Criminalystic: effectiveness of lysochromes on the developing of invisible lipstick-contaminated lipmarks on human skin. A preliminary study.
|
| Abstract |
Latent prints are an important evidence for identification. Nowadays, the technical means, the implementation of image processing techniques and the use of database makes it possible to detect and get information from some prints that seem to be useless at first sight. On the other hand, the possibility of using the print as a DNA source has to be considered, so as to double its identifying value. Human skin is a particularly difficult surface for developing this kind of evidences. Although different methods for locating and developing latent fingerprints on the skin have been already described, it has not been found any method, at the revised bibliography, to obtain and develop invisible lipmarks, that is, lipmarks from protective lipstick, or permanent or long-lasting lipstick. The aim of the work that follows is to determine the effectiveness of several reagents for developing invisible lipmarks on the corpses' skin. Preliminary results show that, under the described experimental conditions, the reagents used, Sudan III, Oil Red O and Sudan Black, are effective for obtaining recent latent lip prints on corpse's skin.
