A cold case is a
crime
In ordinary language, a crime is an unlawful act punishable by a state or other authority. The term ''crime'' does not, in modern criminal law, have any simple and universally accepted definition,Farmer, Lindsay: "Crime, definitions of", in Ca ...

New technological methods developed after the crime was committed can be used on the surviving evidence to analyse causes, often with conclusive results.
Characteristics
Violent or major crime
Typically, cold cases are
violent and other major

A felony is traditionally considered a crime of high seriousness, whereas a misdemeanor is regarded as less serious. The term "felony" originated from English common law (from the French medieval word "félonie") to describe an offense that res ...

.
Sometimes disappearances can also be considered cold cases if the victim has not been seen or heard from for some time, such as the case of
Natalee Holloway or the
Beaumont children.
About 35% of those cases are not cold cases at all. Some cases become instantly cold when a seeming closed (solved) case is re-opened due to the discovery of new evidence pointing away from the original suspect(s). Other cases are cold when the crime is discovered well after the fact—for example, by the discovery of human remains. Some cases become classified cold cases when a case that had been originally ruled an accident or suicide is re-designated as murder when new evidence emerges.

Timothy John Evans (20 November 1924 – 9 March 1950) was a Welshman who was wrongly accused of murdering his wife (Beryl) and infant daughter (Geraldine) at their residence in Notting Hill, London. In January 1950, Evans was tried, and was c ...

tried for the crime. A case that goes to trial and does not result in a
conviction
In law, a conviction is the verdict reached by a court of law finding a defendant guilty of a crime. The opposite of a conviction is an acquittal (that is, "not guilty"). In Scotland, there can also be a verdict of " not proven", which is ...

In some cases, a suspect, often called a "person of interest" or "subject" is identified early on but no evidence definitively linking the subject to the crime is found at that time and more often than not the subject is not forthcoming with a confession. This often happens in cases where the subject has an
alibi
An alibi (from the Latin, '' alibī'', meaning "somewhere else") is a statement by a person, who is a possible perpetrator of a crime, of where they were at the time a particular offence was committed, which is somewhere other than where the crim ...
, alibi witnesses, or lack of forensic evidence. Eventually, the alibi is disproved, the witnesses recanted their statements or advances in forensics helped bring the subjects to justice.
Sometimes a case is not solved but forensic evidence helps to determine that the crimes are
serial crimes. The
BTK case and
Original Night Stalker (the latter pending trial as of April 24, 2018) cases are such examples. The
Texas Rangers have established a website in the hopes that it shall elicit new information and investigative leads.
Tunnel vision
Sometimes, a viable suspect has been overlooked or simply ignored due to then-flimsy circumstantial evidence, the presence of a likelier suspect (who is later proven to be innocent), or a tendency of investigators to zero in on someone else to the exclusion of other possibilities (which goes back to the likelier suspect angle)—known as "
tunnel vision".

DNA testing and other
forensics technology, many cold cases are being re-opened and
