Cold cases are, by definition, “an unsolved criminal investigation (as of a homicide or abduction) that has stopped being actively pursued because of a lack of evidence.” Typically, after at least one year of investigation, a case may be filed as a cold case. The most common cases that go cold are homicides.

A case becomes “Cold” when all probative investigative leads available to the primary investigators are exhausted and the case remains open and unsolved after a period of three years. Cold Cases are reviewed to determine if newer technologies or forensic testing may produce any new potential leads.

What makes an unsolved case a cold case? A cold case homicide involves any investigation that remains unsolved after being reported to law enforcement and in which all significant and viable leads have been exhausted.

All states have some sort of freedom of information or public records law. Records requests are sometimes routinely denied on the grounds that a case is "open," but that might not be what the law says. Depending on the state, the agency might have to provide some records even for open cases.
