What is a significant characteristic of circumstantial evidence?

Circumstantial evidence is characterized by its ability to suggest a conclusion through inference rather than providing direct proof of a fact. This type of evidence relies on the context or surrounding circumstances to lead to a logical conclusion about what occurred. For example, if a person is seen near a crime scene carrying a wet umbrella during a storm, one might infer that they were likely at that location when the crime occurred. This inference-making aspect underscores the significance of circumstantial evidence in legal contexts, where it can lead to credible conclusions even without direct evidence.

The other options do not accurately represent the nature of circumstantial evidence. It does not necessarily require a witness, nor is it inherently stronger than direct evidence, which is typically given more weight in legal proceedings. Additionally, while corroborating documents can be beneficial in establishing a case, they are not a requirement for circumstantial evidence itself.
