But the high-profile federal prosecution in New York is a largely symbolic victory for authorities in Mexico and the United States, where the cartel — based mostly in the Mexican state of Sinaloa — continues to control most major narcotics markets.
“The Sinaloa cartel is still basically operating with the same power and reach,” said Mike Vigil, former chief of international operations for the US Drug Enforcement Administration. “They continue to be the most powerful drug organization in the world.”
Guzmán, a founding father of the cartel named for his home state, was captured in Mexico in January 2016 and extradited to the United States a year later.
But his criminal enterprise, which has long benefited from a more horizontal leadership structure he helped put in place, has continued to prosper, experts said.
In his absence, the cartel’s day-to-day operations have been largely handled by Ismael “El Mayo” Zambada, a longtime associate of Guzmán’s.
At trial, defense lawyers argued that Zambada — who was also named in the superseding indictment against Guzmán — bribed the Mexican government to frame El Chapo and remain free to run the cartel.
“El Mayo Zambada and Sinaloa have continued and thrived and flourished,” said Bruce Bagley, a University of Miami expert on Mexico’s cartels who has followed the trial.
“The fact that you knock off a kingpin like El Chapo — which he clearly was — does not mean that you end the organization or in any way severely debilitate it.”
The sensational 2½-month trial featured stunning testimony about corruption at nearly every echelon of Mexico’s government, from police and military commanders to local and state officials to former presidents who vehemently denied the allegations.
That corruption did not end with Guzmán’s capture. It still greases the cartel’s successful operations.
“It’s a confirmation of the massive widespread bribery and points to the difficulty the US government under (Presidents) George W. Bush, under (Barack) Obama and now (Donald) Trump have in finding workable partners,” Bagley said.
“With or without El Chapo, these lines of bribery, these lines of corruption, extend into every political party at every level of the Mexican government.”
Ray Donovan, the DEA special agent who spearheaded the 22-agency effort that led to Guzmán’s capture, told CNN that the Sinaloa cartel still supplies the vast majority of US drug markets.
“In fact, Chapo’s sons are now risen through the ranks of the Sinaloa cartel and taken over Chapo’s end of the organization,” he said.
Bagley said Guzmán and Zambada have allowed greater autonomy to an estimated 120 smaller cartel-affiliated organizations called “cartelitos.” That has made keeping track of them harder for law enforcement authorities.
The cartel also has an emerging rival
“It’s a symbolic victory,” he said of Guzmán’s prosecution. “It’s not going to affect the future of Sinaloa. The bottom line is that there are a lot of other people waiting in the wings. The jockeying has already begun.
Zambada, in his 70s, is considered the last of the old-school Mexican drug capos.
“He is very respected by the rank and file of the Sinaloa cartel and other cartel leaders,” said Vigil, who spent more than a dozen years working with the DEA in Mexico and along the border.
“He’s not in the best of health and if Mayo Zambada dies or if he’s captured, that will severely cripple the Sinaloa cartel because Chapo Guzmán’s sons have never gotten their hands dirty. They’re what we call ‘narco juniors.’ They’re good at spending their father’s money but are hardly capable of running the cartel.”
And Sinaloa has a formidable rival. The Jalisco New Generation cartel has been one of the world’s fastest-growing drug organizations since its split from Guzmán’s group in 2010, according to a DEA assessment. Rubén Oseguera Cervantes, known as “El Mencho,” is its leader.
Experts say the one certainly of Guzmán’s downfall is more drug violence.
“There’s going to be more bloodshed,” Bagley said. “Every time there are these transitions … there is a period of adjustment. It’s often quite bloody, but they sort things out because they have every incentive to do so.”
