Fond du Lac County has hired an interim medical examiner as a search for a fullt-time replacement continues. The county board this week voted to appoint the office operations manager Daniel Krieser to the post. County executive Al Buechel says while Krieser is not a doctor and cannot do autopsies he is trained in the field of death investigations. Buechel says the search for a chief medical examiner continues after longtime medical examiner Dr. Doug Kelly announced his resignation.
