Fighting between the Jalisco New Generation Cartel and Mexican security forces raged on in a number of states Monday, fueling fears among many that there will be more violence to come.

Maria Dolores Aguirre`s family corner store has lived off tourism that has flowed into her charming cobblestoned town of Tapalpa, tucked away in the mountains of Jalisco state.

That was until gunshots erupted and helicopters flew overhead as the Mexican army killed the country`s most powerful drug lord, just a few miles from her home.

Now, the 50-year-old Aguirre worries that the bloodshed will deal a blow to her livelihood and change towns like hers. It is something many in the western Mexican state are grappling with, from its Pacific Ocean beaches to its capital Guadalajara that will host matches in June for the 2026 FIFA World Cup.

"It`s going to affect us. It`s collateral damage," Aguirre said. "The government is going to have to have a lot of security. ... The entire world just saw what happened and, of course, people are going to think twice about coming."

Fighting between the Jalisco New Generation Cartel and Mexican security forces raged on in a number of states Monday, fueling fears among many like Aguirre that there will be more violence to come.

More than 70 people died in the attempt to capture Nemesio Oseguera Cervantes and its aftermath, authorities said Monday. Known as "El Mencho," he was the notorious leader of the Jalisco New Generation Cartel, one of the fastest-growing criminal networks in Mexico, known for trafficking fentanyl, methamphetamine and cocaine to the United States and staging brazen attacks against Mexican government officials.

The White House confirmed that the U.S. provided intelligence support to the operation to capture the cartel leader and applauded Mexico`s army for taking down a man who was one of the most wanted criminals in both countries. The U.S. State Department had offered a reward of up to $15 million for information leading to the arrest of "El Mencho."

Oseguera Cervantes died after a shootout with the Mexican military on Sunday. Mexican Defense Secretary Gen. Ricardo Trevilla said Monday that authorities had tracked one of his romantic partners to his hideout in Tapalpa. The cartel leader and two bodyguards fled into a wooded area where they were seriously wounded in a firefight. They were taken into custody and died on the way to Mexico City, Trevilla said.

In the aftermath, a sense of unease simmered in tourist towns.

The Pacific Ocean resort city of Puerto Vallarta also was hard hit by cartel reprisals, frightening tourists.

Steve Perkins, 57, was visiting Puerto Vallarta with his wife Gayle and some friends. They were on their hotel room`s terrace when explosions and black smoke started appearing around the city Sunday morning.

Their return to Broken Arrow, Oklahoma, was delayed when their flight was canceled Monday and they were rebooked for March 1.

Perkins and his wife have been taking annual trips to Puerto Vallarta since 2012 and have always felt safe, until now. He said they don`t plan on returning to Mexico.

"There`s a lot of Americans trapped here," Perkins said.

Back in Tapalpa, Aguirre worked next to her son from the small neighborhood shop her family has owned for 50 years. The 15-year-old`s classes were canceled due to the violence.

Aguirre said it was unclear who exactly was in control of the area surrounding her: the military or the cartel. The other question on her mind was if this was just a one-off, or if there was more violence to come.

"We don`t know if these people (cartel leaders) are permanently here or not," she said. "If they really did kill this leader, it could be that they fight between each other to win control or see who will lead it."
