Final answer:
To determine if a fire may be incendiary in nature, investigators look for possible motive, multiple points of origin, use of accelerants, unusual burn patterns, and presence of ignition devices.
Step-by-step explanation:
To determine if a fire may be incendiary in nature, investigators look for specific indicators:
- Possible motive: Investigators consider if there's a motive for intentionally starting the fire, such as insurance fraud or revenge.
- Multiple points of origin: If a fire starts in different areas simultaneously, it suggests arson.
- Use of accelerants: Indicators like strong odors, strange burn patterns, or residue can point to the use of accelerants.
- Unusual burn patterns: Investigators examine if the fire exhibits patterns inconsistent with accidental origins.
- Presence of ignition devices: The discovery of matches, lighters, or other ignition devices at the fire scene can be incriminating evidence.
These indicators help investigators differentiate between a naturally occurring fire and one that is suspected to be intentionally set.
