What is the first main focus of an arson investigation?

The search of the fire scene must focus on finding the fire’s origin, which may be most productive in any search for an accelerant or ignition device. How the fire started gives the best indication as to whether the fire was accidental or intended.

How does a fire investigator search for a pattern in a fire scene?

Observation of fire patterns begins on the outside of the building, where the investigator conducts a 360° survey of the building, taking note of areas where external fire and smoke patterns are observed. This will help the investigator determine where to look inside.
