Oak Lawn Fire Chief George Sheets said the fire broke out in a strip mall on 95th Street about 200 feet west of South Cicero Avenue shortly before 3 p.m.
Up to 70 firefighters from 22 engine companies were fighting the fire, which Sheets said was under control within an hour.
There was initially some confusion about the fire’s origin, Kaufmann said. Last Friday, a fake pipe bomb was found near railroad tracks near the David’s Bridal down the street.
But no explosion was heard Wednesday at Eva’s, Radio Shack or surrounding businesses, either by employees or customers, said Oak Lawn Division Chief Mike Kaufmann.
Arson investigators will begin formally examining the property on Thursday morning.
"There's too much smoke and fire at this point to assume anything," said Kaufmann.
The structure will likely need to be razed, he said. The middle businesses were a total loss; two stores at either end -- a mattress store and Miss Fantasia’s lingerie -- also suffered extensive smoke damage.
Ashley Kuhl, of Crestwood, said her wedding dress was destroyed in the fire. Her wedding is planned for Dec. 4.
