Abstract
Semen is the most significant evidence that can help to investigate a rape crime. All types of rape crimes (sexual assault, sodomy, rape and murder) includes many types of evidence items such as victim and suspect clothing, bedding at crime scene, on floor and walls, on body of victim and suspect and sometime on different objects like condoms and copper-T. From all these, clothing and bedding are most important as analyst can get complete single source DNA profile of assailant by identifying individual stains. Unfortunately, in a country like Pakistan, where there is no sense to deal with evidence items due to low literacy rate, the chances of recovering sperms from clothing is nearly zero.
In this study, a comparison of sperm retention after washing among different fabrics was done. For this purpose, commercially available detergents and commonly used female and male fabrics were tested and compared results for sperm retention after washing with detergents and distilled water with different washing periods. This study was designed to assess the effect of washing with different time intervals using five detergents available in the market on various fabrics stained with seminal material. Fabrics used in this study were cotton, wool, polyester and mixture of all these with different proportions. Different results were obtained from different detergents used on different fabrics to remove semen stains. Data obtained was analyzed in different aspects with one variable in each aspect.
