Paper Abstract

The U.S. Secret Service has been doing and supporting research in several areas of fingerprint visualization. The following is discussed: (1) developing ninhydrin analogues for visualizing latent prints on porous surfaces such as paper (with Dr. Madeleine Joullie, University of Pennsylvania); (2) exploring reflective UV imaging techniques as a no-treatment-required method for visualizing latent prints; (3) optimizing 'gun bluing' methods for developing latent prints on metal surfaces (such as spent cartridges); (4) investigating aqueous metal deposition methods for visualizing latent prints on multiple types of surfaces; and (5) studying methods of transferring latent print residues onto membranes.
