Fire did an estimated $500,000 in damage to a Waubonsie Valley High School storage building and its contents Saturday night in a blaze that erupted while the homecoming dance was taking place at the nearby Aurora school.
The dance was not interrupted, according to Aurora Fire Department Deputy Chief John Lehman, but about 20 Aurora firefighters fought the blaze for more than a half-hour before getting it under control.
Firefighters were called to the out building on the north end of the high school property, just off the adjacent parking lot, at about 8:23 p.m., Lehman said.
The fire's cause is under investigation by the department's arson investigation team but arson is not suspected because doors were locked and there was no forced entry to the building.
The 30-foot-by-50-foot cinder block building held maintenance equipment, lawn equipment, tractors and gas storage, Lehman said.
No injuries were reported.
