“…The difference between the species composition of adult versus larval stages was obvious. To a certain extent, this is not surprising, as numerous succession studies have shown a higher number of species among the adult specimens sampled on or near the carcasses, compared with the larval stages actually developing on the cadaver [45][46][47]. This can partly be explained by sampling artifacts, within the respective studies (not enough time, etc.…”

A field study to evaluate PMI estimation methods for advanced decomposition stages

Estimating the postmortem interval (PMI) is one of the major tasks and a continuous challenge in forensic pathology. It is often an exclusion process of available methods, which ultimately can lead to an unsatisfactory outcome due to poor reliability. This problem is most acute in the late PMI, when decomposition proceeds and some methods (such as rigor, livor, and algor mortis) are no longer applicable. Several methods, such as forensic entomology, skeletal muscle protein degradation, and the study of body decomposition by application of a morphological scoring, are expected to provide further information; however, all have certain limitations and weaknesses. Availability of a toolbox of methods allows a case-specific selection of the most appropriate one(s), or eventually provides improvements in the overall accuracy and precision of the PMI estimation by merging and combining methods. To investigate practical (field) application, eventual interferences, and/or synergetic effects, as well as the robustness of these methods towards specific influencing factors, a field study was conducted, using eight pig cadavers of different body weights and physical coverage, left to decompose under natural conditions for 16 days. Morphological changes during decomposition were assessed using the total body score (TBS), muscle samples were collected to analyze protein degradation, and insect colonization was evaluated. The results reveal strengths and current limitations of all tested methods, as well as promising synergistic effects, and thus, provide a baseline for targeted future research.

“…In the Iberian Peninsula, there are reports of the contributions to the knowledge of the structure and dynamics of the entomosarcosaprophagous fauna in several areas (i.e., [ 7 , 9 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]), and, in at least one case [ 14 ], a relationship between experimental study and forensic cases’ resolution has been established. Moreover, studies on certain groups of insects have addressed the morphology of immature stages [ 27 , 28 , 29 , 30 ] and the development of certain species under controlled conditions (i.e., [ 31 , 32 ] among others).…”

The aim of this work is to present a number of forensic cases that took place in Southeastern Spain (Murcia province) in which the entomological evidence aided to fully solve the issues raised during the legal enquiry, enhancing the close interrelationships between experimental studies performed and actual forensic cases assessed. In all cases, the expert report was requested by the police agents or the medical examiners, the latter attempting to make stronger their own conclusions. The assessment of all cases was possible by comparing the evidence and circumstances of each one with the experimental data previously obtained in our laboratory concerning aspects such as faunistic, ecological, morphological, etc., and by considering data from other researchers. In all cases, the evidence could be addressed, although in some cases, it had not been properly collected or processed. Thus, the utility of the experimental studies in forensic practice, even when being considered merely biological, and without immediate practical application, can be demonstrated as well as the need for providing specialized instruction on Forensic Entomology procedures to the different agents involved in forensic investigation.

“…Las comunidades sarcosaprófagas están compuestas principalmente por artrópodos, generalmente ácaros e insectos (Tantawi et al, 1996;Saloña-Bordas & Perotti, 2015). A su vez, la entomofauna sarcosaprófaga está representada por un gran número de especies de dípteros, coleópteros e himenópteros necrófagos y necrófilos que acuden a la carroña de manera secuencial y relativamente ordenada según la etapa de descomposición que atraviesan los restos (García-Rojo, 2004;Salazar-Ortega, 2008;Baz et al, 2014;Zanetti et al, 2015;Pérez-Marcos et al, 2017;Díaz-Aranda et al, 2018;Martín-Vega et al, 2019). Los dípteros son colonizadores primarios que tienden a aparecer en etapas tempranas del proceso de descomposición.…”

“…Estas fueron encontradas en restos secos de mamíferos domésticos y silvestres en entornos periurbanos y naturales. Los resultados obtenidos coinciden en líneas generales con los aportados previamente en la literatura (Español, 1959;Martín-Vega et al, 2019;Cabanillas, 2020). La familia Dermestidae estuvo compuesta por cinco especies necrófagas, las cuales tienden a aparecer en fases avanzadas del proceso de descomposición para alimentarse del tejido fibroso de los restos secos (Díaz-Aranda et al, 2018;Cabanillas, 2019;Martín-Vega et al, 2019).…”

Con el objetivo de ampliar la distribución conocida y el conocimiento ecológico de las especies sarcosaprófagas con potencial interés forense en la península ibérica, se recopilan 758 nuevos registros correspondientes a 105 especies de coleópteros, dípteros e himenópteros en 43 provincias españolas y 4 distritos portugueses. Se registran un total de 89 primeras citas provinciales y se aportan numerosas localidades inéditas que permiten ampliar el rango de distribución conocido de la entomofauna sarcosaprófaga ibérica. Entre los resultados más relevantes destaca la expansión territorial de los dípteros alóctonos Chrysomya megacephala (Fabricius, 1794) y Hermetia illucens (Linnaeus, 1758) en la península ibérica. Además, se documentan hábitos sarcosaprófagos por primera vez en el formícido Hypoponera eduardi (Forel, 1894). Finalmente, se discuten los resultados ecológicos obtenidos en relación a las comunidades sarcosaprófagas y su potencial interés en estudios forenses.
