A perfect crime is a crime that is undetected, unattributed to an identifiable perpetrator, or otherwise unsolved or unsolvable.

1160-498: The death is never identified as murder is an example of one of the more rigorous definitions of perfect crime. Other criminologists narrow the range to only those crimes that are not detected at all. By definition, it can never be known if such perfect crimes exist.
