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]
t. e. Timeline of postmortem changes, with algor mortis represented by red temperature line. Algor mortis (from Latin algor 'coldness', and mortis 'of death'), the third stage of death, is the change in body temperature post mortem, until the ambient temperature is matched. This is generally a steady decline, although if the ambient temperature ...
These changes can generally be divided between early post-mortem changes and late post-mortem changes (also known as decomposition). 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:
This can help with the post-mortem interval identification by looking at the stage of digestion. The contents can also be analyzed for drugs or poisons to help determine a cause of death if it is unknown. Post-mortem Diagnosis. Post-mortem diagnosis is the use of post-mortem chemistry analysis tests to diagnose a disease after someone has died.
Corpse decomposition. Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
Calliphora vicina is known as a blue bottle fly because of the metallic blue-gray coloration of its thorax and abdomen. It is distinguished from the commonly known C. vomitoria by its bright orange cheeks. The blue bottle fly is approximately 10–11 mm in length. The sclerites at the base of the coxa are yellow or orange.
Depiction of a body after suicide hanging. Livor mortis is fixed in the legs and distal upper extremities because these were the dependent parts. Livor mortis ( Latin: līvor – "bluish color, bruise", mortis – "of death"), postmortem lividity (Latin: postmortem – "after death", lividity – "black and blue"), hypostasis ( Greek: ὑπό ...
