SHEBOYGAN, Wis. (WTAQ) - State and local authorities say a fire last week that destroyed the Lakeshore Pallet Company near Oostburg was started on purpose.

At a news conference Tuesday morning, Sheboygan County Sheriff Michael Helmke announced a $10,000 for information that would solve the case.

All four buildings at the Lakeshore complex were destroyed, and an early report said accelerants were spotted in more than one location. The company made wooden pallets, and pellets for wood-burning stoves.
