Rochester, MN (KROC-AM News) - A motorist who was arrested in Stewartville Wednesday night had a blood/alcohol concentration more than four times the legal limit to drive.

When the deputy asked the man if he had been drinking, he answered, “ Duh.”

The man - identified as 35-year-old Christopher Sheehan - said he had been drinking rum and Cokes at a friend’s house in Stewartville. Sheehan said he was driving home when he was pulled over. He lives in Stacyville, Iowa, about 40 miles from Stewartville.

A breath test showed he had a blood/alcohol concentration of .35.
