Which type of evidence includes physical items collected from a crime scene?

The correct answer is physical evidence because this type of evidence encompasses tangible items that are collected from a crime scene. Physical evidence can include items such as fingerprints, weapons, blood samples, clothing, or any other objects that can provide direct links to the crime. This type of evidence is crucial as it can help to establish a connection between the suspect, the victim, and the crime itself through scientific analysis, such as DNA testing or ballistics.

In contrast, testimonial evidence refers to statements made by witnesses or victims about what they saw or heard, which relies on human recollection and perception. Documentary evidence involves records or documents that can provide information about the case, such as contracts, photographs, or digital records. Demonstrative evidence serves to illustrate or clarify testimony but does not come from the crime scene itself; rather, it is meant to help the jury understand evidence better, such as maps, diagrams, or models. Thus, physical evidence is uniquely characterized by its direct connection to the crime scene and its role in criminal investigations.
