“…Thermometry is widely used, as noted by S.J. Jeong et al (2020), the essence of which is to measure the temperature of the corpse at certain points. H. Muggenthaler et al (2012) emphasise the need to correlate the obtained values with tabular data reflecting the dynamics of postmortem cooling for animals of a certain species, weight, etc.…”

Animal cruelty is a criminal offence under the current legislation of Ukraine. When investigating criminal proceedings related to animal cruelty, including domestic cats, it is often necessary to establish the time of death. Therefore, the development of new methods for determining it and improving existing ones is extremely relevant. The purpose of the study was to establish the relationship between the obtained values of wet spot area indicators and the time of death. To achieve this goal, the authors propose a new method for determining the age of death of domestic cats based on the results of measuring the area of a wet spot obtained from skeletal muscle tissue samples of corpses (Shkundia method). To do this, samples of muscle tissue were taken from the corpses of cats, a wet spot preparation was obtained by pressing and its area was calculated to establish a correlation between the values of this indicator and the time that has passed since death. The study of the obtained indicators established that these values are constant, and the features of fluctuations in the values of this indicator with the time elapsed since the death of the animals were established and shown graphically. Using a number of statistical methods, the absence of dependence of wet spot area indicators on the muscles from which samples were taken for research and animal breeds was determined. The nature of changes in the values of the wet spot area indicator depending on time is established and the features of their fluctuations in different periods during 27 days from the moment of animal death were explained. Reference values of these indicators depending on the time elapsed since the death of animals are presented, which can be used by forensic veterinary experts in practical work to determine the time of the occurrence of death of domestic cats. Due to a number of advantages, this method can be widely implemented in the practice of forensic veterinary medicine

“…Compared to other methods of determining the time of death, the advantage of such studies is a long time interval -about 1 month from the moment of death, while thermometry is suitable in the time interval of 1-3 days, which is indicated, for example, by S.J. Jeong et al (2020), microscopic examination -1-18 days, and a method based on determining the state of entomofauna of the corpse, according to J. Byrd & I. Sutton (2021) and S. Matussewski (2021) -no more than 10-15 days. In addition, the equipment required for working with the wet spot method is not difficult to use and expensive, as, for example, for studies using computer or magnetic resonance imaging, which are proposed by E. Watson & J.Kr.…”

“…S.J. Jeong et al (2020), in particular, note that such factors can be climatic components, that is, temperature, humidity and air velocity, the impact of natural phenomena (rain, snowfall, etc. ), the presence of a corpse in the ground, reservoirs, premises, under the rubble of buildings, death in fires and other man-made accidents and catastrophes.…”

“…To estimate correct PMI, currently advanced techniques based on analytical chemistry are applied to obtain data from an entomological and forensic investigation [20]. Diverse methods such as supposition confirming the species after building the sample specimen standard [21], calculating inversely by checking with many factors such as environmental conditions (e.g., the site temperature) [22], and estimating PMI by comparing stages of development with collected storage samples [23,24] have been reported. A method using a constant temperature range related to growth and the base temperature effectively applied to the growth has the problem of over-underestimation of the factor since it is just a measured value [23].…”

Proteomic and Metabolomic Analyses of Maggots in Porcine Corpses for Post-Mortem Interval Estimation

Post-mortem interval (PMI) estimation is a critical task in forensic science. In this study, we used maggots collected from pig carcasses and applied an integrated proteomics and metabolomics approach to determine potential candidate substances for the estimation of PMI. After methanol precipitation, the supernatant containing metabolites and the protein pellet were separated and subjected to metabolomic and proteomic analyses using liquid chromatography-tandem mass spectrometry (LC-MS/MS). MS/MS data were analyzed for identification and quantification using Proteome Discoverer and Compound Discoverer software. A total of 573 metabolites and more than 800 porcine proteins were identified in maggots. This is the first dataset of proteins and metabolites in maggots collected from porcine carcasses. In this study, guanosine monophosphate, xanthine, inosine, adenosine, and guanine were detected with a similar tendency to increase during early days of maggot development and then decreased gradually. We broadly profiled various biomolecules through analysis in the spot of incident. Especially, we confirmed that proteome and metabolome profiling could be performed directly and indirectly.
