The necropsy is one study carried a corpse in order to investigate and determine the causes of death, generally, the term used as a synonym for autopsy, because in both cases we proceed to the study of corpses, however, It can be stated that the necropsy is used in the area of criminology more than in any other branch of the investigation since the necropsy includes everything related to the place of the fact, everything concerning the evidence and tools that were used to carry out the murder and its subsequent lifting of the place.
The necropsy can also include the dissection of the body, since in some cases the reasons why the event occurred is not seen with the naked eye. The etymology of the word indicates that it comes from the combination of Greek " Nekrós " which means " Corpse " and " Opsis " referring to " Observe ", however, this gives us to understand that the necropsy in addition to being a process of visualization, it is also a complete analysis in which investigation parameters are established so that the scene is always kept clean, just as it was from the moment of the death of the person. The causes of death can be sufficiently clarified with the environmentin which the body is found, the search for clues, DNA and any indication that leads to the materialization of the crime can lead to much more than a simple scene, at the necropsy all kinds of samples, photos, and objects are taken as evidence in order to analyze the necropsy more elaborately.
Regarding necropsies, we also find an interesting topic, there are cultures, religions or foci of society that prevent the dissections of the corpses, considering it an offense to any deity that they praise. There are societies with extreme beliefs that protect rituals for the dead, so the authorities in certain cases respect this and prevent a necropsy from being carried out, however, in cases of public security, these customs must be suppressed by the measures that must be carried out. For the good of all. This opens a really extensive chapter of clash between cultures.
