If any judge or circuit court commissioner conducts an inquest as to the death of a stranger or of a person whose identity is unknown or whose body is unclaimed or if the district attorney determines that no inquest into the death of such a person is necessary and the circuit judge has not ordered an inquest under s. 979.04 (2), the coroner or medical examiner shall cause the body to be decently buried or cremated and shall certify to all the charges incurred in taking any inquest by him or her and to the expenses of burial or cremation of the dead body. The charges and expenses shall be audited by the county board of the proper county and paid out of the county treasury.
