ABSTRACT
The only accurate method of determining the time of death is observation by a reliable witness. Evaluating the changes that occur in a body after death may help you estimate the time since death, also known as the postmortem interval. Physiological changes since death may be observed at a scene and generally indicate the time since death. Careful observations of these changes should be recorded at the scene and presented to the medical examiner who may be able to determine a far more accurate postmortem interval than could be determined from scene indicators alone.
