A Pope County man was sentenced to 4 years in prison Friday for the July crash that killed the five-month-old son of Southwest Minnesota State Basketball Coach Brad Bigler. 38-year-old Dana Schoen of rural Starbuck admitted that he was driving drunk when his pickup struck the SUV driven by Heather Bigler of Marshall. Bigler’s infant son died in the head-on collision, and Brad Bigler and his wife’s grandmother suffered serious injuries. Schoen’s blood alcohol level was .32 at the time, or four times Minnesota’s legal limit. It was his third conviction for driving under the influence. He will now be required to submit to random drug and alcohol testing and remain out of bars and liquor stores as part of his sentence.
