The creation and features of a regional decomposition scoring system for western Colorado are outlined as a model for the development of regional systems.
Abstract
The development of such a scoring system requires: (1) human remains, not proxies, (2) longitudinal observations, and (3) large sample size. First, an enhanced system (total body desiccation score [TBDS] ) was developed through observations of 40 human remains. This effort produced a categorical scoring model augmented by qualitative categories of gross tissue change. The new model was tested with retrospective photographic packets. A sample of eight donors with data collected over 3 years was selected. Monthly data points over a maximum of a 3-year period yielded 112 data points. Correlations between TBDS and accumulated degree-days (ADD ), and total body score (TBS ) and ADD were approximately equal for a TBS below -20, but the TBDS correlated better with ADD at higher TBS scores >20. The TBDS may be used to refine postmortem interval (PMI ) models in areas where remains desiccate. (publisher abstract modified)
