What are the common signs that indicate arson?

The presence of multiple ignition points combined with the absence of any accidental causes is a significant indicator of arson. In fire investigations, multiple distinct areas of origin can suggest the deliberate setting of the fire, as most accidental fires typically originate from a single source. If investigators observe several ignition points, it raises a red flag that someone may have intentionally ignited the fire in multiple locations, a common tactic used in arson to ensure that the flames spread more widely and quickly.

Additionally, ruling out accidental causes is essential in confirming suspicions of arson. Fire can start for various accidental reasons, such as electrical malfunctions, human error, or natural events. When these factors are systematically excluded, and multiple points of origin are confirmed, it strongly supports the hypothesis that the fire was intentionally set.

In contrast, other choices may provide less relevant or misleading information regarding arson. The presence of fireworks residue could be related to other events unrelated to arson, while natural fire spread indicators typically suggest accidental or environmental causes. Frequent fire occurrences in the same location may raise suspicion, but they do not inherently prove that each fire was set deliberately without further context regarding the causes.
