The cause of a fire that destroyed a shed in Ashby Sunday has yet to be determined, but the Douglas County Sheriff's Office says it may have started in a home-made wood stove that was used to heat the building.

Daniel Olson, 40, of 13845 County Road 19 NW, called in the fire at 1:55 p.m. Dec. 1. The building was already burned to the foundation, the sheriff's office said, but the Evansville Fire Department was called out to assure the fire would not spread to nearby trees and brush.
