Welcome to my site! I'm sure you'll find many interesting things to learn about fingerprint identification. You can look at some old cases that were ultimately solved by fingerprint analysis. Fingerprint analysis is very interesting and popular TV crime shows promote it as a very quick and accurate process. At the moment it is not that fast but with the advancements in technology maybe one day it can be as fast and accurate as it is on TV.
Fingerprint impressions fall into three basic types: latent, visible, and the plastic (moulded) prints. By far, the most frequent is the latent print, which is invisible to the eye. Latent prints are formed by sweat, "either from the hands themselves or by unconscious contact between the fingers and the face or other parts of the body". Even the swiftest of criminals find it difficult to escape without leaving behind the trace of a single fingerprint. A variety of techniques, including using chemicals, powders, lasers, and alternate light sources, are employed in the detection and development of prints.
