A 34-year-old Janesville man is facing a charge of 5th offense operating while intoxicated after being arrested over the weekend. The Rock County Sheriff's Office says Jeremy M. Maurer was pulled-over while traveling south on Highway 51 near Manogue Rlad around 7:00 o'clock Saturday night. The deputy says he could smell a strong odor of intoxicants on Maurer's breath. A breath test registered a .23, almost three times the legal limit. Maurer was also ticketed for speeding.
