There is enough information in the article to hang this individual. She has a chronic illness that she has been treated for a lengthy period of time. Knowing that she is afflicted with this disease and it's symptoms, she either shouldn't be driving, or take measures (wear a diaper) to prevent this sort of surprise result. Defacating on ones self should not cause you to lose complete control of the vehicle. That explanation is insufficient cause for the accident. She failed a field sobriety test. If we believe her story, she says she is not full of s***. I think otherwise.
