The DS Method for Evidence Characterization
HR Lukens, DE Bryan · Journal of Forensic Sciences · 1974
Abstract The scientific comparison of materials is often used as an aid to assigning responsibility for infractions of the law. A suspect, for example, may (or may not) be linked to the scene of a crime, depending on whether his hair matches (or does not match) hair found at the scene. The confidence in conclusions reached by such comparisons depends on the number of measured characteristics and the manner in which such characteristics vary among both the universe of such material and the appropriate subset; for example, the variance of hair among humans and the variance of hair on a single human.
