postmortem interval

The estimated number of hours, days, weeks, or months between the discovery of a cadaver and the time of death. Forensic scientists use a variety of techniques to make this determination, e.g., evidence of changes in body temperature, muscular rigidity, blood pooling, and bodily decomposition. Infestation by insects with known larval or pupal developmental stages provides valuable information when forensic scientists are examining bodies that have been dead for a long time.
