A girlfriend’s visit helped Mexican authorities close in on one of the world’s most wanted drug traffickers, Nemesio Oseguera Cervantes, widely known as El Mencho, a cartel boss whose capture had long carried a United States reward of up to $15 million.

Mexican military officials said intelligence operatives tracked a close associate of one of Oseguera’s romantic partners to a property in Tapalpa, a mountainous town in the western state of Jalisco.

Surveillance confirmed that the woman met with the fugitive leader inside the building and left soon afterwards, giving security forces confidence that he remained at the location.

According to Mexico’s defence secretary, Ricardo Trevilla Trejo, the information triggered a rapid operation involving the army, National Guard and air force, supported by intelligence cooperation with the United States.

Troops moved to arrest the cartel chief, but members of his security detail resisted fiercely.

Officials said the group fled towards wooded terrain on the outskirts of Tapalpa and opened fire on the advancing forces, even targeting a military helicopter that was forced to make an emergency landing.

Oseguera was wounded during the confrontation and died while being transported by helicopter to Mexico City, Trevilla said.

Several members of his inner circle were also killed or later died from their injuries, while others were captured.

The killing removes the long-time head of the Jalisco New Generation Cartel, one of the most powerful criminal organisations in Mexico and a major supplier of fentanyl, methamphetamine and other drugs to the United States.

For years, Oseguera had been among the most sought-after fugitives in the world.

The US government circulated wanted notices offering a reward of up to $15 million for information leading to his arrest or conviction, reflecting the scale of his alleged role in trafficking narcotics across North America.

The operation is being seen as a major moment for Mexican president Claudia Sheinbaum, whose administration has faced strong pressure from Washington to intensify action against organised crime groups blamed for the flow of fentanyl into the United States.

However, the aftermath quickly exposed the risks that often follow the fall of a powerful cartel leader.

Violence erupted across parts of western Mexico as suspected cartel members set vehicles ablaze, blocked highways and attacked businesses in apparent retaliation.

Authorities in Jalisco reported dozens of incidents affecting roads, shops and financial institutions as security forces moved to restore order.

Security officials also reported deadly clashes between gunmen and government forces in several locations.

Analysts say the death of Oseguera could reshape Mexico’s criminal landscape. While his removal deals a blow to the cartel he built into a global drug trafficking network, it may also trigger internal struggles or splinter groups competing for control of its lucrative routes.
