RACINE COUNTY, WI (WTAQ) - A Racine County man killed in a one-car crash last Friday might have fallen asleep at the wheel.

Raymond Pousha of Waterford tells the Racine Journal Times that his brother Ken had a bad case of asthma, and he’s been groggy before while driving.

Authorities said 50-year-old Kenneth Pousha was going west on County Trunk “L” when his car spun into a ditch, hit a culvert, went airborne, rolled over, and landed on its wheels. Pousha was thrown out of the vehicle, and was found a few feet away.

The crash remains under investigation.

His brother said Kenneth Pousha was driving to work at the time, and he was only a half-mile from the brother’s custom painting shop when the crash happened.
