WINONA, Minn. – The officer made a traffic stop for a dangling item obscuring the windshield, then, the officer said, he smelled alcohol. Kayla Minnie Hacker, 21, of Rochester, was charged with drunken driving. Her blood’s alcohol content was measured twice — once roadside at the 0.08% impairment threshold and then a tad higher at 0.084% at the jail house. The officer also noted awkward finger dexterity, slurred speech, and bloodshot and watery eyes. The stop was about 1:50 a.m. in the 450 block of Huff Street, near Winona State University.
