Arson investigators are specialized professionals who examine the causes and origins of fires, particularly those suspected to be intentionally set. They work closely with law enforcement and fire departments to gather evidence, interview witnesses, and analyze fire patterns. Their goal is to determine whether a fire was accidental or deliberate, which can lead to criminal charges if arson is suspected. These investigators use various techniques and tools, including forensic analysis and fire scene reconstruction, to uncover the truth behind a fire incident. They often testify in court as expert witnesses, providing crucial information about the fire's cause and the potential motives of suspects involved in the case.
