Waterloo firefighters spent much of last(Mon) night trying to knock down a fire inside an old commercial building at 105 East 10th Street.
One firefighter was treated for heat exhaustion, but is expected to be okay, according to his battalion chief.
After passersby spotted smoke coming from the building shortly after 8:45 pm and a crew arrived, dense smoke and the layout of the interior made it tough to locate exactly where the fire was coming from.
Eventually, a person familiar with the building arrived and helped firefighters locate a pile of burning debris on top of some pallets. Investigators say it looked like someone had set the fire and building appeared to be a way station for the homeless.
The nearly-10,000 square foot, 116-year old warehouse had been used in the past by Crystal Distribution, but the city took possession of it in 2013 and planned to tear it down for housing in the area.
