Abstract

Estimation of the time since death is one of the most important problems in forensic cases. It is relatively easier to estimate the time since death in such cases if the corpse is fresh or the soft tissue still exists. However, estimating postmortem interval becomes more complicated as decomposition stage of the corpse develops. While evaluating decomposition stages of a corpse, different criteria like environmental conditions, position of the body and bodily features should be studied all together. Estimation of the time since death is carried out macroscopically in the first place according to morphological changes. Nevertheless, various histological, chemical and psychical methods can be used as well to estimate the time since death particularly if long time passes after death and skeletonization begins. Of all these methods, radioisotope analyses are the most discussed method since it is not affected by environmental factors. Because of their short half-lives, the analyses especially carried out with measurement of Srand Pbradionuclides have produced successful results in estimating postmortem intervals.

Özet

Ölüm zamanı tayini adli olgularda en önemli sorunlardan biridir. Cesedin taze olduğu veya yumuşak dokusunun henüz mevcut olduğu durumlarda ölüm zamanını tespit etmek nispeten daha kolaydır. Ancak cesetlerin dekompozisyon seviyesi ilerlediğinde veya iskeletleşme gerçekleştiğinde ölüm zamanı aralığını tespit etmek daha komplike bir hale gelmektedir. Cesedin dekompozisyon aşamaları değerlendirilirken çevresel şartlar, cesedin bulunduğu konum ve cesedin beden özellikleri gibi farklı kriterlerin birlikte incelenmesi gerekir. Ölüm zamanı tayini öncelikle makroskobik olarak morfolojik değişimlere göre yapılmaktadır. Ancak, özellikle ölümün üzerinden uzun süre geçtiği ve iskeletleşmenin gerçekleştiği durumlarda çeşitli histolojik, kimyasal veya fiziksel yöntemler de ölüm zamanının tespit edilmesinde kullanılabilir. Bu yöntemlerden radyoizotop analizleri, çevresel faktörlerden etkilenmemesi bakımından en çok üzerinde durulan yöntemler olmuştur. Yarılanma ömürlerinin kısa olması sebebiyle özellikle Sr ve Pbradyonüklidlerinin ölçümleri ile yapılan analizler ölüm zamanı aralığının tespitinde başarılı sonuçlar vermiştir.
