LANSING, Mich. (AP) — A prosecutor who’s been the top law enforcer in Michigan’s capital for nearly 20 years has been charged in three counties with hiring prostitutes and committing other crimes.

Michigan Attorney General Bill Schuette says the case against Stuart Dunnings III developed from tips during a federal human-trafficking investigation.

The 63-year-old Dunnings is the elected prosecutor in Ingham County. He was charged Monday with using the services of prostitutes in Ingham, Clinton and Ionia counties over many years.

Dunnings is also charged with pandering and willful neglect of duty. He’s lodged at the Ingham County jail. There was no immediate comment from his office.

Schuette says he’s worked with Dunnings in a professional role and is “saddened” by the charges. Ingham County Sheriff Gene Wriggelsworth says it’s a “huge betrayal.”
