Abstract :

Fingerprints are one of the most common types of evidence found in crime scenes. On the other hand, due the surfaces where they can be deposited, fingerprints are not always easy to visualize. This paper aims to expose a research done in London with a new chemical: Lumicyano. Visualization of fingerprints on clothing can be important in contact crimes as murder and rape to prove that offender was in contact with at least the piece of garment from victim. In order to understand if it was possible to visualize fingerprints with Lumicyano on clothing, 13 types of fabrics were tested and analyzed in black and white colors. Samples were chosen taking in account the most common types of fabrics used in London├ó┬?┬?s population. Results were analyzed at naked eye but also with fluorescent lights; that revealed in some cases fingerprints with high quality detail. With more than 130 samples of fabrics analyzed, it was possible to conclude that this is a suitable technique to visualize fingerprint on garment. Dark samples obtained better results but in some white samples it was also possible to observe some details. This study aims to increase knowledge on the possibilities of visualizing fingerprints in porous surfaces which are usually more difficult to observe.
