The U.S. Treasury’s OFAC sanctioned 21 people and 25 companies linked to Los Mayos on 29 September 2026, placing a fresh financial squeeze on a network that had been doing business in Baja California. Among the companies drawn into the action were firms tied to Marco Antonio Moreno Gómez Santelices, whose businesses had sold equipment and technology to police corporations and won public contracts.
That matters now because the sanctions did not land on a blank slate. Moreno Gómez Santelices was born in Tijuana on 9 February 1983 and was identified as the controller of Baja Fixer Group, Inteliproof Efficient, Private Equity Baja and at least six other companies founded from 2021 onward. Those firms were described as part of a group of security, real-estate and entertainment companies that the OFAC said laundered money for the Cártel de Sinaloa, specifically the Los Mayos faction led by Ismael Zambada Sicairos, known as Mayito Flaco.
The contracting trail is what makes the case hard to dismiss. Inteliproof Efficient and Private Equity Baja received contracts from governments of Baja California, and the companies accumulated 42 contracts in all, while Promociones CHF de Baja California, the commercial name used by Festivales Artistas Mobiliario y Asesoría, also obtained contracts from the Secretaría de Turismo estatal. Verónica Ayala said on MVS Noticias that Inteliproof Efficient received contracts from the Fiscalía General del Estado between 2022 and 2025, including a purchase of facial recognition software for the Dirección de Técnicas de Investigación.
Ayala also said the missing piece remains missing: MCCI did not establish that Inteliproof Efficient used that system for criminal purposes or accessed institutional information improperly. What it did establish is that the fiscalía estatal paid the company more than 200 million pesos between 2022 and 2025, and Zeta said Inteliproof Efficient received 40 contracts. The accounting still leaves open how much of that sum came from each year or each contract, but the scale alone shows why the sanctions reached beyond the U.S. border.
The same names keep recurring through the network. Silvia Beatriz Ocaña Palazuelos and Siria Solis Sánchez served as legal representatives for Inteliproof Efficient and Private Equity Baja, and Solis Sánchez, a former official in the presidency municipal de Mexicali, appeared in that role from 2026. United States authorities also linked the companies to Juan José Ponce Félix, alias el Ruso, and to Alfonso Arzate García and René Arzate García, whom they identified as part of the Cártel de Sinaloa machinery in Tijuana. The immediate consequence is not a courtroom date in the record here, but a sanctions regime that makes the companies far harder to move money through and leaves their Baja California contracts under a harsher light than before.
