Investigation of a Crime Scene: Applying Biological and Chemical Forensic Techniques

Investigation of a Crime Scene: Applying Biological and Chemical Forensic Techniques

The purpose of this experiment was to explore the principles of investigating a crime scene; utilizing both biological and chemical laboratory techniques. Collecting proper evidence is crucial to crime scene investigation. The insight that an investigator may gain about a perpetrator can be determined by analyzing the physical evidence obtained at the scene, and therefore an investigator must carefully examine numerous pieces of evidence found at a crime scene. However, the knowledge and education of the investigator are able to elucidate both the obvious and the obscure. Each piece of evidence may provide a clue to who committed the crime that is under investigation. Techniques such as hair, gunshot, fingerprint, footprint and blood spatter analyses were learnt and then used in the investigation process. This research project involved the investigation of a hypothetical crime scene, which was analyzed by using the aforementioned forensic techniques.
