Your question needs to be articulated. Although you've provided us with
Turkish translation, without knowing the functionality of "Coroner" in the
law system you are refering, it is hard to answer if Turkish Law System
involves a lawman of that functionality.

For a brief answer, there are 2 basic types of lawmen in Turkish Law
System: Judges and Public Prosecuters. Public Prosecuters work in a
"district" basis under a chief prosecuter of that district who is also under
chief prosecuter of that city.

Judges do not have a chain of command like that and directly chained to
"Judges and Prosecuters High Council" (=Hakimler Savcılar Yüksek Kurulu)
