I then participate in a scene briefing with attending agency representatives. Determining each agency's responsibility at the scene is essential in my planning of the scope and depth of the scene and the investigation. Once the scene briefing has been established I reconstruct the offense and try to analyze exactly what happened. Since I am the investigating officer the next thing I will do is give a general reconstruction of the event and the scene. I begin by conducting a walk-through of the scene. This will provide me with an overview of the scene and what happened to help aid me in reconstructing the offense. I coordinate all parties involved and those assigned to the scene to their duties to ensure the timely flow of pertinent information for the crime. The focus of the scene appears to be the living room where the body of a 35-year-old parochial school teacher is found. Working outward from our focal point I instruct my other two assisting officers to identify the paths of entry and exit that the suspect took. The first assisting officer reports to me that the window above the kitchen sink is broken and pieces of glass are also discovered in the sink. The second reporting officer reports the sliding glass door in the living room are also broken and there appears to be glass in the living room and on the deck. After we identified all exits and entries I instructed my crime scene technician to set up physical barriers for the scene. She used crime scene tape to block off the scene and other physical barriers such as the doors and walls etc. I have also gathered the crime scene entry log to keep track of those individuals entering and leaving the scene. While reconstructing what has happened my assistants and I have concluded the following, the incident appears to be a robbery that turned into and unintended homicide. The victim found in the living room was partially clothed.
