All but one had been treated and released by Friday morning, according to the spokesman, Capt. Roman Clark.
Firefighters responded to calls for fire in part of the old Gunther Brewery complex in the 1200 block of S. Conkling St. at about 2 p.m. Thursday. Clark said it wasn't brought under control until 5:45 a.m. Friday — more than 15 hours later.
The cause of the fire, primarily confined to the cork-covered walls on the third and fourth floors of the building, is still under investigation.
