WINONA, Minn. – A Winona driver left police custody with a major question hanging over his head: Would a blood sample drawn at the police station show whether illegal substances were in his body when he was stopped for an unsecured load on his vehicle? Anthony John Strouckel, 28, declined the usual local tests, which set in motion a judge’s order for a blood sample to be drawn to be sent through the state crime lab’s elaborate process for assessing levels of contamination. Those complex tests require several days to complete, Meanwhile, Strouckel has been charged with with impaired driving. The evidence cited by police: Bloodshot and watery eyes, droopy eyelids, rigidity, inability to stand still, and impaired motor movements. The arrest was about 1:30 p.m. near Broadway and Washington streets.
