Abstract
This research was aimed at exploring the importance of bloodstain pattern analysis as another mechanism or a technique used during a murder investigation. The emphasis in this research was more on the blood found at the crime scene as it may lead to solving the crime. Research shows that resolving of crime begins at the scene and how evidence found at these scenes are analysed, maintaining the chain of possession.
The researcher adopted a qualitative approach, with the assistance of participants who are knowledgeable and experts in this regard. Furthermore, literature study on the subject matter was used in order to ensure comprehensive research with the aim of capacitating investigators of serious crime in South Africa. In order to do this, two critical questions were used as a benchmark, namely: “What are the objectives of murder investigations?” and “What is the significance of bloodstain pattern found in the murder crime scene?” The qualitative approach was used to collect data from the participants who constantly investigate the crime scene where blood is found, including case study and literature review. The researcher wanted to bring to the attention of the crime scene investigators that blood found at the crime scene carries more valuable evidence that is acceptable in court. The bloodstain found at the scene gives the entire movement and direction of both victim and perpetrator.
The researcher recommends that the crime scene analysts and examiners be trained on the bloodstain pattern analysis as a technique in investigation. The researcher discovered that many members are not trained on the BPA; and also recommends that refresher courses be offered to those who have completed the course.
