Morphological trace evidences such as toolmark, footprint, bloodstain patterns and fingerprints have an important role to solve crime by estimating criminal tools and suspects and reconstructing crime scenes.
We made a database system about tools and deadly weapons and developed standard operational procedures(SOP) about the estimation method of toolmarks and analysis techniques of footprints. We developed a statistical decision method of the identity of three dimensional striation marks of toolmarks using three dimensional microscope and cross correlation. We developed the apparatus to estimate the area of origin of impact spatter and applied for a patent.
By applying developed SOP, a patent and research results, we will more invigorate the field of morphological trace evidence analysis. As a result, it is expected. to apply more systematic method to analyze morphological trace evidences.
