Study Notes
Investigation of Arson Scene
Investigating an arson scene involves securing the scene, documenting evidence, interviewing witnesses, analyzing fire patterns, and determining the cause of the fire. Each step is crucial to ensuring a thorough and accurate investigation.
Securing the Scene
The first step in investigating an arson scene is to secure the scene. This involves identifying and controlling access to the scene to prevent contamination of evidence. Investigators should document the scene, take photographs, and create a sketch or diagram of the scene. They should also protect the scene from weather conditions, such as rain or wind, which can alter the scene or extinguish evidence.
Documenting Evidence
Documenting evidence is a critical aspect of the investigation. Investigators should collect physical evidence from the scene, such as accelerants, tampered utilities, and specific burn patterns, which may indicate criminal activity. They should also document the condition of doors, windows, and other openings, as well as the position of timers, switches, valves, and control units for utilities, detection systems, and suppression systems.
Interviewing Witnesses
Interviewing witnesses is an essential part of the investigation. Investigators should identify the identities of witnesses and conduct interviews. They should document the statements of first responders, the person who reported the fire, and any other witnesses. They should also ask about the condition of the building or vehicle before the fire and identify any suspicious activities.
Analyzing Fire Patterns
Analyzing fire patterns involves examining the physical evidence to determine the cause and origin of the fire. Investigators should consider the location and distribution of fire damage, as well as the presence of accelerants. They should also look for evidence of arson, such as burn marks, melted material, and charred objects. The use of technology, such as 3D laser scanners and field portable Gas Chromatography/Mass Spectrometry (GC/MS) systems, can aid in the analysis of fire patterns.
Determining the Cause
Determining the cause of the fire involves developing a hypothesis based on the evidence and testing that hypothesis. Investigators should consider the fire's origin, the first fuel ignited, and the circumstances of the event that brought the two together. They should also consider alternative hypotheses, such as electrical malfunctions or natural causes, and eliminate them based on the evidence.
In conclusion, the investigation of an arson scene involves a systematic and scientific approach to securing the scene, documenting evidence, interviewing witnesses, analyzing fire patterns, and determining the cause of the fire. This process ensures that all aspects of the scene are thoroughly examined and that any criminal activity can be identified and addressed.
