Retired agent Michael Harrigan served in the FBI for 22 years. He initially worked general criminal and terrorism cases in the Kansas City Division and was on the Attorney General’s Protection Detail and the Police Training Coordinator in the Washington Field Office (WFO). In this episode of FBI Retired Case File Review, he reviews the  Violent Criminal Apprehension Program (ViCAP), the largest repository of serial violent crime cases in the country, and the Highway Serial Killings Initiative. He was the unit’s chief and oversaw the development of the web database which allows client law enforcement agencies direct access to conduct independent analysis. He also provides case studies of several serial killers, including Samuel Little who may be the most prolific in U.S. History.

Later in his career, Mike Harrigan was assigned as the Supervisory Senior Resident Agent in Farmington and Gallup offices of the Albuquerque Division where he conducted and supervised criminal investigations involving homicide, sexual assault, kidnapping, missing persons and unidentified human remains and was responsible for all federal investigations on three Native American reservations. After a few years, he accepted an assignment in Quantico, Virginia to be the Chief of the National Academy (NA) Program. The NA is the leading national law enforcement executive leadership institution, graduating over 1800 senior law enforcement officers from every state and more than 40 countries. Before he retired in 2018, Harrigan was the Chief of the FBI Academy’s Firearms Training Program. He recently wrote a post on LinkedIn titled A Leadership Perspective of FBI Academy Firearms Training that is a must-read if you’re interested in applying for the FBI.
