Abstract
A method for locating human remains in a clandestine or undocumented burial includes providing a spectroscopy assembly including a spectroscopy probe with a distal end to a location that may include human remains, wherein the spectroscopy assembly is configured to identify whether a salt of a fatty acid is present based on overtone wavelengths of the salt of the fatty acid; inserting the distal end of the spectroscopy probe into a testing spot at the location that may include human remains; and analyzing, with the spectroscopy assembly and after the step of inserting, whether the salt of the fatty acid having the overtone wavelengths is present in the location that may include human remains. The step of analyzing may include near-infrared spectroscopy, and the overtone wavelengths may be characterized by an absorption band contour extending from about 1670 nm to about 1800 nm.
