El Monte Flores
El Monte Flores, also known as EMF, is a Mexican-American criminal street gang based in California. It is the largest Hispanic gang in San Gabriel Valley and one of the oldest in Los Angeles County. History 
Also known as EMF, the gang has had an estimated 1,000 members since it was formed in the 1940s. The gang claims South El Monte, El Monte, North El Monte, and Mayflower Village as its turf. The gang's name comes from the Barrio Las Flores, named for the flower field & nurseries in the El Monte area. El Monte Flores is now part of a larger organization and pays "taxes" or "tribute" to the Mexican Mafia or "La eMe," a powerful prison-based gang who controls the majority of Latino gangs in Southern California.

Culture
Even though El Monte Flores are a Sureño gang and use the number 13 (to denote the 13th letter, M, in the alphabet.) they are rivals with a variety of other Sureño gangs. Members usually tattoo the words, "Monte Flores", "El Monte F", "Flores", "EMF", "EMFxTMS" on them. XIII, X3, 13 and 3 dots are also seen with Sureño gang members and their colors are blue and gray. Like all Sureños once they are in the prison system they set aside their rivalry and unite under the Sureño Banner and are controlled by La eMe. Criminal activity
