Documentation in Forensic Fire Investigation

What is Documentation?

  • Within the context of forensic fire investigation, documentation refers to the collection, recording and preserving of all information related to the fire incident.
  • Documentation serves as an official record, aiding investigators in their analysis and potentially serving as legal evidence.

Types of Documentation

  • Documentation may include photographs, videos, sketches, and notes, capturing the state and details of the fire scene exactly as discovered.
  • Detailed reports are another form of documentation - these systematically detail an investigator’s actions, findings, and conclusions.

Importance of Documentation

  • Accurate and thorough documentation is essential to ensure the validity of investigation findings, especially when used as part of legal proceedings.
  • The detail contained in documentation can help observers and readers understand the nature of the fire incident, even if they were not physically present at the fire scene.
  • Documentation allows for retrospective analysis, further investigations or audits.

Process of Documentation in Fire Investigation

  • Investigators start documentation as soon as they arrive at the fire scene, beginning with initial observations and including images of unique identifiers such as addresses or signage.
  • The scene is documented systematically, ensuring coverage of all significant aspects - this can be guided by a checklist including areas to inspect, items to record and specific details to note.
  • Changes to the fire scene during the investigation, e.g., removal or alteration of objects, are also documented.

Photographic Documentation

  • Photographs serve as a reliable record of the fire scene in its original state, providing a visual backup to written reports.
  • Photographs are typically taken from multiple angles and distances, including wide-angle, mid-range, and close-up shots to capture varied levels of detail.
  • It’s important to include a scale in photographs where size or distance is relevant to the investigative analysis.

Note Taking and Sketching

  • Written notes document observations, hypotheses, and initial findings of the investigation.
  • Sketches may be created as a way of visually noting spatial relationships, patterns, or specific items of interest at the fire scene.
  • Both notes and sketches should be clearly dated and signed, ensuring accountability and increasing their credibility as pieces of evidence.

Final Documentation and Report Writing

  • A comprehensive fire investigation report pulls together all collected documentation into an orderly, understandable format.
  • The report details the scene of the fire, evidence collected, laboratory results, an analysis of findings, and the determined origin and cause of fire.
  • The report needs to be factual, objective, and clear to serve as a reliable legal document. Any assumptions or opinions should be clearly stated as such and justified with supporting evidence.

In conclusion, in a forensic fire investigation, documentation is the crucial bridge between the physical fire scene and the subsequent analysis that occurs - it provides the enduring primary evidence for the study of the fire and its cause.
