Mexican armed forces killed Nemesio Rubén Oseguera Cervantes, known as “El Mencho,” during an operation Sunday in the western state of Jalisco, delivering a dramatic blow to the Jalisco New Generation Cartel and marking one of the most significant victories in the country’s long-running battle against organized crime.

According to Mexico’s Defense Department, Oseguera Cervantes was wounded during a military operation in the mountain town of Tapalpa, roughly two hours southwest of Guadalajara. He later died while being transported by air to Mexico City. The region has long served as a stronghold for the cartel, which authorities say is responsible for trafficking massive quantities of fentanyl and other drugs into the United States.

Troops came under heavy gunfire during the raid. Four individuals at the scene were killed in the confrontation, and three others — including Oseguera Cervantes — were wounded and subsequently died from their injuries. Two suspects were arrested. Security forces seized armored vehicles, rocket launchers and a cache of high-powered weapons. Three members of the armed forces were injured and are receiving medical care.

The death of the cartel leader triggered immediate retaliation across parts of Jalisco and neighboring states. Criminal groups erected roadblocks and set vehicles ablaze in an apparent effort to disrupt security operations, a tactic frequently used by cartels to hinder military movements and demonstrate territorial control.

Videos circulating online showed thick plumes of smoke rising over Puerto Vallarta, a popular Pacific coast tourist destination, while scenes of panic unfolded at Guadalajara’s airport as travelers hurried to exit terminals. Air Canada announced it was suspending flights to Puerto Vallarta due to what it described as an ongoing security situation, advising passengers not to travel to the airport until further notice.

Oseguera Cervantes had been one of the most wanted fugitives in the hemisphere. The U.S. Department of State had offered a reward of up to $15 million for information leading to his capture. The cartel he led, commonly known as CJNG, emerged in 2009 and rapidly expanded into one of Mexico’s most formidable criminal organizations.

In February, the Trump administration designated the cartel as a foreign terrorist organization, increasing pressure on Mexico to dismantle its leadership and financial networks. The killing of Oseguera Cervantes is likely to be viewed in Washington as a significant development in bilateral security cooperation.

Mexican President Claudia Sheinbaum has previously expressed skepticism about the so-called “kingpin strategy,” which focuses on eliminating cartel leaders. Critics argue that removing top figures can fracture criminal groups, unleashing violent turf wars. Nonetheless, security remains a pressing concern for her administration, particularly amid heightened scrutiny from U.S. officials demanding stronger action against fentanyl trafficking.

The Jalisco cartel has earned a reputation as one of the most aggressive criminal groups in Mexico. It has carried out brazen attacks on security forces, including ambushes of military convoys and assaults on helicopters.

The organization has pioneered the use of drones to drop explosives and has deployed land mines in rural areas to slow advancing troops. In 2020, it launched a high-profile assassination attempt in Mexico City using grenades and military-grade rifles against the capital’s then-police chief.

The U.S. Drug Enforcement Administration has described CJNG as rivaling the power of the Sinaloa Cartel, long considered one of Mexico’s most notorious trafficking networks. While Sinaloa has been weakened by internal divisions following the capture of key figures such as Ismael “El Mayo” Zambada and Joaquín “El Chapo” Guzmán, both now in U.S. custody, CJNG consolidated territory and expanded its international footprint.

Authorities say the group operates in all 50 U.S. states and is a major supplier of cocaine, methamphetamine and fentanyl.

Oseguera Cervantes’ involvement in drug trafficking dated back to the 1990s. He was convicted in 1994 in the U.S. District Court for the Northern District of California on heroin distribution conspiracy charges and served nearly three years in prison before returning to Mexico.

Over the past decade, he faced multiple indictments in the United States, including charges in the District of Columbia related to large-scale trafficking of methamphetamine, cocaine and fentanyl, as well as firearms offenses tied to drug operations. He was also accused under the Drug Kingpin Enforcement Act of directing a continuing criminal enterprise.

The U.S. government has repeatedly underscored the role of CJNG in fueling the fentanyl crisis, which has claimed tens of thousands of lives annually. The cartel’s sophisticated production and distribution networks have generated billions of dollars in illicit revenue.

In the immediate aftermath of Sunday’s operation, the U.S. government issued a security alert urging American citizens in Jalisco, Tamaulipas, Michoacán, Guerrero and Nuevo León to remain in secure locations due to ongoing military activity and potential unrest.

While the death of “El Mencho” removes one of the most powerful figures in organized crime, security analysts caution that the long-term impact remains uncertain.

Cartel succession battles or splintering factions could spark further violence in the short term. For now, Mexican authorities are portraying the operation as a decisive strike against a criminal empire that reshaped the country’s underworld over the past decade.
