Which of the following is NOT a type of evidence?

Factual evidence is not typically classified as a distinct type of evidence in criminal investigations. Instead, evidence is usually categorized into types such as circumstantial, testimonial, and physical.

Circumstantial evidence refers to indirect evidence that implies a fact or event without directly proving it, allowing for inference. Testimonial evidence is derived from witnesses who provide oral or written statements regarding what they observed or know. Physical evidence includes tangible items that can be collected and analyzed, such as fingerprints, weapons, or DNA. Each of these types plays a crucial role in building a case.

In contrast, while "factual" can describe information that is based on facts or reality, it does not represent a specific category of evidence within the framework of criminal investigation. Understanding the distinct types of evidence is critical for investigators to gather, analyze, and present a compelling case.
