Mexican Mafia (La Eme): U.S.-based prison gang and criminal organization

Structure and characteristics

La Eme is typically described as having a hierarchical, cell-like structure where respected long-term prisoners exercise significant authority. Members adhere to a code of conduct, recognize certain leadership figures, and use symbols and tattoos to signal affiliation. The organization enforces discipline, collects payments or 'taxes' from affiliated street gangs, and mediates disputes affecting its interests.

Activities and influence

• Drug trafficking and distribution networks linked to both prisons and communities.
• Extortion, protection schemes, and racketeering aimed at individuals and businesses.
• Violent enforcement, including ordering assaults to maintain control or settle scores.
• Coordination with Sureño street gangs and influence over recruitment and local operations.

These activities have made La Eme a target of federal and state investigations, including racketeering prosecutions that seek to disrupt its leadership and financial flows.

History and legal response

Originating in California prisons in the 1950s–60s, the Mexican Mafia grew as incarcerated leaders organized for protection and profit. Over decades its reach expanded into communities across the southwestern United States. Law enforcement responses have included segregation, gang management units, and RICO-style prosecutions designed to treat leadership and conspiracies rather than isolated acts.
