Massive explosion rocks Wisconsin corn mill plant, sparks fire

Rescue crews are scouring the rubble of a corn mill plant for two employees following an explosion that killed at least one person and injured about a dozen others in southern Wisconsin. Numerous fire crews raced to the scene of  the large explosion and fire in a corn milling plant about 45 miles northeast of Madison, Wisconsin. Richards said one person was killed and two people were still missing as of Thursday morning. Authorities said about a dozen people were injured in the blast, though no details about the injuries have been released. Dozens of area police, fire and rescue agencies -- including medical flight crews -- responded after the explosion was reported around 11 p.m. Wednesday at the facility. No information has been released about what may have caused the blast. Cambria Village President Glen Williams said the fire was contained by early Thursday, but he said the building was destroyed. Williams said there were no evacuations in the area.
