Mexican Mafia ("La EME")
One of the first prison gangs to develop in the United States, the Mexican Mafia began in 1957 in California where a few dozen Latino convicts banded together at Deuel Vocational Institution under the leadership of Luis 'Huero Bluff' Flores. By 1961, the Mexican Mafia exercised so much control over Deuel that administrators attempted to transfer some members to San Quentin Penitentiary, which helped spread the gang to other prisons in California. The Texas chapter of the Mexican Mafia was founded in a Huntsville prison in 1984. The founder of La Eme was serving three life terms for murder conspiracy and racketeering when he was given permission by the California chapter to establish his own branch in Texas. There he wrote the constitution that is followed by members to this day, and continues to collect and manage revenue generated by criminal activities. The organization has always enforced a strict rule against homosexuality, reading the bible, disrepsecting other members, or publicizing a member's connections with others. Membership is for life, and the blood-in blood-out doctrine applies. As a previous spiritual leader of the Mexikanemi Science Temple of Aztlan, the founder of La EME followed a pre-Hispanic creed that related his desire to establish a legitimate network built on "character," and an emphasis of love over hate. However, police claim the actual objective of the Mexican Mafia is to earn money through criminal operations.
