Analysis / Reconstruction
Analysis and reconstruction is the process of examining the ALL the crime scene documentation (reports, photographs, sketches, etc.) and evidence in an effort to determine a parameter for which an event(s) took place. This parameter will be use in determining the Best Explanation for a given set of events. The greater the detail of the crime scene documentation, the narrower the parameter may be. The analysis / reconstruction may be of a narrow nature that involves answering a single investigative question, to a full blown “tell us what happened” reconstruction. Ultimately the analyst / reconstructionist will provide an opinion based on the “Best Explanation” which is based on the totality of the evidence, documentation and the context of the crime scene. An analysis will rarely provide an opinion that describes every action within a scene. This may be due to limited documentation or a lack of evidence to simply explain what happened during that specific event. The analysis in other areas of the incident may eventually provide useful information that may assist in forming an opinion in some of these areas of limited documentation and in other instances; it will provide no additional helpful information. In these instances, the analyst may just have to indicate they don’t know what happened. Analysis may be provided in the following areas:
Crime Scene Analysis / Reconstruction
This type of analysis may provide an opinion of a general crime scene nature, such as is the movement of the suspect possible based on the incident, did the incident occur in the manner described by the involved individual(s), etc. This may also include an analysis of the complete incident (e.g. tell us what happened), which may include bloodstains and shooting scene evidence. Crime scene analysis may also be used to validate or refute an individual’s statement and/or testimonial evidence.
Bloodstain Pattern Analysis
This aspect of reconstruction is an extensive examination of the bloodstains deposited within the scene or in some instances the lack of bloodstains. The analyst must take into consideration the various stain patterns within the scene, which includes the location of the stain patterns and the individual characteristics of the pattern. These characteristics include the orientation, volume, number of stains and the dispersion of the overall stain pattern as well as the size and shape of the stain pattern and individual stains present. The analyst recognizes and examines the physical characteristics of a representative set of individual stains within a pattern in an attempt to associate the pattern with a specific event(s) that occurred within the scene. A proper analysis includes a review of ALL the evidence and documentation in order to establish a proper parameter for which the bloodstains were deposited within the scene.
Shooting Incident Reconstruction
Proper documentation of a shooting incident may allow the reconstructionist to identify the trajectory of a fired bullet (or projectile). This allows for the establishment of the parameter of the bullets path through the scene. Shooting Incident Reconstruction uses mathematical and scientific principles to establish these parameters. Shooting Incident Reconstruction may be used to validate and/or refute an individual’s statement and/or testimonial evidence as to their actual location during the shooting incident.
Crime Scene Mapping
Crime Scene Mapping is a process that may add additional information for the investigator, detective, prosecutor, defense attorney, etc. The crime scene documented thoroughly by photographs provides great insight into the crime scene and the events that took places. Crime Scene Mapping may provide additional information that the photographs simply cannot provide, such as spatial relationships of the evidence and other objects within the scene, bloodstains, shooting incident evidence on walls, etc.
Set up an In-house Investigator Training Program
The International Association for Identification accepts various training to fulfil the training requirements for any of the various Certification Programs they offer. One of the areas the International Association for identification recognizes a well-structured in-house training program. Most agencies have some required training process prior to allowing the newly hired investigator to function in a solo capacity. Everett Baxter Jr Forensics, LLC can assist in developing a formalized training program, which includes training documentation and evaluation forms and booklets. This process will allow the investigator to utilize some of the training hours when applying for the various certification tests.
Initial In-house Training:
Upon approval by the Crime Scene Certification Board, an agency’s structured training program hours may be reciprocated for portions of or for the amount of required hours of instruction for the appropriate crime scene certification.
One might ask, since they have a Forensic Science degree from an accredited college/university, will some of these hours count towards certification. According to the International Association for Identification:
Online courses and college and university curriculum courses are not accepted for certification/recertification purposes.
Therefore, those education hours do not count for certification purposes.
