Mission & Goals   |   Services   |   Legal Authority

Mission & Goals

The mission of the Investigative Support Crime Analysis Unit is:
To provide timely and valuable investigative assistance to law enforcement agencies for the purpose of identifying and locating victims and offenders of violent criminal behavior, through the identification, collection and analysis of diverse information.

  • Facilitate Investigations by Establishing a Single Point of Contact
    The Investigative Support Crime Analysis Unit provides a single point of contact for law enforcement investigators to request criminal investigative analysis services. As a result, duplication of investigative effort is avoided and the exchange of information is expedited.

  • Identify How Perpetrators Commit Crimes
    Crime analysts in the Investigative Support Crime Analysis Unit are trained to analyze and correlate information on how a perpetrator(s) commits a crime, or their "modus operandi(MO)". MO is collected from the current crime being investigated by law enforcement and compared to MO information identified in previously reported unsolved and solved violent crime cases. This process is designed to link crimes being committed by the same person(s) and thereby, assist agencies identify perpetrators.

  • Increase Multi-jurisdictional Cooperation
    Today's criminals are highly mobile and cross city, county, and state boundaries in order to commit their crimes. The Investigative Support Crime Analysis Unit's crime analysts notify investigators of possible multi-jurisdictional links between crime and criminals. The notification process is designed to facilitate communication and cooperation between law enforcement agencies dealing with similar types of crime and criminals.
