What are the three types of evidence commonly found at a crime scene?

The correct answer emphasizes the three predominant categories of evidence that crime scene investigators typically collect and analyze: physical, biological, and digital evidence.

Physical evidence refers to tangible items that can be observed and collected at a crime scene, such as weapons, fingerprints, or fibers. These items can provide crucial links between a suspect, victim, and the crime scene.

Biological evidence includes any biological material that can be linked to a person or an organism, such as blood, saliva, hair, or other bodily fluids. Analyzing biological evidence can yield DNA profiles that are instrumental in identifying individuals involved in a crime.

Digital evidence encompasses information stored or transmitted in digital form, which can include data from computers, smartphones, and other electronic devices. In today's world, digital evidence is increasingly vital in investigations, as it can reveal communication patterns, locations, and crimes committed in the digital realm.

Understanding these three types of evidence allows investigators to gather a comprehensive view of the crime, offering a blend of physical, genetic, and electronic data that can be crucial for solving criminal cases.
