     University of Jerusalem. Our goal is to
     improve the understanding of the
     reaction mechanism.
     Three main aspects are being
     examined:
     • First, focusing on the interaction
       between an iron surface and the palm
       of the hand. How does the iron
       attach to the skin? What parameters
       influence the presence of iron on the
       palm?
     • Second, focusing on the reaction
       between iron and PDT. What are the
       optimal conditions? And what are the
       detection limits?
     • Third, investigating the absorption
       mechanism of iron on the palm skin.
       How long after the contact will the
       suspect give a visible sign?
     All three directions are not new, yet
     not much scientific work had been
     accomplished until now.
     Preliminary results indicate a
     correlation between the development
     of latent fingerprints and good firearm
     imprints on the hands. We assume that
     as the amount of sweat increases, a
     better magenta mark develops. The
     firearm’s rust and holding duration
     affects the imprints as well. So far,
     most questions remain open. However,
     by collecting enough information from
     many individuals, we hope to get some
     answers and improve the detectability
     of the marks and hence, improve the
     detective’s work where there is “no
     smoking gun”.
