During the reconstruction of a shooting incident, several analytical techniques are at the disposal of forensic scientists. The Netherlands Forensic Institute is exploring the opportunities in which mXRF can be used to obtain information in these reconstructions. In this paper the possibilities of using the 2D-mXRF instrument as a screening tool are explored. Primarily the focus is on using mXRF to obtain information regarding the elemental composition of gunshot residue from cartridge cases. Secondly, the possibilities of using the 2D-mXRF instrument to, quickly and easily, set up databases for gunshot residue analysis are investigated.
The investigation of garment and human tissue originating from a victim of a shooting incident can provide crucial
information for the reconstruction of such an incident. The use of 2D-mXRF for such investigations has several
advantages over current methods as this new technique can be used to scan large areas, provides simultaneous
information on multiple elements, can be applied under ambient conditions and is non-destructive. In this paper we
report our experiences and challenges with the implementation of 2D-mXRF in GSR analysis. Currently we mainly
focus on the use of 2D-mXRF as a tool for visualizing elemental distributions on various samples.
