At least two students are in critical condition after being shot at Evergreen High School in Colorado on Wednesday, according to the Jefferson County Sheriff's Office.
Authorities said the students were taken to a local hospital for treatment. Hospital officials said the victims are under 18, but did give any further details.
Officials said the suspected shooter, who is believed to be a student, was also injured and is in critical condition.
Jefferson County Sheriff's Office Public Information Officer Jacki Kelley said she believes that law enforcement did not fire any rounds during the incident, so it is not clear how the suspect was injured.
The shooting happened on school grounds, but it is unclear if the shooting took place inside or outside of a school building.
