Investigate Crimes using Good Decisions to Prove Cases

Crime Scene Decisions is built around the idea that Decisions Solve Cases because every crime is different, and yet they are all similar. So, an investigator should approach a case with a decision method designed to obtain the evidence to prove who did what through evidence of presence and action. The philosophy is to start with scenes, end with evidence to will prove who did what. Actionable details, or decisions make the book different. The common tendency is to view crime as historical, and work backward, assuming an inevitability of history. Crime Scene Decisions proposes crimes as a series dynamic of interactions, with scenes leaving traces on each other. Crime Scene Decisions is designed for the initial responder who arrives to the case and has the opportunity to set the investigation on the right course. The scenes are as fresh as they will be, and grow stale by the minute. Crime Scene Decisions is organized around the most basic element in any case; the scene type. The scenes exist before the crime. When investigators investigate cases, they are really investigating scenes. Scenes are the start of everything. Every crime has multiple scenes, as they are any entity within the case. Places, things, and people are scenes because they all have the capacity to produce and carry evidence. This definition extends to cyberspace as crimes take place there, and evidence is part of the case.

Advantages and Benefits

Centering the investigation on the scene first and looking at evidence second provides a lot of potential advantages and benefits to the investigator. Fundamentals of Crimes. Learn how crimes happen, and how scenes come together to create evidence. Efficient use of resources. Save time by using a direct route. Even if the route is longer, and shortcuts seem desirable, the reality is a thorough investigation is the fastest route to getting it done. Unbiased work. Scene-based, evidence-centered investigations emphasize what is important; the facts. Thorough investigations also allow for a neutral evaluation of the evidence to build a case. They prevent bias, and reduce the danger of the innocent being convicted, and the guilty from skating. Expandability. By keeping the same methods, an investigator can expand an investigation and assign tasks based on scene or evidence. Completeness. Thorough investigations provide answers get less court time, and the investigators do not have to conduct time-consuming follow-up that should have been done in the first place. Examples. Crime Scene Decisions provides 23 example scenarios to show how the methods work within the cases. A disciplined approach to solving cases makes the work easier.

The Method

Crime Scene Decisions is based on the two parts of every crime; scenes, and evidence. The method has four questions that break down any crime. 1. Designate the scene. Why is this a scene? Every entity involved in a case is a scene, but knowing why it is a scene helps start the process. 2. Analyze the scene.
 How does the scene work? The mechanics of a scene are how it functions in the case. 3. Evaluate the evidence potential. How would the evidence work in this scene? Every scene has evidence potential based on the evidence characteristics. 4. Work the evidence. How to obtain the evidence from this scene? This final step is using fundamental evidence skills to obtain the evidence to prove who did what. These four steps further break down to subsets within each step. This is not a checklist, but a set of considerations for an investigator looking at a crime, and trying to come up with a provable answer to who did what.
