What type of evidence consists of tangible items that can be seen, touched, smelled, or heard?

Demonstrative evidence encompasses tangible items that provide a physical representation or illustration related to a case. This type of evidence can include objects like tools, debris from the scene, or samples of substances that can be observed through the senses. It serves to help convey information visually or physically, making it easier for investigators, jurors, and other professionals to understand the nature of the evidence in relation to the situation being examined.

On the other hand, documentary evidence refers to documents or records that provide information but are not physical objects. Testimonial evidence consists of statements made by witnesses or experts and relies on verbal communication rather than tangible items. Illustrative evidence, while related, specifically involves aids like diagrams or photographs that illustrate or represent aspects of the case but do not typically consist of physical items that can be directly interacted with. Hence, it is demonstrative evidence that best fits the description of tangible items that can be seen, touched, smelled, or heard.
