Farmers in the Sauk Prairie area said they hoped the fire-damaged McFarlane's store rebuilds soon, even as the cause of the fire may never be known.
The state Fire Marshal's office has finished its investigation and wasn't able to prove the fire's cause with an acceptable level of certainty, a spokeswoman for the state Department of Criminal Investigation.
The blaze destroyed McFarlane's True Value hardware store, but spared the company's tire, equipment and rental businesses, allowing owner John McFarlane to consider moving them to a temporary location.
"We're devastated by the loss, but it's just inventory," said McFarlane, a third-generation owner. "It can be replaced, and it will be replaced. That's our plan."
McFarlane said he was thankful no one was hurt in the fire, and said he was in the process of getting a temporary facility on U.S. Highway 12.
State investigators have turned over the scene to the insurance company.
