“…If the victim’s identity was found in the system, the screen containing the identification information would be photographed. If there was not any match, attempts were made toward skin reconstitution by injecting glycerine [ 11 ] or boiling treatment [ 12 ]. Then, fingerprints were collected once more using the biometric reader and, in case of another negative result, ink and a fingerprint card were used.…”

Depending on the magnitude and nature of a disaster, identifying the victims can be a complex task that requires coordinated work by disaster victim identification (DVI) teams based on pre-established protocols. Thus, the analysis of fingerprints has been presented as a method to establish, when possible, the identity of the victims during the DVI process. This study discusses the importance of this primary method of identification and the results obtained in four different disasters in which Brazilian DVI teams were involved: the Air France Flight AF447 plane crash in the Atlantic Ocean, floods and mudslides in the State of Rio de Janeiro, Brazil, the LaMia Flight 2933 plane crash in Colombia, and the tailings dam collapse in Brumadinho, Brazil. Here, we also report the use of the automatic fingerprint capture and identification system, called Alethia, developed by the Federal Police of Brazil and used in the victim identification process in the two latter events mentioned above. KEY POINTS• This article presents four different disasters that occurred in Brazil and overseas and involved Brazilian DVI teams in the identification process, focusing on fingerprint identification (Air France Flight AF447, floods and mudslides in the State of Rio de Janeiro, Brazil, LaMia Flight 2933, and the Brumadinho tailings dam collapse). • This article also describes the evolution of the DVI process in Brazil, including a description of the technology currently used by Brazilian fingerprint experts (Alethia). • This article reports how the Alethia System was used in the disasters and how it optimized the human identification process when compared to traditional methods.

“…O conjunto de técnicas descritas neste trabalho permite a utilização tanto da epiderme como da derme na obtenção do registro datiloscópico. Está bem estabelecido que o desenho datiloscópico dérmico apresenta basicamente as mesmas características do epidérmico, apesar do registro obtido pelo último apresentar maior precisão no confronto [14,15]. Com isto, será maximizado o uso dos desenhos digitais disponíveis.…”

Os principais métodos de identificação de um cadáver desconhecido são o datiloscópico, o odonto-legal, o antropológico e o genético (DNA). Destes, o datiloscópico destaca-se como o mais antigo, o mais utilizado e o de melhor custo-benefício. Um dos desafios na identificação datiloscópica envolve a obtenção de um registro adequado em idosos. A idade avançada faz com que os desenhos digitais se apaguem e a epiderme delgada dificulta a coleta de forma padrão. Vários são os métodos necropapiloscópicos disponíveis para uso nestes casos, mas, como há particularidades em casos individuais, quanto maior o arsenal técnico disponível, maiores as chances de obtenção de um registo adequado. Neste relato é descrita a técnica por vesicação com alta temperatura, que permite a utilização tanto da epiderme como da derme na obtenção do registro datiloscópico. Esta técnica é simples, rápida e de baixo custo, o que permite sua aplicação mesmo em locais com pouca estrutura. E também pode ser realizada em quaisquer casos nos quais haja o apagamento das cristas e sulcos interpapilares. Outra vantagem é não necessitar da remoção do dedo a ser utilizado, minimizando a manipulação e a deformação cadavérica. Os autores esperam que a divulgação desta técnica contribua para sua utilização na prática forense e que estimule estudos sobre ela, para que seja aprimorada pela percepção e correção de eventuais problemas técnicos.

“…It is widely accepted that the pattern of a fingermarks can be described at three levels of detail [15]. The level 1 features describe the general type of the fingermarks, such as a loop, a whorl or an arch [16]. The level 2 features are used to describe characteristic minutiae of fingermarks and usually includes start point, end point, intersection and bifurcation of the fingermark.…”

The electrochromic detection of latent fingermarks on polished or unpolished, flat or curved metal surfaces is described using electrochromic material, 1,1'dibenzyl-4,4'-bipyridinium dichloride. The surface area covered by fingermarks acts as an insulating mask, causing 1,1'-dibenzyl-4,4'-bipyridinium dichloride to change color and produce inversed images of the fingermark. By changing the applied potential, the optical properties of 1,1'-dibenzyl-4,4'-bipyridinium dichloride can be continuously and reversibly adjusted to optimize the visual contrast of fingermarks, so as to realize the detection of latent fingermarks on stainless steel surface. It is demonstrated that the fabricated electrochromic devices can detect the fingermarks on these types of surfaces within twenty seconds at À 1.0 ~À 2.0 V. This work can qualify as a tangible improvement in fingermark detection of the natural fingermarks on the never-cleaned (more than 3 years) and curved surfaces of daily-used container, e. g. cup, and the handle of cleaning tool, mop.
