Post-mortem photography is the practice of photographing the recently deceased. Various cultures use and have used this practice, though the best-studied area of post-mortem photography is that of Europe and America. [1] There can be considerable dispute as to whether individual early photographs actually show a dead person or not, often ...
The post-mortem interval (PMI) is the time that has elapsed since an individual's death. [1] When the time of death is not known, the interval may be estimated, and so an approximate time of death established. Postmortem interval estimations can range from hours, to days or even years depending on the type of evidence present. [2]

These changes can generally be divided between early post-mortem changes and late post-mortem changes (also known as decomposition). [12] These changes occur along a continuum and can be helpful in determining the post-mortem interval, which is the time between death and examination. The stages that follow shortly after death are:
Putrefaction is the fifth stage of death, following pallor mortis, livor mortis, algor mortis, and rigor mortis. This process references the breaking down of a body of an animal post-mortem. In broad terms, it can be viewed as the decomposition of proteins, and the eventual breakdown of the cohesiveness between tissues, and the liquefaction of ...
