This paper explains crime scene reconstruction and recommends that the scientific method become the standard methodology for this process.
Abstract
Investigators conduct informal crime scene reconstruction while processing, documenting, and collecting evidence. This process is often subconscious. The formal, second phase of crime scene reconstruction is a conscious process. It takes place after the processing of the scene, analysis of the evidence, and completion of all investigative processes. The methodology for crime scene reconstruction needs standardization for it to mature. The scientific method is a proven systemic process of problem-solving that follows six steps. These steps are to state the problem, develop a hypothesis regarding the explanation or solution of the problem, test the hypothesis by experimentation, form a theory, use theories to predict events, and consider as a scientific law a theory that holds up under testing as an accurate predictor. The hypothesis in crime scene reconstruction needs to be narrow in scope and precise. The investigator must give equal emphasis to all feasible and reasonable possibilities when considering answers to questions. Opinions must rest on an analysis of the physical evidence and known facts. Results must be reviewable, testable, and repeatable. In addition, opinions are always open to new knowledge. The use of the scientific method can overcome obstacles to the admission of testimony. The analysis concludes that a decision template is an appropriate format for applying the scientific method to reconstruction in that it guides the process and documents the analysis.
