What type of evidence is described as tangible and can be observed by the senses?

The type of evidence that is tangible and can be observed by the senses is demonstrative evidence. This form of evidence is often used in investigations and legal settings to illustrate or clarify a point. It can include physical objects, images, diagrams, or models that help convey information in a way that is easily understood by those involved in a case.

Demonstrative evidence serves as a visual aid that allows investigators and jurors to better grasp complex concepts or details relevant to a fire investigation. For instance, photographs of the fire scene, burn patterns, or charred materials can serve as demonstrative evidence, helping to recreate the circumstances of the event under examination.

The other types of evidence differ in nature: documentary evidence refers to written materials such as reports or records; circumstantial evidence relies on the inference of facts to draw conclusions; while testimonial evidence consists of statements or declarations made by witnesses. Each type has its own role in investigations, but demonstrative evidence stands out for its immediacy and physical presence, which can be directly observed and analyzed.
