The essence of successful criminal investigation hinges on a fundamental principle: it’s not merely about what you know, but what you can substantiate in court. For investigators, this underscores the vital importance of meticulously documenting every facet of the crime scene and their findings. The initial evaluation of the scene includes determining the specific documentation needed to build a solid, court-ready case. As the adage in criminal investigations goes, “If it ain’t on paper, it didn’t happen.”
Crime scene processing transcends the simple collection of photographs and evidence. A skilled investigator or crime scene technician delves deep into the scene’s narrative, unraveling the events’ chronology and verifying if the physical evidence aligns with the accounts provided by victims and witnesses. Moreover, the investigator’s keen eye for detail is crucial in identifying any element that might link the suspect to the crime scene, demanding an exceptional level of awareness and meticulous attention to detail.
Documentation Procedural Summary
The documentation process is a comprehensive task that involves several key steps:
- Scene Evaluation: Begin by reviewing the scene to identify the types of documentation that will be necessary, considering the unique aspects of each case.
- Coordinating Documentation Efforts: Utilize a combination of photographs, videos, sketches, measurements, and detailed notes to capture the scene comprehensively.
- Photographic Coverage: Implement a strategy for photographing the scene that includes overall, medium, and close-up shots. Evidence should be photographed both with and without scales or identifiers for clear reference. Additionally, consider capturing images of victims, suspects, witnesses, and the surrounding area from multiple perspectives, including aerial views or angles mirroring a witness’s viewpoint.
- Video Recording: Supplement photographic evidence with video recordings to provide a dynamic view of the scene and evidence layout.
- Preliminary Sketches: Create initial sketches of the scene, incorporating measurements and noting the positions of key evidence items. These sketches should accurately represent the spatial relationships within the scene, including the placement of furniture and other significant objects, and reference points like adjacent buildings.
- Comprehensive Notes: Document critical information such as the scene’s location, times of arrival and departure, and the scene’s condition upon arrival. Notes should also capture transient evidence like odors, sounds, and visual disturbances, as well as any deviations from standard procedures necessitated by the scene’s specifics.
This meticulous approach to documentation ensures that every piece of evidence and every observation is captured and preserved for analysis and presentation in court, reinforcing the credibility and thoroughness of the investigation. We will explore these tasks in greater detail in Section 2.
