From El Chapo’s sons, the Chapidito, moving against their godfather, Elmeo, to the Flores twins, whose cooperation helped bring down their own father, betrayal has become part of the game.
Even heirs like Ovidio Guzman have been accused of making moves that left their fathers exposed.
Wait till you see what comes later because a 2026 jailhouse letter from a top cartel heir reportedly reveals he had been planning his father’s capture for years.
For over 50 years, Ismael Elmo Zambada ran the Sinaloa cartel without spending a single day behind bars.
Ismael Mario Zambata Garcia is the longtime leader of the Zambata Garcia faction of the Sinaloa cartel.
According to the US State Department, Zambata Garcia is unique in that he has spent his entire adult life as a major international drug trafficker.
Yet, he has never spent a day in jail.
That record ended on July 25th, 2024.
And it was the son of his own partner who ended it.
Join Gurman Lopez is one of the so-called Chapitos, the four sons of El Chapo who inherited his business after the Kingpin was arrested in 2016.
According to the Drug Enforcement Administration, these sons grew up in the cartel.
Elmo watched them from the time they were children.
He maintained communication with them and by many accounts treated them with the respect owed to the heirs of the empire he had built alongside their father.
Zambada said he has known Guzman Lopez since he was a young boy, but the Chapidos had their own agenda.
Zambada is one of the most consequential traffickers in Mexican history, but he and El Chapo’s sons have had a fractious relationship since their father was extradited to the United States in 2017.
What was once a relationship built on mutual benefit and generational loyalty had quietly become something else entirely.
a tense coexistence between a cautious aging godfather and a younger generation known for extreme violence and recklessness.
The scheme that brought Elmo down was orchestrated with surgical precision.
US law enforcement officials had previously told CNN that Walkin Guzman Lopez had duped Zambata and orchestrated their arrest by making him believe they were flying to northern Mexico to look at real estate.
But the real story was far more sinister than a simple trick.
According to Zambata’s own account released through his attorney, Guzman Lopez had invited him to a meeting at a ranch just outside of Kuliaakhan on July 25.
The pretense was a gathering to help resolve political disputes.
Zambata recounts that Waqin Guzman Lopez, whom he has known since he was a child, asked him to attend a meeting to help resolve differences between political leaders in his state.
It was the kind of invitation a man of Zambata’s stature would accept without hesitation.
a routine affair with familiar faces in familiar territory.
When he arrived at the ranch, Zambada greeted several people.
The atmosphere seemed normal.
Then he spotted Guzman Lopez.
Zambada said Guzman Lopez gestured for him to follow him.
And trusting those involved, he followed without hesitation.
That trust, decades in the making, was about to be weaponized.
I was led into another room which was dark.
As soon as I set foot inside of that room, I was ambushed.
Zambata said a group of men then assaulted him, knocked him to the ground, and placed a dark colored hood over his head.
The violence of the abduction was staggering.
Zambata’s attorney laid it out plainly.
Waqin Guzman Lopez forcibly kidnapped my client.
He was ambushed, thrown to the ground, and handcuffed by six men in military uniforms.
And Waqin, his legs were tied, and a black bag was placed over his head.
From that dark room, Zambata was dragged to a pickup truck, driven to a landing strip, and forced onto a private plane.
Zambata said he suffered significant injuries to his back, knee, and wrists during the incident and was later driven to a nearby landing strip and forced onto a private plane.
On the plane, Guzman Lopez removed his hood and bound him with zip ties to the seat.
They flew directly to El Paso, where US federal agents took him into custody on the tarmac.
The man who had evaded every law enforcement agency on earth for half a century was delivered to his enemies by the son of his own partner.
A man he had known since birth.
A man whose family he had helped protect and enrich for decades.
And it wasn’t even a spontaneous act of treachery.
This was a coordinated operation.
A Homeland Security Department official told the Washington Post that Avidio, El Chapo’s youngest son, who had been extradited to the US in 2023, had contacted his older brother, Wakuin, from a US prison to plot the downfall of Zambada in an apparent effort to win favor with American authorities.
Two brothers, both sons of El Chapo, had conspired together to hand over the man who had co-founded the cartel with their father.
The fallout was catastrophic.
A power struggle broke out within the Sinaloa cartel, causing a surge in murders, femicides, and missing person reports.
Homicides in Sinaloa rose from 44 in August 2024 to 142 in September.
The swell of violence continued into the following year.
In 2025, 1,657 people were killed.
Meanwhile, the activist group Sabuos Guerreras estimates that the number of disappearances has reached 5,800 since July 2024.
Though that is likely an undercount.
The sons of El Chapo didn’t just betray Elmo.
They detonated the entire structure of one of history’s most powerful criminal empires.
And thousands of ordinary people paid the price for it.
Not every cartel son carries a gun.
Some carry a wire.
And sometimes the weapon that destroys a cartel boss isn’t a bullet.
It’s a phone call to the DEA.
Pedro Pete and Margarito J.
Flores were twin brothers from Chicago, who by their mid20s had become two of the most prolific drug distributors in the United States.
They dealt directly with El Chapo and the Sinaloa cartel, moving mountains of cocaine and heroin through America’s heartland.
But in 2008, they made a decision that would shatter their world.
They became government informants.
The seeds of that decision were planted in fear.
It started to feel as though the world was closing in on the twins, who both now had families of their own to think about.
Pete’s wife, Vivana, had just had a baby.
Jay, who had two daughters with his first partner back in Chicago, now had a son with Valerie, who was pregnant with his fourth child.
The walls were closing in on multiple fronts.
Federal investigations were widening and rifts were forming in the Sinaloa gang, pitting Beltron against El Chapo.
The twins, who prosecutors said always assued violence, weren’t sure they would survive a looming cartel war.
It was a TV documentary that tipped the scales.
One night in 2007, Jay was watching a documentary about the mobster John Gotti, who was betrayed by an underling who testified against his former boss.
Something clicked.
The twins reached out to federal authorities and began cooperating.
But their father, Margarito Flores Senior, was still in the game.
And when he found out what his sons had done, he was furious.
“You don’t know what they’re capable of.
” Margarito senior told the twins.
Those words turned out to be prophetic, but not in the way anyone expected.
The father, defiant to the end, made a fatal choice.
In 2009, he crossed the border back into Mexico despite US government warnings.
Soon after he went missing.
His burned out car contained an expletive laden message warning the twins to shut up.
His body was never found.
Margarito Flores senior was killed because his sons had decided to cooperate with the DEA.
The cartel didn’t distinguish between the informants and their family.
The father paid the ultimate price for his son’s decision to flip from prison.
The twins wrestled with the guilt.
The twins were guiltridden, but they also blamed their father.
He chose that life, Jay said.
And that’s the life that ruined our family.
The government credited the Flores brothers with helping the US understand the inner workings of the Sinaloa cartel, including details of killings, kidnapping, and the 747s, El Chapo, used to move drugs from Central America.
Their testimony was instrumental in building cases against some of the most powerful drug traffickers in the world.
They were reunited in 2015 for their sentencing in Chicago.
After both pleading guilty to drug trafficking charges, Jay cried as he told the judge, “I’m ashamed.
I’m embarrassed.
I’m regretful.
” He apologized for putting his family in harm’s way.
Pete asked for forgiveness, too, saying he was ready to take full responsibility for his life.
The judge sentenced them each to 14 years, but he also issued a warning that landed like a verdict of its own.
You and your family will always have to look over your shoulder, he told the brothers.
Anytime you start your car, you’re going to be wondering, is that car going to start or is it going to explode? One has adopted an assumed identity, reinventing himself as a suburban dad with a job that has nothing to do with the drug trade.
The other lives a very public life as a media cartel expert and a consultant to law enforcement, cashing in on his unusual expertise.
But the shadow of their father’s death follows them everywhere.
Two sons who decided to do the right thing, or at least the thing that would save their own skins, and it cost their father his life.
The murder of Edgar Guzman Lopez is one of the most brutal chapters in the history of Mexico’s cartel wars.
He was 22 years old.
He was the son of the most powerful drug lord on the planet, and his death was a direct consequence of a betrayal between men who had grown up together, men who were practically family.
Born in the Sinaloan countryside in the 1960s, the Beltran Leava brothers worked closely with their cousin Waqin El Chapo Guzman, the leader of the Sinaloa cartel.
During decades of smuggling, the relationship went beyond business.
Chapo and the Beltran Leva brothers came up together through the ranks of the Mexican drug trade in the early 90s, eventually forging an alien dere or blood alliance that united Sinaloa’s most powerful narcos in what became known as the federation.
Alfredo known as El Mocomo or the desert ant helped seal the deal by wetting one of Chapo’s cousins.
For years, the partnership was immensely profitable.
Arturo Beltran Leva and his four brothers worked as under bosses and security chiefs for the Sinaloa cartel leaders.
They handled security, moved product, bribed officials, and waged war against rival cartels on El Chapo’s behalf.
The Beltran Leva brothers were in every sense the muscle behind the Sinaloa throne.
Then in January 2008, everything changed.
Beltran Leva was arrested by the Mexican army special forces in Kuliaakan Sinaloa.
The arrest of Alfredo Elmo Belran Leva sent shock waves through the organization.
But it wasn’t the arrest itself that triggered the war.
It was the suspicion of who was behind it.
After authorities released Guzman’s son, Ivon Archivaldo from jail on a technicality, Arturo Beltran Leva’s fears were confirmed.
Guzman had provided the information leading to the arrest of his younger brother Alfredo.
War was declared and one of the first victims was Edgar Guzman Jakin Guzman’s son who was killed when he left a Sinaloa shopping center with his bodyguards.
The hit was savage.
The Beltran Leva brothers blamed their partner Waqin El Chapo Guzman for their brother’s arrest and in retaliation ordered the assassination of Guzman’s son, 22-year-old Edgar Guzman Lopez, which was carried out in a shopping center parking lot by at least 15 gunmen using assault rifles and grenade launchers.
The assassins fired nearly 500 bullets at the SUV, killing Edgar and his companion instantly.
This was not a random act of violence.
This was a message carved in blood sent from one cartel family to another.
Arturo Belt Tran Leva, the self-styled boss of bosses, had chosen the most devastating form of retaliation imaginable.
Murdering the son of the man who had betrayed his brother.
The aftermath was an inferno of carnage.
The death of Edgar Guzman Lopez led to Guzman unleashing his full wrath upon the Beltron Leva cartel, leaving 128 dead in June 2008 and 143 dead in July 2008.
Throughout the early years of the cartel war, some estimates suggest that over 7,200 killings took place in Sinaloa alone due to widespread gang violence and reprisals.
After this incident, the Beltran Leva brothers and their lieutenants defected from the Sinaloa cartel and allied themselves with the Gulf cartel and Los Zetas.
The Sinaloa cartel fractured violently and the wave of death washed over entire states.
The ensuing years saw a huge spike in cartel related violence that also spread to other parts of the country.
As for Arturo Beltran Leva, the man who ordered the hit on El Chapo’s son, his ending was equally dramatic.
On December 11th, 2009, Arturo Beltran Leva held a Christmas party at a house in one of the most luxurious gated communities in Quavaka.
He hired artists such as Ramon Ayala and Los Cadetes Delinares and more than 20 prostitutes to entertain his guests.
The Mexican Navy’s elite special forces unit surrounded the house and tried to capture him, but in the exchange of fire, he escaped.
5 days later, they found him again.
He was traced to another luxurious apartment community where a 90-minute shootout ensued.
About 200 Mexican Marines, two Navy helicopters from which Marines repelled, and two small army tanks surrounded the building complex where he was hiding.
Approximately 20 fragmentation hand grenades were used by Belran Leva’s gunmen to keep the navy from advancing into his position.
Arturo Belt Tran Leva and three gunmen were killed.
The boss of bosses, the man who killed El Chapo’s son, was gunned down by Mexican Marines less than two years after the hit he ordered on Edgar Guzman Lopez.
And the retribution didn’t end there.
Associates who allegedly murdered four relatives, a mother, siblings, and an aunt of one of the Marines involved in the shootout that killed Arturo were also arrested by Mexican authorities.
The killings, allegedly in retaliation for Arturo’s death, happened hours after the Marines funeral.
The cycle of sons killing fathers and fathers killing sons.
It never stops in the cartel world.
Edgar Guzman Lopez was a 22-year-old whose only crime was being born to the wrong father.
And his death ignited a war that killed thousands.
Part four.
Elmenito and the fall of El Mencho.
Nasio Oagera Cervantes.
El Mencho was one of the most feared drug lords in the history of organized crime.
We’re talking about someone that is almost at the same level as El Chapo Guzman and Elmo Zambada.
Former DEA chief of international operations Mike Vigil told CBS News.
He called Osaggera Cervantes one of the biggest drug capos in the history of drug trafficking around the globe.
Elmeno’s empire was built on a foundation of extreme violence and family loyalty.
He eventually climbed to the top of the criminal organization and founded the CJNG.
After several of his bosses were arrested or killed under his command, the CJNG became one of Mexico’s leading criminal organizations.
His son, Ruben Osaggera Gonzalez, known as Elmenito, was his designated heir and second in command.
Ruben Osagera, known as Elmanito, is the son of Nimsio Elmano Oaggera, the fugitive cartel boss of the Haliscoco New Generation Cartel.
The son served as the CJNG cartel’s second in command before his extradition to the US in February 2020.
Elmenito was not just a figurehead writing on his father’s name.
He was an active violent participant in the cartel’s operations.
Reuben Osagera ordered the killings of at least 100 people, personally shot and killed at least two people, and ordered subordinates to shoot down a Mexican military helicopter, killing at least nine people in 2015, prosecutors said.
But Elmanito’s capture and eventual extradition to the United States set off a chain reaction that would ultimately doom his father.
El Mencho’s son, Ruben Oagera, known as Elmanito, was sentenced in March 2025 to life in prison.
After he was convicted in the US on drug and weapons charges, the conviction sent a devastating message about what awaited Elmano if he were ever captured.
Elmenito led the Halisco cartel’s efforts to use murder, kidnapping, and torture to build the cartel into a self-described empire by manufacturing fentinel and flooding the United States with massive quantities of lethal drugs.
Former US Attorney General Merrick Garland said, “But beyond the symbolism, Elmenito’s imprisonment created a structural crisis within the CJNG.
At the time of El Mencho’s death in February 2026, it was revealed that El Mencho’s son being jailed in the United States broke the line of succession with his stepson Juan Carlos Valencia Gonzalez El Palon and only one of El Mencho’s brothers being family members most likely to be candidates as his successor.
The loss of Elmanito shattered the cartel’s succession plan and weakened the family’s grip on an organization that depended on bloodline authority to maintain discipline among its ranks.
And then there was the intelligence trail.
Elmanito’s trial and the testimony it produced helped American authorities build an increasingly detailed picture of the CJNG’s structure, operations, and critically the location and habits of its leader.
A former Mexican federal agent named Ivan Morales testified at Elmanito’s trial, providing devastating insider testimony.
A former Mexican federal agent who testified against the drug trafficker, son of the country’s most wanted man, was shot dead in the central state of Moros.
Authorities said Ivan Morales was a prosecution witness in the US trial of Reuben Oera Gonzalez, a leader of Mexico’s violent Halisco New Generation cartel, who was jailed for life by a Washington court in March.
The cartel killed Morales and his wife in revenge, but the information he and others provided could not be unspoken.
In February 2026, the walls closed in.
Mexican forces killed Nessio Oagera Cervantes, known as El Mencho, the leader of the Halisco New Generation Cartel in a high-risk operation in the western state of Haliscoco.
Security forces tracked El Mencho, one of the United States’s most wanted fugitives, to a property in the mountain town of Tapalpa after receiving intelligence linked to a close associate.
The raid was intense and chaotic.
Special forces backed by the National Guard military aircraft and helicopters sealed off the area before dawn on February 22nd.
Cartel gunmen opened fire as soldiers advanced.
Security forces returned fire, killing several suspected CJNG members.
El Mencho and members of his inner circle fled to a nearby wooded cabin complex where a second firefight erupted.
Soldiers eventually found a wounded Elmeno alongside two bodyguards.
The authorities airlifted him to a medical facility, but he died during the flight.
Osgara Cervantes had been wanted for years by the United States, which alleged that he and CJNG traffic large quantities of fentanyl and other drugs into the US.
At the time of his death, the State Department was offering a $15 million reward for information leading to his arrest.
The violence that erupted after Eleno’s death was unprecedented.
Reacting to the capture of Elmeno, cartel operatives set off a wave of violence across 20 Mexican states.
By Monday, authorities reported that at least 30 suspected gang members, 25 National Guard troops, and one civilian had been killed in the unrest following the operation.
Security forces arrested more than 70 people across seven states and recorded at least 85 cartel-related roadblocks on Sunday alone.
The cartel’s fury reflected its desperation.
With Elmanito already serving life in a US prison, and now Eleno dead, the CJNG had lost its top two leaders, father and son, and the organization’s future was thrown into chaos.
El Pelin was also acknowledged by security consultant David Saledo to lack influence among other cartel commanders.
The man who was supposed to inherit the empire was locked in a cell in Washington DC and the man who built it was dead on a military aircraft somewhere over Haliscoco.
Elmenito didn’t pull the trigger that killed his father, but his capture, his trial, the intelligence it produced, the succession crisis it created.
All of it left El Mencho more isolated, more vulnerable, and more exposed than he had ever been.
The son, who was supposed to be the shield, became the crack in the armor.
Part five.
Blood is never thicker than power.
The cartel world operates on one principle above all others.
power, not loyalty, not family, not blood, power.
And every story we’ve covered here illustrates the same fundamental truth that in the drug trade, the people closest to you are always the most dangerous.
Elmo Zambada survived every law enforcement operation for over 50 years.
He outmaneuvered the DEA, the CIA, and multiple Mexican administrations, but he couldn’t outmaneuver the son of his own partner, a young man he had watched grow up.
a young man he had trusted enough to follow into a dark room.
Zambata was betrayed by Guzman, the son of his former partner, El Chapo Guzman, the guy who he had known from the time he was a baby.
The Flores twins made a calculated decision to cooperate with authorities.
They saved themselves, but ignited a chain of events that consumed their father.
“You don’t know what they’re capable of.
” Their father told them, “They’re going to kill all of us.
” He disowned his sons.
In 2009, he crossed the border back into Mexico despite US government warnings.
He never came back.
Edgar Guzman Lopez, just 22 years old, was obliterated in a parking lot because his father, El Chapo, allegedly betrayed the Beltran Leva brothers.
The son paid for the father’s sins.
His assassination was carried out by Blow Genman outside a shopping mall in Kuliaakan.
Sinaloa as retaliatory measures against perceived Sinaloa betrayals that endangered Beltron family members.
And El Mencho, the founder of one of the most violent cartels in Mexican history, watched his empire begin to crumble the moment his son was extradited to the United States.
El Mencho’s 34year-old son, Ruben Osera Gonzalez, was sentenced to life in prison.
A move that criminal justice experts said sent shock waves through the cartel.
Without his heir, the line of succession was broken.
Without the line of succession, the organization’s internal discipline weakened.
And without internal discipline, the intelligence that ultimately led to Eleno’s death was always going to surface.
The Mexican drug war has claimed hundreds of thousands of lives.
It has destabilized entire regions and corrupted governments at every level.
And at the heart of so many of its most devastating chapters, the collapses, the betrayals, the blood baths, there is a son.
A son who turned informant, a son who orchestrated a kidnapping.
A son who was murdered to send a message.
A son whose imprisonment exposed his father to the forces that killed him.
In narco capitalism, there are no rules, no laws, and no bailouts.
It’s kill or be killed, and the potential for more violence in Mexico is real.
In this world, blood doesn’t protect you.
