Authorities describe armed confrontation
The Navy, the federal Security and Citizen Protection Secretariat and Sonora's Agency of Ministerial Criminal Investigation, or AMIC, carried out the operation following naval intelligence work. The deployment included two helicopters, another aircraft and personnel on the ground.
Officials said the ground teams encountered gunfire while approaching the site and fired back, killing the man they identified as Francisco "N," alias "El Meny Carranza." Reports differ on the timing: some date the arrests to October 24, while others place the deployment on October 23. They do not resolve whether officers or other civilians were injured, or what legal authorization supported the intervention.
Naval intelligence had reportedly followed Carranza during October through Magdalena de Kino, Ímuris, Arizpe and Cucurpe alongside Salú Francisco Hernández Tenorio, whose aliases include "El Ponchis" and "El Fantasma." That tracking narrowed the search to an area in Arizpe municipality. The reports do not establish that Hernández Tenorio was at the confrontation or was one of the four people detained.
The reported seizures included five long guns, two handguns, 45 magazines and an unspecified quantity of ammunition. Authorities also listed four vehicles, three ballistic vests and a bag of material resembling marijuana, without giving its weight. Prosecutors received the detainees and seized property and will determine the detainees' legal status. Neither their identities nor their individual alleged roles were disclosed.
Alleged role in Los Fantasmas
N+ and other news reporting identified the dead man as Francisco Manuel Romero Carranza and described him as the suspected second-in-command of Los Fantasmas, a Sonora-based criminal group. Reports cited a September 2024 intelligence assessment linking the group to Los Chapitos, a Sinaloa Cartel faction. His alleged position and affiliation remain attributed assessments rather than established findings.
La Razón de México reported that federal authorities had identified Los Fantasmas activity in Sáric, Tubutama, Trincheras, Santa Ana, Altar and Magdalena de Kino. Authorities cited that presence across Sonora as evidence of Carranza's regional significance.
Los Chapitos faces charges and shifting alliances
The organized-crime register NORN records Los Chapitos' presence in Sinaloa, Sonora, Baja California and Chihuahua. According to the register, an indictment unsealed on February 5, 2026, in the Southern District of New York charges the faction with importing fentanyl into the United States.
NORN also says the U.S. Treasury's Office of Foreign Assets Control designated Los Chapitos under Executive Orders 14059 and 13224 on June 9, 2025. That action blocked ten companies operating in real estate development, construction and hospitality. A subsequent action on May 20, 2026, targeted a laundering network that included a private security company and a restaurant business in Chihuahua.
Separately, an October 2026 analysis by academic Víctor Manuel Sánchez Valdés, reported by Infobae, said at least seven regional cells had distanced themselves from Los Chapitos. Among them were Sonora's Los Salazar, Los Paredes and Los Cazadores. According to the analysis, those three groups broke away over the fentanyl business, formed an alliance called Cártel Independiente de Sonora and collaborated with the rival La Mayiza faction.
Prison escape and outstanding searches
Carranza's death followed a months-long effort to recapture him. He was arrested on March 28, 2026, but escaped with two other inmates from Hermosillo's Cereso No. 2 prison on July 11. Authorities later offered a reward of up to one million pesos for information leading to his recapture.
According to La Razón de México, his reward notice listed allegations of criminal association, corruption of minors, attempted premeditated homicide with advantage against five people, unlawful deprivation of liberty and marijuana-possession offenses. It also listed attempted premeditated homicide against two people and aggravated kidnapping. The allegations do not establish convictions.
El Siglo de Torreón reported that two custodians and two surveillance commanders at the prison were arrested in connection with the escape on suspicion of aggravated prison escape.
After Carranza's killing, authorities continued looking for the two inmates who escaped with him, identified as "El Mike" and "El Güero," according to El Siglo de Torreón. The Sonora state prosecutor's office has also announced rewards for them.
