DENVER (AP) — In a heartbreaking incident, three teenagers have been hospitalized in critical condition after a shooting at Evergreen High School, located about 30 miles west of Denver. Authorities revealed that the event took place around midday on Wednesday. Jefferson County Sheriff’s Office spokesperson Jacki Kelley confirmed that all individuals transported to the hospital are believed to be students, but further details concerning their injuries were not immediately available.

As of mid-afternoon, all three students were either in the emergency room or undergoing surgical procedures at St. Anthony Hospital in Lakewood, Colorado. Hospital CEO Kevin Cullinan stated that, so far, he does not expect any additional victims related to the shooting.

Details surrounding the shooter or the number of potential shooters remain unclear. Kelley noted that a significant response from local law enforcement was initiated, with over 100 police officers from various agencies rushing to the school to assist in managing the situation.

This incident has drawn parallels to the tragic Columbine High School shooting in 1999, where the same sheriff’s office responded to an event that claimed the lives of 14 individuals, including a woman who succumbed to her injuries earlier this year.
