Classes are canceled at Evergreen High School this week after a student shot two of his schoolmates before turning the gun on himself last Wednesday.

Jefferson County officials have not confirmed when the high school will reopen.

As of Friday, both students shot by 16-year-old Desmond Holly remained in critical condition at separate hospitals. One was being treated at CommonSpirit St. Anthony Hospital in Lakewood, and the other had been transferred to Children's Hospital Colorado in Aurora.

Updates on their conditions were not immediately available Monday morning from either hospital.

Desmond, armed with a revolver, shot his schoolmates -- including 18-year-old Matthew Silverstone -- at Evergreen High School in the foothills west of Denver and then himself. He died from his injuries at the hospital.

The second student shot has not been publicly identified.

Authorities said the high school needed "cosmetic" repairs before it's able to reopen, including replacing broken windows, fixing damaged lockers and cleaning up "fluids."

Students enrolled in the Jeffco Virtual Academy will still have class, but can expect a light catch-up week, according to the school district. Optional athletic practices will resume off-site Monday afternoon, mostly as a way for teams to connect.

Social media accounts that appeared to belong to Desmond, the 16-year-old shooter, embraced white supremacist views and were littered with references to mass shootings and Holocaust denial, The Denver Post found. Desmond also showed an interest in mass shooters in the days before the attack.

The teenager was "radicalized through an extremist network," Jefferson County Sheriff's Office spokeswoman Jacki Kelley said. She was unable to release additional details, including a potential motive.

Experts said Desmond's online footprint reflects a new wave of nihilistic violent extremism that calls for violence as a way to destroy society.

This is a developing story and may be updated.
