Answer: Because the suspect may have a reason for his or her fiber being there.
Explanation: if they are a roommate, friend, or someone who had access to the crime scene, the evidence of a matching fiber could easily be explained away. It is best to question a suspect about if they had been to that location before. If they say no, they are locked into that answer, thus there is no innocent excuse for the fiber being present.
