An unnatural cause of death results from an external cause, typically including homicides, suicides, accidents, medical errors, alcohol intoxications and drug overdoses. [6] [7] Jurisdictions differ in how they categorize and report unnatural deaths, including level of detail and whether they are considered a single category with subcategories, or separate top-level categories.
Glessner Lee called them the Nutshell Studies because the purpose of a forensic investigation is said to be to "convict the guilty, clear the innocent, and find the truth in a nutshell." [ 10 ] Students were instructed to study the scenes methodically—Glessner Lee suggested moving the eyes in a clockwise spiral—and draw conclusions from the ...
A forensic autopsy is used to determine the cause, mode, and manner of death. Forensic science involves the application of the sciences to answer questions of interest to the legal system. Medical examiners attempt to determine the time of death, the exact cause of death, and what, if anything, preceded the death, such as a struggle.
Thanatology is the scientific study of death and the losses brought about as a result. It investigates the mechanisms and forensic aspects of death, such as bodily changes that accompany death and the postmortem period, as well as wider psychological and social aspects related to death. It is primarily an interdisciplinary study offered as a ...
For example, cocaine can be detected in the blood for two to ten days, while it can be detected in urine for two to five days. The results of post-mortem toxicology testing are interpreted alongside the victim's history, a thorough investigation of the scene, and autopsy and ancillary study findings to determine the manner of death.

Experiencing fear, extreme stress, or both can cause changes in the body that can, in turn, lead to death. For example, it is possible that overstimulation of the vagus nerve—which decreases heart rate in a mechanism related to the behavior of apparent death (also known as "playing dead" and "playing possum")—is the cause of documented ...
Forensic pathology is a specialized field within forensic science that focuses on the examination of individuals who have died suddenly, unexpectedly, or violently to determine the cause and manner of death. [67] A forensic autopsy is a postmortem examination of the body and analysis of bodily fluids to provide information on the cause of death ...
Vital statistics generally distinguish specific injuries and diseases as cause of death, from general categories like homicide, accident, and death by natural causes as manner of death. Both are listed in this category, as are both proximal and root causes of death. An injury that could be fatal is called major trauma; see also Category:Injuries.
