WINONA, Minn. — A police officer, who had stopped a Winona man about a cracked windshield, spotted an orange-tip syringe on the curb. “Yours?” he asked. The driver said no. But the officer was suspicious. The man, Dion Edward Wadley, 26, was talking rapidly and sweating profusely despite the cool evening.  This was about 9:45 p.m. The officer, a drug-recognition expert, found indictors of impairment in sobriety exercises. As this was going on, a second orange tip syringe fell from Wadley’s trousers, the officer said. This was near Kraemer Drive and Druery Court on the Far West End. Wadley was taken into custody for driving without a valid license, for no proof of insurance, and for suspicion of driving under the influence of a controlled substance. At jail a urine sample was taken. Test results will determine what charges are recommend to the county attorney.
