In 2002, 22 states had a medical examiner system, 11 states had a coroner system, and 18 states had a mixed system. Since the 1940s, the medical examiner system has gradually replaced the coroner system and serves about 48% of the US population. The requirements to hold office vary widely between jurisdictions. The largest medical examiner's office in the United States is located in
Baltimore,
Maryland. The types of death reportable to medical examiners are determined by federal, state, or local laws. Commonly, these include violent, suspicious, sudden, and unexpected deaths, death when no physician or practitioner was present or treating the decedent, inmates in public institutions, those in custody of
law enforcement, deaths during or immediately following
therapeutic or
diagnostic procedures or deaths due to
neglect. A medical examiner's duties vary by location, but typically include: • investigating human organs like the
stomach,
liver, and
brain • determining
cause of death • examining the condition of the body • identifying unknown dead • performing other functions depending on local law. In some
jurisdictions, a
coroner performs these and other duties. It is common for a medical examiner to visit
crime scenes or to testify in
court. Medical examiners specialize in
forensic knowledge and rely on this during their work. In addition to studying
cadavers, they are also trained in
toxicology, DNA technology and
forensic serology (blood analysis). Pulling from each area of knowledge, a medical examiner is an expert in determining a cause of death. This information can help law enforcement solve cases and is crucial to their ability to track criminals in the event of a
homicide or other related events. ==Qualifications==
