VIOLA, Minn. – A woman’s body was found along a rural road west of Viola by a man mowing tall grass. The man spotted an arm sticking out under a tarp about 6 p.m. Olmsted County deputies established a perimeter until investigators could arrive. The body was too badly decomposed for immediate identification, investigators said. The body was on County Road 2, which leads out of northeast Rochester 14 miles to Viola. Because the death seemed suspicious, the state Bureau of Criminal Apprehension was called in.
