A coroner is a medical professional, usually licensed and generally a skilled surgeon, who identifies the cause and circumstances of an individual’s death, supervising investigations to determine the cause of death in criminal cases, suicides, and similar situations (accidental, violent, or unexplained deaths). Usually, the coroner is employed by law authorities or a specialized medical facility. To determine the cause of death, a coroner likely will need to perform an autopsy of the body, as well as review toxicology and pathology reports. They are sometimes required to testify as expert witnesses in criminal trials. A successful coroner must be comfortable working intimately and routinely with corpses, be prepared to work extensively with his/her hands, and have a thorough understanding of the human anatomy, injuries, illnesses and many causes of death. Additionally, coroners must be good managers of others, and must be able to interact with sensitivity (especially when interacting with family members and friends of the deceased). Coroners are strictly regulated, and may only operate within his/her defined jurisdiction. Coroner positions require at least a bachelor's degree in a science or medical field, but usually require postgraduate study as well. Specific licensure qualifications vary from state to state. Coroners are usually appointed into position by the county. The work environment has some variety beyond just the morgue or similar medical milieu, since coroners must travel to various scenes of death, inventorying personal effects, observing and recording the positions and conditions of bodies and related evidence, and conferring with involved officials.
