Michigan is charging its top medical official, Dr. Eden Wells, with involuntary manslaughter. On Monday, state prosecutors said Legionnaire's disease caused at least 12 deaths as a result of the contaminated water supply in Flint, Michigan. Wells will be the sixth official to be faced with such chargers due to the water crisis. In Wells' case, prosecutors claimed she lied about knowing the outbreak started and threatened independent researchers who tracked the source of the disease. Flint has been left without clean water since 2014.
