Perfect crime is a colloquial term used in law and fiction (principally crime fiction) to characterize crimes that are undetected, unattributed to a perpetrator, or else unsolved as a kind of technical achievement on the part of the perpetrator.
In certain contexts, the concept of perfect crime is limited to just undetected crimes; if an event is ever identified as a crime, some investigators say it cannot be called 'perfect'.
A perfect crime should be distinguished from one that has merely not been solved yet or where everyday chance or procedural matters frustrate a conviction. There is an element that the crime is (or appears likely to be) unable to be solved.
