Determination of the exact time of death of a human being or animal is extremely important for investigations conducted by law enforcement agencies. The development of a single model of tests and analysis of the site of the incident would be a breakthrough for forensic and veterinary medicine in estimating the exact time of death. Microorganisms play a key role in the putrefaction process. Each stage of decomposition is characterized by the colonization of tissues by different microbial taxa. The objective of the study was to determine the suitability of microbiological tests for establishing the time of death, using the example of the gastrocnemius muscle in a dog (German Shepherd). The results of the study showed that sporulating aerobic bacteria of the species Bacillus cereus, as well as anaerobic bacteria, played a major role in the putrefaction process. No E. coli were found in the material. The first bacterial colonies belonging to the Bacillus cereus group were observed on the 7th day after the death of the animal, and their quantitative growth persisted throughout the study period, i.e. until the 21st day after death. The analysis carried out in this study shows that Bacillus cereus bacteria appear much sooner than anaerobic bacteria.

Post Mortem Examination and Autopsy - Current Issues From Death to Laboratory Analysis

View full text Add to dashboard Cite

The identification and individualization of biological evidences is crucial to actual criminal investigations. In spite of the differences at the national level, all the legal processes attribute particular importance to forensic DNA analysis. However, none of the qualified results from any professional laboratory can produce substantive, valuable evidence with insufficient quality of samples and/or problems with provision of a pristine and controlled environment. The methodology and efficiency of sampling are distinct in case of living persons and in medico-legal autopsy and crime scenes. This chapter is a short overview from the basic introductory information up to ongoing research, and in accordance with constraints on the chapter size, it briefly discusses the important topics of sample collection at medico-legal autopsy for DNA analysis. The content sorts the major types of samples, reviews the common methods of sampling and the potential risk of poor sampling or contamination transfer. The corpses can be more or less degraded, which in special cases (e.g., paraffin embedded tissues, drowned, burning and/or buried cadaver) allow only for analysis of highly degraded samples. The samples can be associated with tissues of a corpse (e.g., blood, soft tissues, bone, tooth, hair) and/or additional extraneous tissues and remains, which are often mixed (e.g., blood, saliva, semen, vaginal fluid, debris of fingernails) on the corpse.

“…Also important for the putrefaction gases hypothesis is the temperature, as putrefaction rates decelerate with decreasing temperature (Bonhotal et al 2006;Dickson et al 2011;Robinson et al 1953). The water temperature at the bottom of the epeiric sea in which the Posidonienschiefer accumulated is not known, but the surface-water temperature has been estimated to have fluctuated between 25 and 30°C (Röhl et al 2001).…”

Ichthyosaur embryos outside the mother body: not due to carcass explosion but to carcass implosion

Some well-preserved ichthyosaurs found in the Early Jurassic Posidonienschiefer Formation at Holzmaden (Germany) have puzzled palaeontologists for a long time: their skeletons are exceptionally well preserved and their bones are almost all in situ, but the bones of their embryos are scattered, partly beyond the body limits of the mother. This has been explained initially by bottom currents and later by a displacement of already disarticulated embryos during the expulsion of putrefaction gases through the disrupted body wall of the mother. It was postulated recently that this latter hypothesis is not tenable. It is argued here that both hypotheses are not tenable in their original form, but that carcass implosion may explain the various enigmatic features.
