Who should conduct the interview of potential witnesses to a fire?

• A. Fire investigator
• B. Incident commander
• C. Police detective
• D. Insurance investigator

Answer: (A)

Interviewing potential witnesses is a critical step in fire investigations because accurate, nonleading accounts help establish how the fire started and what happened at different times. The fire investigator is the best fit to conduct these interviews since they are trained to ask focused questions about ignition sources, materials involved, and the sequence of events, and to document statements in a way that can be cross-checked against physical evidence at the scene. This information is then integrated with burn patterns and scene findings to determine the origin and cause. The incident commander focuses on safety and scene control, not on collecting specialized testimony for origin-and-cause analysis. Police detectives may handle criminal aspects in some cases, and insurance investigators may gather information for claims, but the specialized determination of how a fire started rests with the fire investigator.
