Unsolved/Cold Cases

On June 6, 2018 the Washington Post reported that out of 54,868 homicides in 55 cities over the past decade, 50 percent did not result in an arrest.  Due to the nature of reporting in the United States, it is difficult to determine the actual number of unsolved homicide cases for any specific period of time but the number would be staggering. Agencies face numerous challenges with unsolved cases, especially if all probative investigative leads are exhausted.

Cases in which all investigative leads have been exhausted can benefit from an independent behaviorally-based analysis.  The FBI refers to this process as criminal investigative analysis. Criminal investigative analysis is defined as the analysis of a criminal act by assessing the offender's behavior for the time period before, during and after the commission of the crime.  An essential component of this process is the behavioral analysis of the interactions between the offender and the victim.  An independent review of the case file from a behavioral perspective can provide the investigating agency with new investigative avenues designed to successively resolve the case.
