WINONA, Minn. – A deputy stopped a Lewiston man for speeding, 51 mph in a 40 zone, then realized the issue was more than speed. The man’s responses to questions were slow and delayed, the deputy said. The man smelled of alcohol. His eyes were bloodshot, his speech slurred. He was unsteady. A field breathalyzer test showed 0.04% alcohol – only half the threshold for legal impairment. Tyler Carleton Tayne, 20, was taken to jail for testing on a device with greater capabilities than field breathalyzers. The new sample was sent to the state crime lab for testing, which will determine whether a controlled-substance charge is warranted. The stop was about 11:20 p.m. on Riverview Drive.
