Analysis of touched DNA from crime scenes is fundamental in forensic DNA laboratories. Many factors affect the recovery of DNA from touched surfaces and then affect the quality of the final results. The aim of this work is studying the possibility of recovery suitable amount of DNA from ltouched portable computer. The computer was cleaned with 10% Bleach then touch and DNA collected for extraction by Organic method and two STR regions D5S818 (115-163bp) and FGA (308-464bp) were amplified. The results showed that it is possible to isolate a proper amount of DNA from touched portable computer where it was amplified and then analyzed by Agarose gel electrophoresis. The conclusion is that portable computer is suitable source for forensic analysis.
Following suicide bombing, human remains usually collected for DNA identification. Human remains affected due to exposure to excessive heat and bomb solid, sharp pieces. The aim of this work is to study the possibility of DNA analyzing of human remains after suicide bombing. Fifteen human remains were received from a place of suicide bombing in Najaf City south of Iraq. The remains were severely affected and cannot recognize morphologically or as it is human or animal origin. DNA extracted from remains by organic method, then quantified by real time PCR kit then analyzed by Powerplex 21 kit using 3130XL Genetic Analyzer. The results showed that seven remains where analyzed successfully while the other remains failed for analysis for both real time PCR quantification or STR analysis. Four remains belong to two persons. This study showed that suicide bombing affects negatively the most remains for STR analysis.
