Question

fingerprints discovered on the knife found on the driveway

could belong to the victim and/or the attacker, but are probably an example of locards exchange principle

would not exist because the knife has been wiped with a cloth

certainly belong to the victim laying in the driveway

certainly belong to person committing the crime

Explanation:

Locard's Exchange Principle states that when two objects come into contact, a transfer of materials occurs. Fingerprints on the knife could be from the victim and/or attacker due to this principle. Just because a knife is wiped doesn't mean fingerprints won't exist if not done thoroughly. We can't be certain they belong only to the victim or only to the criminal.

Answer:

could belong to the victim and/or the attacker, but are probably an example of Locard's Exchange Principle
