A perfect crime is a crime committed with sufficient planning and skill that no evidence is apparent, and the culprit cannot be traced. In the sociological field, crime is the breach of a rule or Law for which some governing authority or force may ultimately prescribe a Punishment Evidence in its broadest sense includes anything that is used to determine or demonstrate the Truth of an assertion The term can also refer to a crime that remains undetected after commission, or sufficiently unsubstantiated to prevent active investigation, so that nobody knows conclusively if the crime has in fact been committed.
In traditional usage the term does not include crimes that merely have not yet been solved. Many crimes go unsolved due to insufficient attention, lack of police resources, or to investigator inexpertise or incompetence in overlooking vital evidence. For example, in the well-known case of Jack the Ripper, plenty of evidence was left at the crime scenes, but the crimes were never solved. Jack the Ripper is an alias given to an unidentified Serial killer active in the largely impoverished Whitechapel area and adjacent districts of London As used by some criminologists, and others who study criminal investigations (including mystery writers), a perfect crime goes unsolved not because of incompetence in the investigation, but because of the cleverness and skill of the criminal. [1] I. e. the defining factor is the primary causative influence of the criminal's ability to avoid investigation and reprisal, and not so much the ability of the investigating authory to perform its duties.
Since evidence must be matched to find the culprit, the best candidate to commit a perfect crime would apparently be completely disassociated from the circle of suspects normally questioned by police (friends, family, business colleagues, etc. ). In practice, however, those who commit serious crimes are usually linked to the victim in some way, and police experience usually allows swift identification of the likeliest suspects. A crime based on a chance meeting, such as a rape, murder or mugging, can go undetected if no connection remains. Rape, also referred to as Sexual assault, is an Assault by a person involving Sexual intercourse with or Sexual penetration of another person Murder is the unlawful killing of another human person with Malice aforethought, as defined in Common Law countries However, a rapist will most likely leave his DNA (e. Deoxyribonucleic acid ( DNA) is a Nucleic acid that contains the genetic instructions used in the development and functioning of all known g. in the form of semen) and sustain minor injuries, which might indicate his guilt; a mugger might be found with his victim's belongings.

Many criminals spend stolen money too freely or brag about their crime.
A murder committed by somebody who had never before met the victim, has no criminal record, steals nothing and tells no one might be a perfect crime. According to criminalists and scientists, perfect crimes do exist. Similarly, criminals are able to keep their identity concealed by performing their crimes in areas of high public traffic, where DNA from a wide variety of people is present, therefore creating the impression of 'finding a needle in a haystack'.
