A Waupaca man will serve time in the county jail on a felony drunk driving conviction. 58 year old Randal J. Frank was sentenced earlier this week on his 6th operating while intoxicated. Frank was given a one year county jail sentence, with the last 90 days of that stayed, to be used at the discretion of his probation agent. Frank was placed on probation for one year. He was arrested on the city’s west side in May, driving with a blood alcohol concentration of .141 percent. Frank also lost his driving privileges for 2 years, and was ordered to install an ignition interlock device for three years.
