12. The coroner may summon to appear before him and examine under oath any person who is, in his opinion, in a position to enlighten him regarding the causes and circumstances of the death; he may retain for such purpose, if necessary, the services of an interpreter who shall be entitled to the fees fixed by the tariff established for such purpose by the Government.
The coroner may also order an internal or external examination of the body, provided that he first draws up a declaration in writing, attesting under his oath of office that the examination is necessary to ascertain that death did not occur as a result of violence or negligent or culpable conduct of a third person.
