This paper describes a research project aimed at minimizing the human and environmental factors that influence forensic analysts’ ability to obtain consistent and reproducible fingerprint impressions from common biofluids encountered at crime scenes.
In an effort to minimize human and environmental factors associated with the deposition of impression evidence researchers can utilize optimal deposition parameters to generate consistent reproducible impressions for analysis. The deposition parameters defined in this study provide a guideline for producing optimal fingerprints deposited in common biofluids (eccrine/sebaceous sweat, non-human oil, blood, semen and saliva) onto a variety of substrates encountered at crime scenes. Optimal quality impressions can be used as a control in depletion or dilution series to test the effectiveness of new products conduct chemical and physical enhancement trials as well as to validate enhancement methods for laboratory use.
