Which of the following is an example of demonstrative evidence in an investigation?

Demonstrative evidence is designed to illustrate or clarify information for the court, often making it easier for the jury to understand complex information. In this context, maps and diagrams serve as valuable tools in an investigation as they can visually depict the scene of the incident, the layout of a property, or the paths taken during an event. These visual aids help to convey factual information that supports the case, offering a representation that can supplement oral testimony and other forms of evidence.

By providing a visual reference, maps and diagrams can enhance understanding of spatial relationships and the sequence of events, making it a critical form of demonstrative evidence in investigative processes. Witness testimonies, expert analyses, and confidential reports, while important, do not fall under the category of demonstrative evidence, as they do not serve primarily to illustrate or clarify physical facts directly related to the investigation.
