I know a man (not in Oklahoma) who was hit head on by a drunken pregnant woman. He lost his leg because of that accident, he nearly died. His young boy was also in that car.
As a result of the physiology of his injuries, his blood alcohol rose over a span of several hours. Initially his blood alcohol level was zero. Over a year later, HE was charged with a DUI despite the fact that he hadn’t been drinking.
Therefore, my point is that even blood alcohol levels aren’t always accurate with regard to DUI.
Something is way wrong with that story...............
