At least three students are in critical condition after a shooting at Evergreen High School in Evergreen, Colorado, where more than 100 law enforcement officers are working to clear the school “room by room” as it remains on lockdown, officials said.

No suspects are in custody and and authorities are working to determine whether there was one or multiple shooters involved, said Jacki Kelley, public information officer for the sheriff’s department.
