Public Assassination of Anti-Cartel Mayor in Michoacán Prompts U.S. Offer to Intervene Against Cartels

MICHOACÁN — On the first night of November, during Day of the Dead celebrations, the independent, anti-cartel mayor of Uruapan in Michoacán, Carlos Manzo, was assassinated in the heart of his city during a public festival. His bloody murder has underscored the deadly risks faced by local officials who may lack adequate protection from a state that critics say is corroded by corruption and penetrated by powerful cartel networks that, in some regions, have supplanted government authority. The killing intensifies urgent questions about political and police corruption, cartel impunity, and the scope of U.S.–Mexico security cooperation — with a response from the U.S. State Department today offering to “deepen security cooperation with Mexico.”

Manzo, a fiercely outspoken anti-cartel mayor who took office in 2024 as Uruapan’s first independent leader, was gunned down as he stood before crowds at the annual Day of the Dead candlelight celebration. Witnesses said gunfire erupted shortly after Manzo appeared onstage, holding his young son moments before the attack. The festival, known locally as the Festival de las Velas, drew hundreds of families to Uruapan’s central plaza — now transformed into the scene of Mexico’s latest high-profile political assassination, and a catalyst for nationwide outrage, as online protests surged and citizens called for demonstrations against cartel violence.

According to early reports, at least two suspects have been detained and one attacker was killed on site. Authorities asserted — despite the success of the attack — that Manzo had been under National Guard protection since December 2024, with additional reinforcements added in May 2025 following credible threats to his life.

In Washington today, the killing drew political reaction. “My thoughts are with the family and friends of Carlos Manzo, mayor of Uruapan, Michoacán, Mexico, who was assassinated at a public Day of the Dead celebration last night. The United States stands ready to deepen security cooperation with Mexico to wipe out organized crime on both sides of the border,” Deputy Secretary of State Christopher Landau, the former U.S. ambassador to Mexico, said in a statement shared online.

Federal Security Minister Omar García Harfuch said the gunmen “took advantage of the vulnerability of a public event” to carry out the attack, despite a standing security perimeter.

President Claudia Sheinbaum condemned the killing as a “vile” assault on democracy and vowed there would be “zero impunity.” Her administration convened an emergency security meeting and pledged that the investigation would reach the “intellectual authors” of the crime. Yet the murder has already ignited outrage across Mexico over the government’s failure to protect local officials in cartel-dominated states such as Michoacán, where extortion, assassinations, and territorial disputes continue to erode basic governance.

Manzo had publicly warned of his fate. “I don’t want to be just another mayor on the list of those executed,” he said earlier this year, as he pressed the federal government for better coordination between municipal and military authorities. For years, Uruapan — an agricultural and trade hub in western Mexico — has been the site of deadly clashes between the Jalisco New Generation Cartel and remnants of the Knights Templar Organization, both vying to control lucrative extortion and drug routes.

The killing of Manzo fits a dark and familiar pattern. In 2025 alone, several mayors in Michoacán, Guerrero, and Tamaulipas have been killed in attacks widely attributed to organized-crime groups. In June, the mayors of Tepalcatepec and Tacámbaro were ambushed and slain while traveling in official convoys. More than 90 local officials have been murdered since 2018 — a rate that analysts say reflects how cartels target municipal governments to ensure political control over territories tied to narcotics, mining, and agriculture. Uruapan, at the heart of Mexico’s avocado belt, is a strategic prize for the cartels that tax every shipment leaving the region.

The mayor’s death also recalls earlier tragedies that scarred the nation. In 2012, Dr. María Santos Gorrostieta Salazar, the former mayor of Tiquicheo, was abducted and murdered after surviving two assassination attempts and defying cartel threats. Her death became emblematic of the dangers faced by reformers who refuse to cooperate with criminal groups. More than a decade later, Manzo’s murder illustrates that little has changed — except the brazenness of the attackers, now willing to strike in front of cameras and families celebrating one of Mexico’s most sacred holidays.

The killing has also reignited long-standing U.S. frustration over Mexico’s inability to stem cartel violence, even as the Trump administration has expanded counter-narcotics operations at the border. Under Trump’s renewed directives, the U.S. has classified several Mexican cartels as foreign terrorist organizations and empowered the Pentagon to develop strike options against high-value targets abroad. A September 2025 joint statement between Washington and Mexico City pledged deeper intelligence sharing and cross-border enforcement initiatives, including efforts to halt arms trafficking southward.

However, Mexico’s government remains deeply wary of any U.S. military involvement on its soil. President Sheinbaum has warned that “Mexico will not stand for an invasion in the name of counter-cartel operations,” rebuffing Republican calls for unilateral action. Her position lays bare a long-standing tension between Mexico’s need for U.S. support and its insistence on sovereignty — a fault line that Manzo’s killing has reignited.
