Door County authorities say they don’t know why 56-year-old David J. Marsek was lying in the road when he was hit. The Milwaukee man was killed when a car hit him late Sunday night and he was pronounced dead at the scene. Investigators say they think alcohol might have been involved in the fatal accident. The vehicle which hit Marsek was driven by a 36-year-old man from Sister Bay. The road in the town of Liberty Grove was closed to traffic for nearly eight hours while evidence was collected.
