According to the National Institute of Justice, a cold case is "any case whose probative investigative leads have been exhausted. In essence, this means a case that is only a few months old may be defined as being 'cold.'" Unfortunately, the number of cold cases each year continues to rise. Currently, there are more than 250,000 unsolved murders in America, and that number increases by roughly 6,000 new cases annually. Based on data from Project Cold Cases, some states had more difficulty than others in solving murders from 1980-2008. During that 28 year period, it was Michigan had only been able to solve 52% of murder cases, which was the worst in the country. Other places that had more difficulty than others in solving murders include Washington D.C. (53% of murder cases solved), Kansas (55% solved), Alabama (55% solved), and Vermont (57% solved).
