Which example best defines physical evidence?

Physical evidence refers to tangible items that can be collected and analyzed to support investigation and prosecution efforts. A scrap of clothing found at a crime scene is a concrete example of physical evidence because it can be physically collected, preserved, and analyzed for various forensic purposes. This could involve examining the fabric for DNA, fibers, or other trace evidence, which can directly link an individual to the crime or the crime scene.

In contrast, a spoken statement from a witness is considered testimonial evidence and is not a physical item that can be examined or analyzed in a laboratory. Similarly, a sketch of the crime scene is representational and is a form of demonstrative evidence but not physical evidence in itself. A police report summarizes information about a crime but does not comprise actual items involved in the investigation.
