BOONVILLE, Missouri — A saw operation building was heavily damaged by fire at Baillie Lumber on West Street Wednesday night, according to the Boonville Fire Department. The alarm was raised at 9:16 p.m., while the lumber yard was closed for the day, said Boonville Fire Chief David Pritchard Jr. “The fire was mainly around an enclosed building where the saw operator sits,” Pritchard stated. “We went right inside, but the problem is it got into the walls.” Pritchard said the fire spread into the steel walls of the saw building and “we had an excavator come in and peel the steel back.” …No one was injured, the chief said. He believes the company has insurance. …The cause of the fire remains under investigation. Pritchard said it may have been electrical or mechanical in nature.
