Michael Wawee Jr. announced his resignation on Thursday. The Republican from Walker was arrested earlier this month.
He's accused of overcharging families for the engraving of grave markers while working as a salesman for the Roman Catholic Diocese of Grand Rapids. Police said the diocese was not aware of the overcharging.
In a statement distributed by the county, Wawee says he needs to focus his energy on his family and proving his innocence.
The Kent County Board of Commissioners will have 30 days after Wawee's Feb. 28 resignation to appoint a replacement for the rest of the current term, which runs through the end of the year.
