Abstract: The scientific study and exploration of slough skin cells as physical evidence found at rape crime scene have helped in solving rape cases resulting in the identification, linkage and apprehension of perpetrators. Therefore, investigation of rape is heavily reliant on the collecting, handling and preservation of physical evidence, which often provides the court with conclusive proof of solving this crime. For rape cases, the body of the victims and perpetrators and locations where rape occurs can present physical evidence. This study explored slough skin cells in rape cases as a source of Deoxyribonucleic Acid evidence to identify and link suspects to rape cases. The aim of this study was “to explore slough skin cells as physical evidence in the investigation of rape in Gauteng Province". This qualitative study employed the phenomenological research design. Twenty (20) forensic investigator participants attached to the South African Police Service Local Criminal Record Centre (SAPS LCRC) from Krugersdorp were chosen through purposive sampling as they oversaw conducting forensic investigations at rape crime scenes. Semi-structured one-on-one interviews were adopted as the data collection method. Data collected was analysed using thematic analysis. This study revealed that Krugersdorp SAPS LCRC forensic investigators adhere to and comply with the SAPS guidelines while investigating rape cases in GP. The focus was on the experiences of SAPS LCRC Krugersdorp forensic investigators as it is their responsibility to forensically investigate rape crime scenes in terms of the SAPS LCRC Crime Scene Policy (2005) and SAPS National Instruction (NI) 1 of 2015 on Crime Scene Management. This study highlighted the importance of complying and adhering to the set guidelines when investigating rape cases for slough skin cells as physical evidence. This study, therefore, recommends that non-compliance with the SAPS guidelines of NI 1 of 2015 on Crime Scene Management must be dealt with according to the SAPS Disciplinary Regulations 1 of 2016. Furthermore, it is recommended that the SAPS LCRC CSI policies be reviewed and updated quarterly to keep up with new technology. In addition, it is recommended that the SAPS review and upgrade SAPS LCRC training course materials and manuals and incorporate slough skin cells as physical evidence.
