Fire crews responded to the building along East Alameda Avenue after “reports of smoky conditions” on Saturday, the agency said on Twitter, and officials were “looking for danger” when the explosion happened.
Two people were taken to hospital with non-life-threatening injuries. A third victim was transported to another hospital, but Aurora Fire Rescue did not specify his condition.
The cause of the explosion is unknown.
“Heavy damage occurred from an explosion on the west side of the structure,” Aurora fire officials said Saturday afternoon. Authorities found “structural damage” as a result, although officials are still working to determine the extent and severity of the damage.
“I heard a really loud boom and I said, ‘Don’t look back, don’t look back, keep walking,'” Goodwin told the station. “Like, ‘You don’t want to see what just happened.’ “
At short notice, residents were moved to a local shelter with the help of the Red Cross, Aurora Fire Rescue said. “Long-term accommodation will be coordinated by (the Red Cross) as needed.”
Community members were asked to stay away from the building.
