# Mexico CJNG crackdown after mayor, influencer killings > Live situation record from CLSTR: https://clstr.news/situations/mexico-cjng-mayor-murder-crackdown > Updated: 2026-08-22T17:18:07.000Z. Sources: 215. Developments: 7. Federal forces captured Ramón Ángel Álvarez Ayala, alias “El R1”, on 30 July 2026 in Atotonilco el Alto, Jalisco, in a joint operation involving the Secretariat of Security and Civil Protection, the Mexican Army’s special forces, and the National Intelligence Center. He was transferred to the high-security Federal Social Readaptation Center No. 1 (Altiplano) and placed in preventive detention alongside associate Jesús Salvador Vela Salazar. Authorities identified R1 as the leader of the CJNG “Los R’s” cell and the alleged intellectual author of the 1 November 2025 murder of former Uruapan mayor Carlos Manzo Rodríguez; Security Secretary Omar García Harfuch noted the murder was likely ordered because the mayor’s anti-extortion actions were viewed as a “provocation”. The arrest is part of President Claudia Sheinbaum’s “Plan Michoacán for Peace and Justice”. In connection with the Manzo case, authorities report a total of 31 people have been detained. R1 is also linked to the 13 May 2025 killing of TikTok influencer Valeria Márquez in Zapopan. While R1’s son is suspected of being the mastermind behind the feminicide, he remains at large. On 1 August 2026, Iván Martín “N” was detained in Zapopan for his alleged participation in the attack. R1’s son has since denied involvement, claiming the accusations have “political motives”. Political fallout continues as the Morena party has disavowed ties to R1 and his brother, Roldán Álvarez, who was expelled from the party in November 2025. R1 has filed amparo lawsuits challenging his detention and potential U.S. extradition. ## Claims - Ramón Ángel “N”, alias “R1”, was detained in Atotonilco el Alto, Jalisco in a joint operation by SSPC and Mexican Army special forces.
