California Gang Investigators Association

The California Gang Investigator's Association was founded in 1977 to foster better relationships and networking among the various investigative units working street gangs in Los Angeles County and throughout the state of California.  Over the years the Association has grown to include members across the nation and in Australia and Canada.  Membership is limited to all law enforcement officers including corrections, prosecutors, parole, and probation.

The Association interacts with fellow Gang Investigator's Associations across the country to assist in a coordinated approach to gang investigations, training, and to foster exchanges of information.  The Association strives to better serve the needs of law enforcement by providing quality gang training that will assist members in the performance of their duties in a professional and ethical manner.  It is the hope of the Association that through professional and pertinent training our membership will be better prepared to meet the challenges presented by street gangs.

While the solution to the street gang problem remains elusive it will only be found  after a thorough examination of all aspects of the phenomenon.  The Association supports this examination and provides a forum for investigators to exchange ideas in order to provide a wide ranging base of knowledge to contribute toward a solution.

Gangs Fact and Fiction   -   To pose questions, email here

Michael Santini is the penname of a career special agent with Homeland Security Investigations. He previously served as a border patrol agent in San Diego, California. For his work as lead case agent on Operation Devil Horns, Michael received a distinguished service medal from the U.S. Attorney General. He has a master’s degree in criminal justice from John Jay College in New York.

In a bid to take down MS-13’s criminal network in the Mission District of San Francisco, Michael Santini, a special agent with Homeland Security Investigations, recruits a pair of hardened gang members and convinces them to risk their lives as criminal informants.

Through a combination of clever ruses and dogged determination, Santini tracks down the gang’s international network from the Bay Area streets and alleys, all the way to the prison cells in corrupt Central American regimes.

It's a thrilling story about a dedicated team of special agents and federal prosecutors -- in partnership with a few local cops -- who overcome major political and legal challenges to take down more than thirty violent criminal targets in a masssive sweep.

Operation Devil Horns offers a rare glimpse into the criminal subculture of MS-13, an international gang that terrorizes communities across America. The story illustrates how savvy police work and interagency cooperation can cut through politics to positively impact life-or-death crime fighting on the streets.
