What characterizes individual evidence in criminal investigations?

Individual evidence is characterized by its unique association with a specific source or individual. This type of evidence can establish a direct link between the evidence and a particular suspect, making it extremely valuable in criminal investigations. For example, fingerprints, DNA, or specific tool marks can identify one person or item out of many. The uniqueness of this type of evidence helps investigators answer crucial questions about the crime and the perpetrator's identity, aiding in establishing guilt or innocence beyond reasonable doubt.

In contrast, options that refer to common origins, general applicability, or repetitive patterns do not hold the same level of specificity associated with individual evidence. Individual evidence is defined by its ability to distinctly connect back to an individual source, which is why the emphasis on a unique association is key in differentiating it from other types of evidence that may show broader or less specific links.
