WINONA, Minn. – A St. Paul driver was arrested after showing signs of impairment during a traffic stop, police said. Tayton Ann Hansen, 21, failed a field sobriety test. Because officers suspected drugs, a blood draw was taken and sent to a state lab for tests that will determine what charges are warranted. Such tests usually have a three-day turn-around. The stop was for speeding in the 200 block of West Sarnia Street about 8:40 p.m.
