California Crime Stoppers

Bridging the gaps between the community and law enforcement to build safer neighborhoods through partnerships, training, and education

If you would like to become a member of the California Crime Stoppers Board of Directors or would like to volunteer, contact us.

Crime Stoppers began with a young detective, Greg MacAleese, frustrated by the number of unsolved cases, including the murder of Michael Carmen was working one night at a local filling station.  Two weeks passed and Detective had exhausted the many leads that came in on his investigations.  

He decided to look to the public for help.  With this objective in mind, and with the help of his agency, they turned to the community, the media and other law enforcement agencies in the area.  Together this new group of unrelated entities collaborated to form a partnership which allowed them to think “outside the box”.  This new partnership recreated the murder being investigated by the young detective, broadcast it on a local news program offering the promise of anonymity and reward compensation.  The case was solved within 72 hours.    

The person called in identifying a car leaving the scene at high speed and he had noted its registration. The person calling said that he did not want to get involved so he had not called earlier.

HOW IT WORKS

Detective MacAleese then realized that fear and apathy were the primary reasons why the public tended not to get involved. So he helped design a system where the public could anonymously provide details of the events. This system focused on stimulating community involvement and participation, taking advantage of every possible media opportunity, especially electronic media, to publicize unsolved crimes; and offering cash rewards for information leading to an arrest and/or conviction.

This was the birth of the first Crime Stoppers program taking place in Albuquerque, New Mexico, on September 8, 1976.   Since then, over half a million arrests have been made, close to one million crimes have been solved, over 75 million dollars in rewards have been paid and over 4 billion dollars in property and narcotics have been recovered. 

California Crime Stoppers is a non-profit organization that began in 1985 with programs throughout California uniting together to share, collaborate, and provide training on innovative ways to build and strengthen partnerships between communities and law enforcement.  Individual Crime Stoppers programs throughout the state came together as an association to provide annual and bi-annual training conference focusing on crime trends, technology, and methods to collaborate with communities.
