Which type of evidence includes statements from witnesses related to the case?

Testimonial evidence is defined as statements made by witnesses who recount what they have seen, heard, or experienced in relation to the case at hand. This type of evidence is crucial in legal proceedings because it often provides direct insight into the facts of the case based on eyewitness accounts or expert testimony. The credibility of testimonial evidence can significantly impact the case's outcome, as it often helps establish the circumstances surrounding an incident and may support or refute other types of evidence presented.

In contrast, circumstantial evidence relies on inference rather than direct observation, while direct evidence directly addresses the issue in question without needing further inference. Lastly, documentary evidence includes written materials, recordings, or other documents that support or contradict a case but do not consist of oral statements from witnesses. Thus, testimonial evidence is the correct type of evidence that encompasses witness statements related to the case.
