One person was seriously injured in a one-vehicle alcohol-related rollover crash in Dodge County. The crash happened shortly after 10:30am Wednesday on County Road MM near Robin Road. A preliminary investigation shows an SUV was eastbound on MM, failed to negotiate a curve, crossed over the center line, entered a ditch and rolled over ejecting the driver. A 38 year old Watertown man was flown by helicopter to a hospital with serious, but non life-threatening injuries. He was arrested for 5th Offense Operating a Motor Vehicle while Intoxicated. The crash remains under investigation.
