Death investigation statutes and practices vary among the 50 states. W
e reviewed the Model Postmortem Examinations Act, recommendations of t
he National Association of Medical Examiners. the College of American
Pathologists' ''criteria for autopsies,'' and the death investigation
statutes and practices in each state. By consolidating the terminology
from these various information sources, we developed a list of death
categories for which investigation by medical examiners or coroners in
the United States is either mandated, commonly performed, or recommen
ded. The list contains specific categories of death, which fall under
these three more general areas: 1) unexpected and unexplained deaths,
2) deaths from intentional and unintentional external causes, and 3) d
eaths that fall under specialized categories related to the decedent's
age, environment, or medical conditions, or to the method of bodily d
isposition. To promote greater uniformity in the death investigation p
ractices among states, we recommend that the Model Postmortem Examinat
ions Act be modified to explicitly recommend certain types of deaths f
or investigation and that states modify their death investigation stat
utes to conform to such provisions. Presently, in states where death i
nvestigation statutes lack specificity in detailing the types of death
s that should be reported for possible medico-legal investigation, our
recommendations, if not in conflict with local statutes. might be use
d as practice guidelines for the reporting and investigation of certai
n types of deaths.
