Which investigative technique is commonly used to resolve arson cases?

• A. Use of aerial surveillance
• B. Using scent detection dogs to identify accelerants
• C. Interviewing all neighbors extensively
• D. Analyzing fire hydrant water pressure

Answer: (B)

Using scent detection dogs to identify accelerants is a highly effective investigative technique in arson cases. These specially trained dogs can detect specific substances, such as gasoline or other flammable liquids, that may have been used to ignite a fire. Their acute sense of smell allows them to find traces of accelerants that may not be visible to human investigators. This is critical in establishing whether a fire was intentionally set, as the presence of accelerants can strongly indicate arson. Dogs can cover large areas quickly and provide investigators with leads on potential entry and exit points for the perpetrator. The use of scent detection dogs adds a valuable layer of capability to the investigative team, helping to substantiate or rule out the possibility of arson based on the physical evidence they uncover. In contrast, aerial surveillance may provide a broader view of a fire scene but lacks the specificity needed to detect accelerants. Extensive interviews with neighbors could yield helpful information but may not directly point to the cause of the fire. Analyzing fire hydrant water pressure is relevant for understanding fire response but does not contribute to identifying the nature or cause of the fire itself. Thus, the use of scent detection dogs stands out as a targeted and effective method for investigating arson.
