Google Your Gangsta'

Aili Malm, who joined the CSULB family in 2006 is developing a new technique that can track where criminals (most importantly criminals in organized gangs) are located through maps.
Her technique includes using e-mail, cell phone records and where crimes were committed to pin point criminals.
So far her discoveries conclude that the major players in organized crime tend to not live in the center of the action but farther away (still close to enough to maintain control).
