What type of evidence is based on facts that are not directly observed?

Circumstantial evidence is based on facts that are not directly observed but can imply or suggest a conclusion or fact based on the circumstances surrounding a case. This type of evidence requires an inference to connect the dots, meaning that while the evidence itself does not prove something outright, it can help build a narrative or support a theory when considered alongside other evidence.

For example, if a suspect's fingerprints are found at the scene of a crime, that is direct evidence. In contrast, if a neighbor's testimony indicates they saw the suspect leaving the area shortly after a crime occurred, that is circumstantial evidence; it suggests the suspect's involvement without directly witnessing the crime itself.

Understanding circumstantial evidence is crucial in criminal investigations, as it often plays a significant role in establishing a timeline or motive, contributing to the overall picture of the case even when no one directly observed the crime being committed.
