It is one of the largest affiliated "tributary" gangs of the Westside Mafia, and is composed of roughly 1,700–2,200 members known as "made men", and thousands of more associates. There is a well-defined hierarchy, and violators alongside dropouts or defectors are often dealt with death or extortion. The Trillizos have been involved in numerous high-profile incidences, including the infiltration of local government bodies and police forces, and targeted assassinations against court witnesses, police officers, judges, and lawyers.
