This FBI file concerns the Mexican Mafia, also identified as 'La Eme' and 'La Mafia', in California prisons and on the streets. The Bureau treated the group as an extremist matter and circulated intelligence alleging possible rebellion, insurrection, and seditious-conspiracy concerns, while also sharing material with the Secret Service and U.S. Attorney. Released records from 1973 and 1974 include a San Francisco letterhead memorandum, prison-source reporting, dissemination records, and teletypes about violence and gang conflict at San Quentin Prison. The documents describe the FBI's effort to collect information through sources at California correctional institutions and report alleged alliances, narcotics activity, prison disturbances, stabbings, and conflict involving the Mexican Mafia, Aryan Brotherhood, Black Guerrilla Family, and New Family.
