FLINT, Mich. (AP) — Attorneys for Michigan’s health director say the involuntary manslaughter and other charges he faces that are tied to the Flint water crisis are baseless.

State Health Department Director Nick Lyon’s lawyers, Chip Chamberlain and Larry Willey, also say the facts of the case don’t support Michigan Attorney General Bill Schuette’s claims.

Lyon was among five officials charged Wednesday with involuntary manslaughter as part of the investigation into Flint’s lead-contaminated water. They are blamed in the death of an 85-year-old man who had Legionnaires’ disease.

A sixth official was also charged, but not with manslaughter.

Lyon is accused of failing to alert the majority-black population about an outbreak of Legionnaires’ disease in the Flint area, which has been linked by some experts to poor water quality in 2014-15.

Lead leached into some Flint homes after officials tapped into the Flint River in 2014.
