Abstract
A method for determining the time period since the death of a human cadaver deposited on soil by the steps of removing a sample of soil from beneath the cadaver, testing the sample for a concentration of a chemical which is indicative of the time since the death of the human cadaver, and correlating the concentration with the number of accumulated degree days (ADD) to determine the length of time since the death of the human cadaver. The chemicals include fatty acids, such as propionic acid, butyric acid, and valeric acid, and inorganic ions, such as ammonium, calcium, magnesium, sodium, chloride, and sulfate.
