"It's all caved in," Aurora Fire Capt. Mike Anderson told the Denver Post. "The walls were pushed put."
No one was inside the Save A lot food store when the roof caved in Friday morning and no injuries were reported. Officials evacuated employees and patrons from other stores in the Hoffman Heights Shopping Center as a precaution.
The supermarket building, built in the 1950s, was not expected to reopen anytime soon.
