Abstract
DNA typing of forensic evidence necessary to prosecute rape cases is a routine analysis in criminal forensic casework. Prenatal samples can be used as DNA evidence for such cases by establishing their paternal origin. Herein we report two cases of sexual abuse. The first case regards a thirteen years old girl's rape that resulted in pregnancy. The girl reported the assault after four months and the only available evidence for DNA typing, at that time, was the amniotic fluid. The second case regards a sixteen years old girl's rape by her alleged father. The rape resulted in pregnancy that was terminated three to four weeks after conception. In order to extract DNA from the amniotic fluid sample, the laboratory's protocol established for DNA isolation from tissues was slightly modified. In this presentation we report the modified protocol. In addition we present our approach to process the “abortion specimen” as DNA evidence and the results of DNA analysis.
