In forensic science, what does the term 'individual characteristic evidence' refer to?

The term 'individual characteristic evidence' refers to evidence that can be traced to a unique source. This type of evidence is critical in forensic science, as it allows investigators to link physical evidence found at a crime scene directly to a specific individual or object. For example, fingerprints, DNA profiles, and specific tool marks are all types of individual characteristic evidence because they possess unique features that can be definitively matched to a person or a particular item.

This distinctiveness is essential in forensic investigations as it strengthens the connection between suspects and criminal activity. The uniqueness of this evidence makes it invaluable in legal proceedings, often serving as key pieces of information in establishing proof of guilt or innocence. Other types of evidence may offer insights or assist in narrowing down possibilities, but individual characteristic evidence provides a definitive link that can directly identify an individual.
