Which type of evidence is typically described as that which can be touched or collected?

Physical evidence refers to tangible items that can be collected and examined in a crime investigation. This type of evidence includes objects like fingerprints, weapons, clothing, and biological samples such as blood or hair. Because physical evidence can be touched, collected, and analyzed in a lab, it plays a critical role in establishing facts and supporting or refuting hypotheses in a case.

On the other hand, circumstantial evidence suggests a connection between an event and a person but does not directly prove it. Testimonial evidence involves statements made by witnesses or experts regarding what they saw or experienced, and demonstrative evidence is used to illustrate or explain other evidence but does not itself have a direct link to the crime scene or occurrence. Therefore, the definition of physical evidence focuses precisely on its tangible and collectable nature, distinguishing it as the correct choice.
