Circumstantial evidence is evidence that implies something is true and can be used to infer a conclusion, but does not directly prove the conclusion is true. It is also known as indirect evidence. Examples of circumstantial evidence include observations, records, and statements that lead to an inference. Circumstantial evidence is often used in court cases to prove facts and establish guilt or innocence. There are three types of circumstantial evidence: real, demonstrative, and documentary. Real evidence is physical evidence such as a weapon, clothing, or fingerprints. Demonstrative evidence includes the use of diagrams, charts, photographs, and videos to demonstrate events or facts. Documentary evidence includes documents such as contracts, letters, emails, and financial records.
