Mummification is an alternative to human decomposition that involves desiccation of the tissues of the body, particularly the skin. A total of 44 decedents with known postmortem intervals (PMIs) were collected from the Maricopa County Medical Examiner's Office and given a cumulative mummification score (CMS) describing the extent of their mummification using a novel scale. PMI was multiplied by the ambient temperature of the scene to allow for the creation of a new variable, accumulated degree days (ADDs). A non-linear relationship was found between PMI and ADD.
