A 42-year-old rural Potosi man faces drunk driving and battery charges after a crash in the Town of Potosi Thursday night.

David Mahr faces charges of second-offense driving while intoxicated, and “multiple” counts of battery to a police officer and emergency personnel, according to the Grant County Sheriff’s Department. Mahr also is being cited for failure to stop at a stop sign, operating left of center, failure to maintain control of a vehicle and failure to wear a seat belt.

Mahr was driving south on Slazing Road around 8 p.m. when, according to the sheriff’s department, he failed to stop at the stop sign at Brewery Hollow Road. Mahr’s vehicle rolled onto its side. Mahr had to be extricated from his vehicle by the Potosi Fire Department.

According to the Sheriff’s Department, Mahr had just come from the Roadhouse Bar in Potosi and was “heavily intoxicated,” and was also under the influence of heroin. Mahr was combative with officers, EMTs and emergency room staff at Grant Regional Health Center in Lancaster, where Potosi EMS took him. Mahr was later taken by Medflight helicopter to UW Hospital in Madison.
