Sept. 10 (UPI) -- Four students were injured Wednesday after one of them opened fire at a Denver-area high school, the Jefferson County Sheriff's Office said.
The shooting happened around 12:34 p.m. at Evergreen High School, JCSO spokeswoman Jacki Kelley said in a news briefing.
It wasn't revealed who injured the suspect, but the JCSO said it didn't believe law enforcement fired any bullets. Kelley declined to provide any details such as a name, age or gender about the shooter due to his age.
"I don't know if our suspect is even old enough to drive," she said during the briefing.
Three of the students, including the suspected shooter, were transported to CommonSpirit St. Anthony Hospital in Lakewood, Colo., in critical condition. A fourth student was also taken to the hospital, but the cause of their injuries was unclear.
