October 15th, 2016. Pelican Bay State Prison, security housing unit, short corridor. A folded square of paper, no bigger than a postage stamp, slides under a cell door. The handwriting is small, tight, almost feminine. Three letters at the top, the number 13, and one word underneath, green light. Eight days later, 2,700 miles away, on a sidewalk in East Los Angeles, a man named Hector eats two bullets to the back of the head while walking his daughter to school.
The shooter is 19 years old. He has never met Hector. He has never met the man who ordered the killing. He has never been to Pelican Bay. He acted because a piece of paper told him to, and because if he didn’t, he’d be next. This wasn’t the cartels. This wasn’t MS-13. This was La Eme, the Mexican Mafia. A prison gang of fewer than 250 made members that controls every Latino street gang in Southern California, taxes every drug sale in every barrio from Bakersfield to the border, and runs the entire California prison system from inside concrete boxes the
size of a parking space. They don’t move weight across borders. They don’t have submarines or private jets. They have something more dangerous. They have absolute authority over 30,000 foot soldiers who will die before they disobey. This is the story of how 13 teenagers in a juvenile detention center in 1957 created the most efficient criminal organization in American history.
How a one-legged heroin addict named Joe Morgan, born in Croatia, became the godfather of Mexican-American organized crime. How a single piece of paper called a kite can travel from a windowless cell in northern California and end a life in Houston, Phoenix, or Chicago within a week. And why, despite what you’ve seen on television, La Eme is not a cartel.
It’s something the cartels are afraid of. You have to understand. Most people confuse the Mexican Mafia with the Sinaloa Cartel, the Zetas, CJNG. They are not the same thing. Cartels are businesses. They produce drugs. They move product. They exist in Mexico. La Eme exists in American prisons. La Eme doesn’t grow a single poppy or cook a single gram of meth.
What they do is tax everyone who sells those drugs on American streets. The cartels supply. La Eme collects. And if you don’t pay, you don’t sell. And if you don’t pay and you keep selling, you don’t breathe. To understand how this happened, we go back to 1957. Deuel Vocational Institution in Tracy, California.
A holding pen for the worst juvenile offenders in the state. Inside its walls, 13 young Chicano inmates gathered in a corner of the yard. The leader was a kid named Luis Flores, street name Huero Buff. He was 16 years old, blond-haired, sharp-eyed, and already a veteran of three different street gangs from the Hawaiian Gardens neighborhood.
He’d watched black inmates organize. He’d watched white inmates organize. The Mexicans got picked apart, robbed, raped, and run off the yard. Flores said no more. The 13 founders chose their number deliberately. M is the 13th letter of the alphabet. M for Mexican. M for Mafia. And the symbolism ran deeper than that.
13 would become the sacred number tattooed on knuckles, branded on backs, hand signed in every cell block. The number 13 would eventually identify any street gang anywhere in the Southwest as a Sureno, a soldier of the south subordinate to La Eme. Today, every Latino gang in Southern California that wears the number 13, every Sureno set from Florencia to 18th Street to the Mexican Mafia’s own tax collectors, every one of them ultimately answers to those original 13 kids in a yard in Tracy.
The first rules were simple, total loyalty. Blood in, blood out. No member could ever inform. No member could ever show weakness in front of another race. And critically, no member would ever be expelled. Once you were Eme, you were Eme forever. The only exit was death. By 1961, the gang had grown to over 300 members spread across the California prison system.
By 1965, they controlled the drug trade inside every major institution in the state. Heroin, mostly. Cooked, packaged, and smuggled in by wives, mothers, and corrupt guards. The profits weren’t huge, a few thousand dollars a month per prison, but the discipline was absolute. Then came Joe Morgan, and everything changed. Morgan was born in 1929.

His parents were Croatian immigrants. He grew up in Maravilla, an East LA barrio so Mexican that white kids learned Spanish before English. By the time he was 16, Morgan was already a stick-up man. At 17, he murdered the husband of a 32-year-old woman he was sleeping with, stuffed the body in the trunk of a car, and buried it in a shallow grave.
He served six years for that one. While in San Quentin, he lost his right leg below the knee in a construction accident. He walked the rest of his life with a wooden prosthetic and a slight limp that he turned into a kind of swagger. Joe Morgan, 6 ft tall, blue-eyed, one-legged, and the only white man ever fully accepted as a made member of the Mexican Mafia.
What Morgan brought wasn’t muscle, it was vision. He’d studied the Italian Mafia from a distance, read Mario Puzo, watched The Godfather six times. He understood that the strength of the Italian Cosa Nostra wasn’t violence, it was structure, hierarchy, the ability to project power outside prison walls. The Italians had their captains, their soldiers, their associates.
They had territories, taxes, and codes. Morgan looked at La Eme and saw a violent prison gang. He wanted to build a Mexican Cosa Nostra. By the time he died in 2005, he had. Morgan’s strategy was elegant. He recognized that nearly every Latino gang member in Southern California eventually went to prison, and once inside, they had to choose a side or die.
He decreed that every Sureno, every gang member from south of Bakersfield, would pay tribute to La Eme upon entering the system. They would protect Eme members. They would carry out Eme orders. And when they got out, they would tax their own neighborhoods on behalf of La Eme.
The drug dealers, the chop shops, the prostitution rings, all of it. 10% off the top, sometimes more. If a gang refused to pay, the gang got the green light. You have to understand what a green light means in this world. It’s not a metaphor. It’s an operational command. When La Eme green lights a person, a clique, or an entire gang, every Sureno in every prison and every street in America is authorized and required to attack on site.
No questions, no exceptions. A green light on a gang means that gang’s members can be killed in their cells, robbed in the yard, stabbed in the visiting room. The shot callers in every prison are notified through kites, through coded letters, through whispered messages on the visiting yard. Within 72 hours, a green light issued in Pelican Bay reaches Los Angeles County Jail, Folsom, Corcoran, Calipatria, and every county lockup in between.
In 1992, La Eme green-lighted the entire 18th Street gang for non-payment of taxes. Within 6 months, 18 of their members were dead. Within a year, 18th Street paid their back tribute had in hand and resumed business as good standing Sureños. That’s the power. A handful of men in solitary confinement can shut down a 30,000 member street gang with one piece of paper.
The kite system is the nervous system of the organization. A kite is a small, tightly folded letter, often written on toilet paper or rolling paper, using a code only Eme members can read. Some use a number cipher based on the Spanish alphabet. Others use a Nahuatl-based language that mixes ancient Aztec words with Pachuco slang.
Kites get smuggled in shoes, swallowed in balloons, hidden in legal mail, slipped during attorney visits, taped under tables in visiting rooms. A made member can write a kite at 6:00 in the morning and have a man killed in Las Vegas by midnight. The system has been refined for 60 years. It still works. Here’s where it gets interesting.
The federal government has known about La Eme since 1980. They’ve prosecuted dozens of members under RICO. They’ve recorded thousands of hours of wiretaps. They moved the worst of them to the security housing unit at Pelican Bay, built in 1989 specifically to break the gang. Pelican Bay’s SHU is a windowless, soundless, sensory deprivation facility.
Inmates spend 22 and 1/2 hours a day in a concrete cell measuring 8 ft by 10 ft. No phone calls. No physical contact visits. Mail screened. Communication, in theory, impossible. The architects called it the perfect cage. And yet, from inside that cage, the Mexican Mafia kept running California. How? Because the system has weaknesses.
Lawyers can visit. Attorney-client privilege protects communications. La Eme members began funneling kites through compromised paralegals and corrupt attorneys, some of whom were paid in cash, some in heroin, some in sexual favors arranged on the outside. Visiting rooms have blind spots. Female visitors, often referred to as old ladies or carnalas, became couriers.
They’d memorize messages, then deliver them to street-level shot-callers within hours of leaving the prison. The CDC, the California Department of Corrections, estimated in 2006 that a kite from Pelican Bay could reach any Sureno set in the United States within 4 days. Today, that number is closer to 24 hours.
To understand how this scales, you have to know about Cheyenne Cadena. Rodolfo Cadena, street name Cheyenne, was born in 1943 in Boyle Heights. He joined La Eme at 19 during a stint at the Duel Vocational Institution, the same place where it all started. By the early ’70s, Cadena was the most respected leader in the organization.
He was an intellectual. He taught himself history, political theory, even Marxism in his cell. He believed La Eme should evolve from a prison gang into a political and economic force. He brokered peace with rival gangs. He pushed for organization, education, and discipline among Mexican-American inmates.
Some called him the Mexican Che Guevara. The FBI called him the most dangerous prison gang leader in America. On December 17th, 1972, Cheyenne Cadena was inside the day room at Palm Hall, a maximum security wing of the California Institution for Men at Chino. He was meeting with members of Nuestra Familia, La Eme’s mortal northern Mexican rival, to negotiate a possible truce. The meeting was a setup.
Five Nuestra Familia members rushed him. They stabbed him over 60 times. They threw his body over a second-floor railing. He hit the concrete floor below and died within minutes. He was 29 years old. Cadena’s death triggered a war that has not technically ended. For over 50 years, La Eme, also called the Sureños, and Nuestra Familia, the Norteños, have killed each other on sight in every prison, in every jail, in every street where their territories intersect.
The rule is simple, north versus south, number 14 versus number 13, N for Nuestra, M for Mexican. The dividing line cuts through California at Bakersfield. Above the line, you’re a Norteño. Below it, you’re a Sureño. If you cross the line wearing the wrong colors, you die. After Cadena, Joe Morgan consolidated power.
He spent the late 1970s and the ’80s building La Eme into a true criminal corporation. He installed shot callers called llaveros, the key holders, in every prison and major neighborhood. He standardized the tax rate, 10% on drug sales for established gangs, 25% for newcomers. He authorized the production of a constitution, a written set of rules called the Eme Reglas.
Don’t deal with blacks unless approved. Don’t testify against another member. Don’t disrespect another member’s family. Don’t refuse a direct order from a brother. Violations meant a green light, no appeal. By 1990, the taxation system was generating an estimated $30 million a year flowing upward through the gang hierarchy to support imprisoned members, their families, and the leadership’s external operations.
The money funded lawyers. It funded escapes. It funded executions. And critically, it funded the gang’s ability to maintain absolute loyalty. A jailed Eme member’s family received monthly payments. His commissary was always full. His legal bills were covered. In exchange, he served the organization for life.
Here’s the part that television gets wrong. La Eme doesn’t run drugs across the border. They have no presence in Mexico. They don’t import cocaine or methamphetamine or fentanyl. What they do is far more efficient. They wait. The Sinaloa Cartel sends product north. The CJNG sends product north. The Mexican cartels need American distribution networks.
And those networks are Sureno street gangs. Every single one of them. From the Mexican Mafia’s perspective, they don’t need to take the risk of smuggling. They just charge rent on the entire distribution system. Every kilo of meth sold by a Sureno in Los Angeles pays a percentage to La Eme. Every house, every dealer, every corner.
The cartels grow the product. The Surenos move it. La Eme collects. In 2001, federal prosecutors estimated that La Eme controlled, through taxation, the activities of more than 50,000 street gang members across Southern California and into Arizona, Nevada, Texas, and as far east as Georgia. They estimated total annual revenue extracted by the gang at over $100 million and every dollar of that ran upward through a structure designed by Joe Morgan from a prison cell.
Morgan himself died on November 9th, 2005. Cancer. Federal Medical Center, Springfield, Missouri. He was 76. He’d been incarcerated on and off for over 50 years. When his death was announced, La Eme members across the California prison system held 3 days of silence as a mark of respect. No conflicts. No movement. No business.
Then, on the fourth day, business resumed. That was Joe Morgan’s real legacy. Not just an organization, a machine that ran without him. The federal government has tried everything to break La Eme. In 1995, the largest RICO case in California history targeted 22 Eme members. Most got life sentences. The gang barely flinched.
New members were promoted within weeks. The kite system kept running. In 2006, prosecutors indicted 40 members and associates. Same result. Each time the feds cut off a head, three more grew back. The structure Morgan designed was deliberately decentralized. No single boss, a council of senior members called the Mesa.
Each made member could authorize hits within his own sphere. No one man’s removal could collapse the whole. The most ambitious attempt to break La Eme came with the construction of the Pelican Bay Shoe itself. The theory was simple. If we isolate the worst of the worst in total sensory deprivation, they can’t run anything.
From 1989 through 2015, hundreds of suspected Eme members rotated through that facility. Some spent 20 years in solitary confinement. They got mail twice a week, screened. They got 1 hour of yard time, alone in a concrete dog run. And from those cells, they ran the largest prison gang in American history. The system worked because the gang adapted faster than the institution.
When phone calls were monitored, they moved to mail. When mail was screened, they moved to legal visits. When legal visits were watched, they moved to coded gestures during contact periods. The CDC eventually identified at least 12 distinct communication methods Eme members used to bypass the Shoe’s controls.
Even total isolation couldn’t sever the chain. In 2011, the Pelican Bay inmates organized one of the largest prison hunger strikes in American history. 30,000 inmates across California refused food. The strike’s leadership, four men, were all alleged Eme members in the Shoe. They had coordinated the action across 33 institutions, hundreds of miles apart, while in solitary confinement.
Their demands led in 2015 to a federal settlement limiting indefinite Shoe placement. Many of the original Eme members were transferred to general population. The gang’s power did not diminish. If anything, it grew because now the kite system had even more channels to run through.
In recent years, the federal government has scored some genuine victories. In 2017, an indictment in Los Angeles targeted dozens of Mexican Mafia members and associates operating in the county jail system. Wiretaps captured Eme members in custody directing tax collection, ordering assaults, and arranging drug deals in real time using contraband cell phones smuggled in through visiting rooms and corrupt staff.
One member was recorded directing a murder from his cell on a phone while officially in maximum security. Several deputies were indicted alongside the gang members. The pattern keeps repeating. The gang adapts. The institution catches up. The gang adapts again. The reason La Eme has survived for almost 70 years while the Italian Mafia families have been hollowed out and the cartels have splintered every 5 years is structural. La Eme members do not flip.
The omerta, the code of silence, is genuinely absolute. Federal prosecutors have offered witness protection, full immunity, new identities to Eme members facing life sentences. With rare exceptions, every offer has been refused. To inform is to mark your entire bloodline, your wife, your children, your siblings, your parents, everyone you love becomes a target.
And the gang has the reach to follow through, so they don’t flip, ever. The few who have, like Rene Boxer Enriquez, who cooperated starting in 2003, paid an extraordinary price. Boxer’s family had to be relocated. He himself remains incarcerated under permanent threat. He has testified that during his 20-year career in La Eme, he personally ordered or participated in over a dozen killings, taxed an entire region of Southern California, and never once feared the federal government.
The thing he feared, the only thing, was being labeled a no good by his own organization. The shame, the dishonor, the certainty of death, that was the real prison. What La Eme reveals about American organized crime is something most people don’t want to face. The most powerful criminal organization operating on US soil today isn’t headquartered in a mansion in Sinaloa or a back room in Brooklyn.
It operates from concrete cells in California state prisons, run by men in their 50s and 60s and 70s, who haven’t seen the open sky in decades. They have no aircraft, no yachts, no suitcases of cash on private jets. They have notebooks. They have lawyers on retainer. They have hand signs and coded letters and absolute control over every Latino gang member from San Diego to El Paso to Tucson to Las Vegas.
They took the model of the Sicilian Mafia, stripped away the romance, and reduced it to its purest functional form. Discipline, hierarchy, loyalty, death. The lesson of La Eme is that you cannot incarcerate your way out of an organized crime problem. For 67 years, the state of California has tried. They’ve built supermax prisons designed specifically to break this gang.
They’ve put its leaders in conditions the United Nations classifies as torture. They’ve prosecuted, sentenced, isolated, and tried to extinguish La Eme by every legal means available, and the gang is stronger today than it has ever been because the conditions that created it, generational poverty, mass incarceration of young Latinos, the absolute necessity of gang affiliation for prison survival, those conditions have not changed.
Every new prisoner becomes a recruit. Every recruit eventually goes home. Every home becomes a tax base. The cycle does not break. Joe Morgan understood this in 1970. He told a fellow Eme member in a conversation later relayed in court testimony that as long as there were prisons in California, there would be a Mexican Mafia.
As long as there were Mexicans in those prisons, there would be soldiers. As long as there were drugs on American streets, there would be tax revenue. He said it almost casually, like a man stating arithmetic. He was right. He’s been dead for over 20 years. The kites still go out. The green lights still get called.
The number 13 still rules every Sureno barrio in America. And somewhere tonight, in a windowless cell in Pelican Bay or Corcoran or Folsom, a man is folding a square of paper, writing three letters and a name, and sending out an order that will be obeyed before the sun comes up. That’s the real story of La Eme. Not the violence, the discipline.
Not the killing, the order. Not the prison, the system. A criminal organization built so efficiently that it outlived its founders, outlasted its prosecutors, and outsmarted the most sophisticated correctional system on Earth from inside the cage with nothing but a pencil and a code.
