“…Bates and Wescott [41] reported no significant difference in the rate of decomposition between autopsied and non‐autopsied cadavers in central Texas, USA. Baigent et al [42] reported decomposition rate did not differ between autopsied and non‐autopsied subjects at their donor facility in Colorado, USA. Our study supported these findings in terms of the effect of autopsied cadavers might have on under‐ or over‐estimations for postmortem interval.…”

Estimating postmortem interval (PMI) of surface found skeletal remains is challenging. This novel study used UV-Vis-NIR spectroscopy to scan soil collected from cadaver decomposition islands (CDIs) ranging from 15-to 963-d postmortem and control soils. A decomposition product spectra model (DPS model) was constructed by deducting the control soil spectra from the CDI soil spectra for the estimation of postmortem indices: PMI (d), ADD 4 , ADD 10 , and ADD 20. The DPS model (n = 55) was calibrated and subjected to a full cross-validation. Calibration R 2 and RPD for the DPS model ranged from 0.97 to 0.99 and from 6.1 to 9.9, respectively, for the four postmortem interval indices. Validation R 2 and RPD for the DPS model ranged from 0.73 to 0.80 and from 1.9 to 2.2, respectively. The DPS model estimated postmortem intervals for three test CDIs in a clay soil under perennial grassland (test set 1; n = 3) and six CDIs in a sandy soil under a loblolly pine forest (test set 2; n = 6). Test set 1 had PMI prediction ranges from −69 to −117 days, −796 to +832 ADD 4 , +552 to +2672 ADD 10 , and −478 to −20 ADD 20 of observed PMI. Test set 2 PMI prediction ranged from −198 to −65 days, −9923 to +2629 ADD 4 , −6724 to +1321 ADD 10 , and −2850 to +540 ADD 20 of observed PMI. Test set 2 had poor predictions for two CDIs, for all measures of postmortem indices resulting in discussion of sampling depth, effect of body mass index (BMI), and scavenging.

“…Los fenómenos cadavéricos tardíos de destrucción son aquellos que se consideran como una evolución natural que culmina con la destrucción del cuerpo humano, estás señales aparecen en un periodo de tiempo menor de entre las 24 a 36 primeras horas de ocurrida la muerte, y la evolución de estos se influencia directamente de las propiedades del cuerpo como masa muscular, tejido adiposo, ropa presente en el cadáver, posición de ISN 2707-2207/ISSN 2707-2215 (en línea), enero-febrero, 2023, Volumen 7, Número 1 p 2499 muerte, causa de muerte y factores ambientales (17,26,29).

Al hablar de los fenómenos cadavéricos como tal, se hace referencia y agrupa todo el proceso en el que se maneja a un ser humano fallecido, desde los primeros minutos en los que muere, tomando en cuenta los signos que permiten determinar y calificarlo como un cadáver, las causas de su descenso y el proceso legal en caso de ser victima de violencia o causas desconocidas, o la debida preparación del cuerpo por parte de los expertos en el tema, a fin de identificar aquellas señales que forman parte del ciclo del fenómeno cadavérico debidamente llamado. Es así, que la investigación desarrolla por Solano (2010), establece que existe un debido manejo del escenario de la muerte y el proceso de la autopsia medica necesaria en caso de determinar que el fallecimiento se da por causas no naturales, como actos de violencia, suicidio, o causas desconocidas que ameritan un estudio legal que determine el motivo del mismo, en esta escena la intención principal de los encargados y profesionales es describir con claridad el crimen, ambiente y observaciones tanto ambientales del lugar para posterior a ello realizar el estudio físico y biológico del cadáver a fin de esclarecer las causas por las que se produce el descenso y registrar los fenómenos cadavéricos que van apareciendo durante la sesión. De esta forma, a lo largo de la presente investigación se detallará y conceptualizara a los fenómenos cadavéricos, etapas y el proceso de tanatocronodignóstico que permite determinar el tiempo de fallecimientos, las principales señales y signos que corroboran la muerte de la persona, poder identificar las posibles causas y el tratamiento que se da durante el estudio bioquímico y toxicológico del cuerpo.

“…It may also hinder the determination of the cause and manner of death [5,31]. The effects of penetrating trauma and evisceration on the rate of decomposition have been studied by several authors [32][33][34]. According to Mann et al [32], trauma influences the decomposition rate, speeding up the process.…”

“…According to Mann et al [32], trauma influences the decomposition rate, speeding up the process. In contrast, other authors observed that trauma affects the pattern of decomposition but not the rate [33,34]. Either way, dismemberment complicates the estimation of the post-mortem interval, as the visual evaluation is less accurate when an incomplete cadaver is in an advanced state of decomposition [35,36].…”

Dismemberment as a Method of Body Disposal in Spanish Forensic Cases

This study provides an overview of victim and offender data, the cause and manner of death, the dismemberment type, the post-dismemberment alteration, and the forensic investigation, for 35 Spanish forensic cases. The main aim of this study was to perform a retrospective analysis of dismemberment and body part alteration in Spain since 1990, in particular relating to burning. The sample was selected from a Spanish national database on criminal records (CENDOJ). Official court records were examined for 96 variables, which were analysed through non-metric multidimensional scaling analysis (nMDS). The results obtained revealed that the number of dismemberment cases between 1990 and 2016 totalled 35 (amounting to a total of 40 bodies) with an incidence of 0.29% of the total number of homicide cases in the database. Most of the aggressors were Spanish adult males, and the victims were adult females of foreign nationality. The most commonly employed tool used to kill and dismember was the knife. A total of 15.00% of the 40 bodies were further altered by fire. It was concluded that dismemberment and other postmortem actions contributed to complicating the forensic investigation and hindering the identification of the deceased.
