25 miles west of downtown Denver, said there was an "active assailant" at the school.

A spokesperson for CommonSpirit St. Anthony Hospital in Lakewood told FOX31 that three people are in the hospital in critical condition related to the incident.

Authorities revealed a 911 call came in about 12:40 p.m. Mountain Time, and a warning was issued that people who have kids at the school should not try to go there, as it still was "an active scene."
