N.C. Gen. Stat. § 152-1
In each county a coroner shall be elected by the qualified voters thereof in the same manner and at the same time as the election of members of the General Assembly, and shall hold office for a term of four years, or until his successor is elected and qualified.
A vacancy in the office of coroner shall be filled by the county commissioners, and the person so appointed shall, upon qualification, hold office until his successor is elected and qualified. If the coroner were elected as the nominee of a political party, then the county commissioners shall consult with the county executive committee of that political party before filling the vacancy, and shall appoint the person recommended by that committee if the party makes a recommendation within 30 days of the occurrence of the vacancy; this sentence shall apply only to the counties of Alamance, Alleghany, Avery, Beaufort, Brunswick, Buncombe, Burke, Cabarrus, Caldwell, Cherokee, Clay, Cleveland, Davidson, Davie, Graham, Guilford, Haywood, Henderson, Jackson, Madison, McDowell, Mecklenburg, Moore, New Hanover, Polk, Randolph, Rockingham, Rutherford, Stanly, Stokes, Transylvania, Wake, and Yancey.
When the coroner shall be out of the county, or shall for any reason be unable to hold the necessary inquest as provided by law, or there is a vacancy existing in the office of coroner which has not been filled by the county commissioners and it is made to appear to the clerk of the superior court by satisfactory evidence that a deceased person whose body has been found within the county probably came to his death by the criminal act or default of some person, it is the duty of the clerk to appoint some suitable person to act as coroner in such special case.
