January 14, 2021 LANSING, Mich. (AP) â Michiganâs former health director was charged Thursday with involuntary manslaughter in the deaths of nine people who got Legionnairesâ disease during the Flint water crisis as prosecutors revisit how the cityâs water system was contaminated with lead and bacteria during one of worst human-made environmental disasters in U.S. history. Nick Lyon pleaded not guilty during an appearance in a Genesee County court. Moments later, his old boss, former Gov. Rick Snyder, also pleaded not guilty to misdemeanor charges of willful neglect of duty in Flint. They were among several people summoned to court to face charges, the result of a renewed 19-month investigation launched by the attorney generalâs office after Dana Nessel, a Democrat, was elected.
