A perfect crime is a crime committed so perfectly that no evidence is apparent, and the culprit cannot be traced.
Since evidence must be matched to find the culprit, the best way to commit a perfect crime appears to be one outside the circle of suspects that police can question. In practice, however, those who commit serious crimes are usually linked to the victim in some way, and the police know from experience which people to question. A crime based on a chance meeting, such as a rape, murder or mugging, can go undetected if no connection remains.
