The Mexican Mafia prison gang, also known as La Eme (Spanish for the letter M)
The Mexican Mafia prison gang, also known as La Eme (Spanish for the letter M) The Mexican Mafia prison gang, also known as La Eme (Spanish for the letter M), was formed in the late 1950's within the California Department of Corrections (CDC). La Eme is a loosely structured criminal organization with strict rules that must be followed by the estimated 350 to 400 members. Most members of La Eme are comprised of Mexican-American males who previously belonged to a Southern California street gang. La Eme is primarily active in the Southwestern and Pacific regions of the U.S., however, its' power base remains in California. The Mexican Mafia's main source of income is extorting drug distributors outside prison and distributing methamphetamine, cocaine, heroin and marijuana within the prison systems and on the outside streets. Some members of La Eme have direct links to Mexican DTOs and broker deals for both themselves and their associates. La Eme is also involved in other criminal activities including controlling gambling and prostitution within the prison systems.
