Annotation: This paper describes the vapor phase fuming of latent fingerprints with dimethylaminocinnamaldehyde (DMAC) and notes that this technique provides good visualization of ridge details on a wide selection of substrates and can be included in routine sequential examination procedures.
Abstract: The visualization of latent fingerprints produced by vapor phase fuming is often desirable due to its often nondestructive characteristic; fuming techniques vary in their effectiveness. In the work reported here, fuming experiments were initially carried out on fingerprints from several donors who laid down a mixture of sebaceous and eccrine-sweat-rich materials on white paper and polythene. The prints were aged for 5 days at ambient temperature and humidity before fuming. The results revealed the usefulness of DMAC, which has particular promise as a reagent for visualizing marks on fax papers, a substrate that has previously been problematic.
