Miguel Ángel Solano Ruiz, a retired Marine captain implicated in a major fuel-smuggling operation linked to the Navy, was arrested on Thursday night in Zapopan, Jalisco. Known as “Capitán Sol,” he is believed to have played a crucial role in orchestrating this illicit network, which has raised serious concerns about corruption within the Mexican Navy and the integrity of customs operations vital for national revenue.
His arrest comes after extensive investigations revealed a network that recruited both active and retired naval personnel to facilitate the illegal smuggling of hydrocarbons, allowing these operations to bypass necessary tax payments—a practice identified in Mexico as huachicol fiscal. Witness testimonies indicate that Solano exploited his influence to position associates in key maritime customs roles across crucial ports, such as Tampico and Ensenada, while also engaging in bribery of public officials to ensure the operations ran smoothly.
The Federal Attorney General’s Office (FGR) indicated that at 48 years old, Solano is the last significant figure remaining from the criminal organization previously run by the Farías Laguna brothers, both of whom held high-ranking positions in the Navy. His impending legal challenges include organized crime and tax evasion charges, which follow a larger investigation that first surfaced when authorities intercepted a vessel carrying ten million liters of diesel smuggled from Texas back in March 2024.
Authorities have been relentless in their pursuit of those involved in this corruption scandal. Vice Admiral Manuel Roberto Farías Laguna was apprehended in September 2025, while his brother Fernando remained at large until his capture in Argentina earlier this year. Solano’s lifestyle has raised further suspicions; his gambling losses alone amounted to over 52 million pesos, a significant discrepancy compared to his modest pension of 18,000 pesos a month post-retirement in 2018.
The investigation has extended internationally, leading law enforcement to locations in France, Greece, and Spain, which reflects the extensive reach of this corruption ring. Following months of surveillance, a search warrant for Solano’s property in the affluent Villa Verona neighborhood led to his capture. He has since been transferred to the Altiplano maximum-security prison, where he will await trial.
This situation underscores the ongoing battle against corruption at high levels within the Mexican government and military, raising vital questions about accountability and the safeguarding of public trust.
