Abstract

Fingerprints stands out as the oldest, most used and the most cost-effective method of identification. One of the biggest challenges for its application involves obtaining an adequate register in charred bodies. The thermal action causes destruction in varying degrees of the epidermis and dermis, with skin thinning, hardening, and wrinkling, making it difficult to see the papillary ridges and fingerprints. There are several necropapiloscopic methods available for use in these cases, but as there are particularities in individual cases, the greater the technical arsenal available, the greater the chances of obtaining an adequate record. This report describes the necropapiloscopic technique with indirect light refraction, used to identify a carbonized body. This technique is simple, fast and low cost, which allows its application even in places with little structure. The authors hope that this report will contribute to its use in forensic practice and that it will stimulate studies on it, so that it is technically enhanced.
