Which type of evidence is typically used to link a suspect to a crime scene through physical transfer?

• A. Trace evidence
• B. Character evidence
• C. Hearsay
• D. Opinion evidence

Answer: (A)

Trace evidence involves physical materials that are transferred between a person and objects or scenes during contact. This type of evidence is what investigators look for when trying to connect a suspect to a crime scene because the material left behind can originate from the suspect or from the scene itself and be analyzed to show a common source. Examples include fibers from clothing, hairs, soil, glass fragments, pollen, or gunshot residue. By collecting trace evidence from the suspect and the scene and analyzing it with appropriate methods, investigators can establish a link based on the transfer of material.

Character evidence, on the other hand, relates to a person’s character or propensity and is not physical material left at a scene. Hearsay consists of out-of-court statements offered for truth, not physical transfer. Opinion evidence is testimony about conclusions or inferences drawn by a witness, rather than tangible materials that tie someone to a location.
