What is circumstantial evidence primarily used for?

Circumstantial evidence is primarily used to support an inference rather than directly prove a fact. This type of evidence relies on the relationship between facts and allows for the deduction of conclusions based on the information presented. For example, if someone is seen running away from a crime scene with a weapon in hand, this circumstantial evidence may lead to the inference that they were involved in the crime, although it does not directly prove that they committed it.

The strength of circumstantial evidence lies in its ability to build a narrative or context around a situation, suggesting likelihoods based on the observed facts. It's important to note that while it does not provide direct evidence, when combined with other evidence, circumstantial evidence can significantly strengthen a case. By relying on the inference drawn from gathered facts, circumstantial evidence plays a critical role in investigations and legal proceedings where direct evidence may not be available.
