Which type of evidence is characterized by its ability to identify a unique source?

Individual Characteristic Evidence is defined by its uniqueness and specificity to a single source. This evidence can be tied directly to a particular individual or object, distinguishing it from other types of evidence. Examples include fingerprints, DNA profiles, and striations on bullets.

These characteristics make Individual Characteristic Evidence particularly valuable in forensic investigations, as it can definitively link a suspect to a crime scene or victim, providing clear and compelling proof of involvement. In contrast, other types of evidence, such as Class Characteristic Evidence, may only be able to associate evidence with a group but not pinpoint an exact source. Circumstantial Evidence is indirect and relies on inference rather than direct proof, while Testimonial Evidence is based on witness accounts rather than physical attributes. Therefore, the defining trait of Individual Characteristic Evidence is its capacity to identify and connect to a distinct source, making it a crucial component in forensic analysis and legal proceedings.
