Tennessee Code Title 38. Prevention and Detection of Crime § 38-5-101

No inquest shall be held by the coroner or any court of general sessions over the dead body of any person until an affidavit, in writing, is made and signed by two (2) or more reliable persons, averring the death of the person and that there is good reason to believe that the person died by unlawful violence at the hands of some other person; and without the affidavit, in writing, the coroner or court shall have no jurisdiction to hold an inquest over the dead body of any person, and all proceedings without the affidavit shall be utterly void and useless. Unless this section is literally, rigidly, and strictly complied with, and the affidavit filed with the papers, the coroner or court shall receive no fees or compensation for holding the inquest.
