Rock County Sheriff's Department and Janesville EMS were dispatched to S. LaPrairie Town Hall Road near E. Maple Lane. There, they found 43-year old Jimmy Walls sleeping in his Dodge pickup that was pulled to the side of the road.
Walls admitted to drinking before he got in the car and deputies found an open bottle in the vehicle. A preliminary breathalizer test shows Walls' BAC level was .279.
Walls now faces his seventh OWI conviction.
