Why are elimination prints important?

• A. They indicate the time of a print
• B. They help identify suspects
• C. They exclude prints that do not belong to authorized persons
• D. They determine the age of a print

Answer: (C)

Elimination prints are used to remove prints from people who were present or cleared so they aren’t mistaken for prints from the crime scene. By collecting and using these known-good prints, investigators can rule out innocents early, which prevents a false match from directing the investigation toward someone who wasn’t involved. This improves accuracy by narrowing the pool of potential matches to those who could realistically be the suspect. They don’t tell when a print was made or how old it is, and they aren’t used to identify suspects by themselves; their main purpose is to exclude prints that don’t belong to authorized persons.
