Which of the following best defines "physical evidence"?

The definition of "physical evidence" is best captured by the idea of tangible objects that can be collected at a crime scene. Physical evidence plays a critical role in crime scene investigations because it comprises any physical items that can provide direct or circumstantial evidence related to a crime. This can include fingerprints, DNA, clothing, weapons, and other materials that can be analyzed and presented in court. By being tangible, these objects can be observed, documented, and matched to individuals, places, or events involved in a crime, making them invaluable for establishing facts about the case.

In contrast, circumstantial information related to a case is more abstract and does not constitute physical evidence. Testimonial accounts are based on individuals' observations and memories, indicating the need for corroboration with physical evidence. Digital data may also contribute to an investigation but falls under a different category than physical evidence, as it usually exists in a virtual format rather than as physical items. Thus, the emphasis on tangible items clearly distinguishes physical evidence as a concrete and essential aspect of crime scene management.
