Which type of evidence will unequivocally link a crime scene to a suspect?

Linking evidence is the best type of evidence that connects a crime scene to a suspect. This kind of evidence typically includes physical items or biological samples that can directly associate an individual with a specific place, act, or moment in time where a crime has occurred. Examples include fingerprints, DNA, or specific fibers that can be traced back to the suspect, creating a strong connection between them and the crime scene.

In contrast, motive evidence pertains to a suspect's reason for committing a crime but does not physically link them to the scene or the act itself. Class evidence, while useful in narrowing down potential suspects by placing them within a larger group, lacks the specificity needed to connect an individual definitively. Circumstantial evidence suggests a possibility or likelihood of involvement based on the context around the crime but does not provide direct proof. Thus, linking evidence stands out as the most compelling form of evidence in solidifying an individual's connection to a crime scene.
