Estimating the Post-Mortem Interval of skeletonized remains: The use of Infrared spectroscopy and Raman spectro-microscopy

When skeletonized remains are found it becomes a police task to determine to identify the body and establish the cause of death. It assists investigators if the Post-Mortem Interval (PMI) can be established. Hitherto no reliable qualitative method of estimating the PMI has been found. A quantitative method has yet to be developed. This paper shows that IR spectroscopy and Raman microscopy have the potential to form the basis of a quantitative method.
