Which of the following are indicators of an intentionally set fire?

• A. Evidence of accelerants, multiple points of origin, or witness statements.
• B. A single origin and slow burn
• C. Absence of accelerants
• D. Fire confined to one room with clear entry points

Answer: (A)

Identifying signs of deliberate ignition relies on looking for clear evidence that someone planned and started the fire. The trio listed—accelerants, multiple ignition points, and witness statements—forms a strong, cohesive picture of arson.

Accelerants are flammable liquids used to speed up burning. If investigators detect residues or chemical indicators of a fuel, it strongly suggests someone used an accelerant to start or intensify the fire, rather than it starting on its own.

Multiple ignition points show the fire began in more than one place. A single origin is common in accidental fires, but several distinct origins indicate deliberate placement of ignition sources at different spots, which is a hallmark of intentional ignition.

Witness statements can corroborate suspicious behavior or actions related to starting the fire. If someone reports seeing accelerants brought to the scene, someone lighting multiple spots, or other deliberate actions, this supports the physical evidence.

The other scenarios describe patterns more typical of accidental or natural fires and do not, on their own, indicate intentional ignition. A single origin with a slow burn, absence of accelerants, or a fire confined to one room with obvious entry points could all occur without arson and thus are not as strong indicators.
