Based on the number of homicides and clearance rates for murders 2009-2012 this figure is either closer to, or well over 200,000. As of 2004 the United States also had approximately 14,000 unidentified sets of human remains, many of which could be homicides, further increasing our total number of unresolved cases.The efforts to resolve some of these cases by law enforcement and others have been unrelenting.
