Vrednovanje analize DNA u predmetima vještačenim prije uvođenja tehnologije DNA

Metoda analize DNA postavila je temelj moderne znanosti i kao takva danas nalazi primjenu u spektru drugih znanstvenih disciplina, pa tako i u kriminalistici za tumačenje bioloških tragova u svrhu identifikacije počinitelja i/ili žrtve kaznenog djela. Brojne su prednosti DNA analize pred klasičnim serološkim metodama. Brza je, učinkovita, daje jednoobrazne, nedvojbene i reproducibilne rezultate. U ovom su članku obrađena dva predmeta teških kaznenih djela u kojima prethodnim vještačenjima bioloških tragova klasičnim serološkim metodama nisu dobiveni rezultati koji bi dovoljno teretili počinitelja u kaznenom postupku pred sudom. Osumnjičenici su zbog nedostatka dokaza pušteni iz pritvora i navedeni su predmeti stajali neriješeni niz godina. Dopunskim vještačenjima metodom analize DNA analizom STR-a utvrđeni su rezultati koji nedvojbeno ukazuju na počinitelja s vjerojatnošću od 1:1 x 1015 te su nakon šest i devet godina od događaja pribavljeni nepobitni dokazi za kazneni postupak pred sudom.

vrednovanje analize DNA ;

DNA analysis method has become a cornerstone of modem science and, as such, is applied extensively in other scientific areas, as well as in the interpretation of biological traces for the purpose of crime perpetrator and/or crime victim identification in crime investigation. The advantages of DNA analysis, in comparison to classical serological methods, are numerous. It is rapid and efficient, and the results obtained are unique, unquestionable and reproducible. Two serious crime cases are presented in the article in which, through previous forensic analysis of biological traces using classical serological methods, no results were obtained proving without reasonable doubt that the perpetrator committed crime. The suspects were set free for the lack of evidence, and cases remained unsolved for years. By using DNA STR technology analysis, in an additional forensic testing, the results unquestionably showed with the probability of 1:1 x 1015 who the perpetrators were so that, six and nine years later, the evidence was obtained making it possible to proceed with the criminal trial.
