LEWISTON, Minn. – A deputy caught up with a speeder on U.S. Highway 14 at Lewiston’s east end and discovered, he said, that it was no mere speeding issue. The driver, Caroline Marie Adams, 28, of Winona, was drunk, the deputy said. Also there was an existing warrant for her arrest. An on-scene breath test found Adams’ blood-alcohol at 0.10%, the deputy said. Later at the jailhouse in Winona the level was down to 0.09%. Both readings exceeded the state’s definition for impaired driving. At the traffic stop, the deputy said, Adams first gave a false name and a birth date that would have put her in her 60s. But, he said, she sure didn’t look 60. Amid her “very excited chatter,” as the deputy described it, Adams changed her name to her real identity and age but denied drinking. She then failed field sobriety tests on the spot, the deputy said. Her speed, which led to the stop, had been 69 mph through the 60 zone at the Arches.
