Y-chromosome DNA testing is potentially useful in forensic analysis. The male specific amplification can enable examination of a male perpetrator’s profile even in mixtures with high levels of female DNA in sexual assault cases. This case study presents the application of Y-23 STR loci for identification of perpetrator in the rape case of a poor mentally retarded girl. The crime was revealed when her pregnancy became apparent. The victim was unable to identify the accused and also could not recollect the incident. Throughout the investigation, the investigating authorities submitted blood samples of 22 suspected individuals, along with blood samples of the victim and her male baby for DNA analysis. All the submitted samples were analysed using autosomal and Y chromosome STR DNA analysis.
