Arson investigation is the process of determining the cause and origin of a fire that is suspected to be intentionally set. Investigators examine the fire scene for evidence, such as burn patterns, accelerants, and potential ignition sources. They also interview witnesses and gather information about the property and its occupants to identify any motives for committing arson. The role of an arson investigator is crucial in these cases, as they work closely with fire departments, law enforcement, and sometimes insurance companies. Their findings can lead to criminal charges against individuals responsible for the fire, helping to prevent future incidents and ensure public safety.
