Sureño groups are involved in many aspects of criminal activity including homicide, drug trafficking, kidnapping, assaults, carjackings, home invasions, and robbery. They are also heavily engaged in human trafficking of adults and children. My family, particularly my grandmother, has been victim to each of the above listed items that this group is known for.
Also known as Southern United Raza, Sur 13 or Sureños X3
Groups of loosely affiliated gangs that pay tribute to the Mexican Mafia (a US-based prison gang) while in U.S. state and federal correctional facilities.
The primary sources of income for Sureño gang members are the retail-level distribution of cocaine, heroin, marijuana, and methamphetamine, both within prison systems and in the community, and the extortion of drug dealers.
Sureños use the number 13—which represents the letter "M", the thirteenth letter of the alphabet—in order to mark their allegiance to the Mexican Mafia.

Although there are many tattoos used by Sureños, there is only one tattoo that proves or validates membership. The X3 tag can also be commonly spotted in graffiti.
The word Sureño or Sureña must be earned.

History of Modern Mexican Gangs in Los Angeles, CA
Mexican American street gangs originated in Los Angeles in the early 1900s as a result of various factors, including economic conditions and racial prejudice.
In 1957, the Mexican Mafia (or La Eme), California's first prison gang, was established by Luis "Huerro Buff" Flores and other East Los Angeles gang members, at the Deuel Vocational Institution.
The Mexican Mafia was formed, in part, for protection from other groups in the prison population, and recruited its members from Mexican American street gangs.
A rivalry subsequently developed between Mexican American inmates from Southern California and those from Northern California.
The Southern gang members viewed Mexican Americans from rural, agricultural areas in Northern California with contempt and considered them to be unsophisticated and weak
The Northerners considered those from Southern California to be overly Americanized.

A Dispute Over a Pair of Shoes
By 1967, La Eme was attempting to unify all Mexican American gangs in California, and a concerted effort was made to end rivalries between various groups and amalgamate them into the state's largest prison gang.
However, the rivalry between Northerners and Southerners was solidified by an incident in which a Mexican Mafia member in San Quentin State Prison fatally stabbed his cellmate—a Mexican American from Northern California—in a dispute over a pair of shoes.
The Northerners then formed the Nuestra Familia (NF) prison gang for protection from the Mexican Mafia, the Southern gang.

The Split Creates the Sureños ("Southerners")
To distinguish themselves from the agricultural workers from Northern California, Mexican Mafia (La Eme) members began to refer to the gang members who worked for them as Sureños, a Spanish term meaning "Southerners".
Although Sureños were established in 1968, the term was not used until the 1970s as a result of the continued conflict between the Mexican Mafia and the Nuestra Familia in California's prison system.

...and creates the Norteños
Inmates from Northern California who were affiliated with the Nuestra Familia became known as Norteños, or "Northerners".

When a Sureño is asked what being a Sureño means, members answer: "A Sureño is a foot soldier for the Mexican Mafia."

As a result of these prison wars, all Hispanic California street gangs align themselves with the Sureño or Norteño movements with very few exceptions.
Exceptions such as the Fresno Bulldogs, and the Maravilla gangs of East Los Angeles).

Due to its membership size, the Fresno Bulldogs is the only Hispanic gang in the California Department of Corrections and Rehabilitation that is able to remain independent.

Sureños' strongholds in Upstate California are usually in Santa Rosa and Modesto due to a high Mexican immigrant population in those cities.
Central Sureños and Upstate Sureños
Sureños in Los Angeles refer to their members in Central California as "Central Sureños" and Sureños refer to their members in northern California as "Upstate Sureños".
Most Sureños are of Mexican descent, but some Sureño gangs allow members from various other ethnic backgrounds to join their ranks, making Sureños multiethnic.
Meaning, they can be Asian.

They also favor blue or grey sport clothing, such as Los Angeles Dodgers, Los Angeles Rams and sometimes Los Angeles Lakers.
Upstate Sureños, however, wear Dallas Cowboys, San Jose Sharks and Oakland Raiders clothing.
There were a lot of noises, sounds, and what I take to be attempts at "intimidation" as I attempted to gather this post together. It is still happening right now as I type this, they feel frantic, that is a good word to describe the energy right now.
