Drug use, vandalism and bicycle thefts were the gateway crimes committed by the fledgling gang. By recruiting new members, jump-ins and gang violence would soon help escalate their acts to more serious crimes, including murder.
Look around your jurisdiction. Do you have gangs with names such as "South Side Locos," "Sur 13," or "Kanpol?" Do you see graffiti such as "SSX3," "LA 13," "SoCal 13," or "V-XIII?" Or maybe you just have Florence (F-13), 18th Street (XV3), or Mara Salvatrucha (MS-13) active in your area. These are all signs of Sureño gang activity. But maybe this activity did not migrate to your city directly from California.
This non-California-born Sureño gang phenomenon is happening across the United States and has even infected our neighbors in Canada, Central and South America. Many pseudo-Sureños have never even been to Los Angeles or California. Even the illegal immigrants recently coming from Mexico, Guatemala, Honduras and El Salvador are now sometimes claiming to be "Sureños." These Central and South American pseudo-Sureños have even less understanding than the U.S.-spawned pseudo-Sureños do about what real Sureños are supposed to be. Sometimes they barely know that they are supposed to be at war with their enemies, the "Norteños." They don't understand what the North vs. South rivalry is all about.
When I travel around the country, I sometimes hear from local gang cops in whatever city I'm visiting that the Sureños are not really a big problem. They often describe Norteños and Sureños as "getting along." If this is what you think, either you are seeing these pseudo-Sureños want-to-bes who were recruited locally, or the California Sureños are there in so few numbers that they are forced to associate with their California rivals the Norteños to avoid being victims of your local gangs. When this happens, these mixed gang members will call themselves "Califas," the Calo word for California.
Real hardcore California Southsiders will seek out rivals and quickly mark their territorial turf claims with Sur 13. And your unsophisticated pseudo-Sureños will eventually be schooled by hardcore Sureños and Mexican Mafia prison gang members on Sureño codes of conduct. This is likely to occur when these pseudo-Sureños are eventually arrested and sent to jails and prisons.
