Abstract

Determining the post-mortem interval (PMI) is often a very demanding and delicate job which requires a good knowledge of postmortemchanges. In this study, 20 domestic pig carcasses (Sus scrofa) whose death occurred within 8 h before the start of the study were simultaneouslylaid at the same geographical location, but in different environments (on the ground surface - S; buried in the ground - G; placed in a crateand buried in the ground - C; submerged in water - W; and hanging in the air - A). One carcass from each group was sampled on days 14,28, 120 and 190 from the beginning of the experiment, and on that occasion, a detailed analysis of postmortem changes and an autopsywas carried out. The difference in the rate of decomposition among groups was statistically significant. The fastest decomposition occurredin carcasses placed in a crate and buried, because during the winter period the temperature in the air was below 0°C. At that time, thedecomposition process and the insect activity were slowed or stopped on carcasses in groups S, A, W, and G to some extent, while the groundand wooden crate were good thermal insulators for group C carcasses and provided better conditions for insect activity

Özet

Ölüm zamanını belirlemek çoğu zaman zor ve hassas bir iş olup postmortem oluşan değişiklikleri bilmeyi gerektirir. Bu çalışmada ölümleri 8 saat içerisinde gerçekleşmiş 20 adet evcil domuz (Sus scrofa) karkası aynı zamanda ve aynı coğrafik lokasyonda fakat farklı ortamlarda (toprak yüzeyinde (S), toprağa gömülü (G), tabut içerisinde toprağa gömülü (C), su içerisinde (W), havada asılı (A)) tutuldu. Her gruptan bir karkas çalışmanın başlandıcından sonra 14, 28, 120 ve 190. günlerde alınarak postmortem değişiklikleri belirlemek amacıyla analiz edildi ve otopsileri gerçekleştirildi. Gruplar arasındaki dekompozisyon oran farkları istatistiksel olarak anlamlı bulundu. En hızlı dekompozisyon, kış süresince hava sıcaklığının 0°C altında olması sebebiyle tabuta yerleştirilerek gömülenlerde oluştu. Bu sürede dekompozisyon süreci ve böcek aktivitesi S, A, W ve G gruplarındaki karkaslarda bir seviyeye kadar yavaşladı veya durdu. Toprak ve tahta tabut iyi bir ısı yalıtımı görevi görerek grup C’deki karkaslarda böcek aktivitesi için daha uygun şartlar sağladı.
