The Crazy Story Of Twin Smugglers-Turned Informants Who Helped Run The World's Most Powerful Drug Operation

From 1998 to 2008, twin brothers Pedro and Margarito Flores ran a nearly $2 billion drug ring that swept Chicago and other major US cities.

That, among other illicit activities, just landed them 14 years behind bars.

But the sentence could have been much longer. Had they not cooperated with prosecutors, the brothers almost certainly would have spent the rest of their lives in prison.

After being caught in 2008, the twins became informants, giving information on an even bigger criminal - "El Chapo" Guzman, the head of the Sinaloa cartel, one of the the most powerful-drug trafficking organizations in the world.

Prosecutors portrayed them as some of the most valuable informants in history.

Originally sealed for the brothers' protection, their testimony recently became available to the public. The documents reveal fascinating details about how one of the largest Mexican drug cartels functioned.

In 2013, the cartel supplied 80% of the heroin, cocaine, marijuana, and methamphetamine flooding the streets of Chicago, according to the DEA. The Flores helped move $60 million of coke primarily through the Midwestern metropolis every month.

On many occasions, the brothers collaborated with the cartel, which used a wide array of creative methods for transporting cocaine and money from Central America into the US. They once even passed the operation off as a humanitarian aid project.

The Business

After slinging drugs in the US for several years, Pedro and Margarito, fearing arrest, moved back to Mexico in 2003 and 2004, respectively. But they set up an elaborate network that would allow them to sell cocaine in the US from Mexico, according to the testimony.

This network included three groups: cocaine and heroin suppliers in Mexico; a US crew; and about 30 wholesale customers across eight US cities: Chicago; New York; Washington, D.C.; Philadelphia; Cincinnati; Columbus, Ohio; Detroit; and Los Angeles.

Between 2006 and 2008 - what the Flores brothers considered "peak distribution" - the pair facilitated the transport and sale of approximately 3,300 to 4,400 pounds of cocaine every month. While wholesale value varies based on numerous factors including the location of the shipment, a kilogram, or about 2.2 pounds, in Chicago could easily run $30,000, according to their testimony. That's $60 million worth of cocaine each month.

How It Worked

Prior to late 2007, the Flores twins moved almost all of their drugs in semi-trucks and trailers with trap compartments in the roof.

After that, Pedro and Margarito started working with a man named Alfredo, who claimed to be a lifelong friend of El Chapo, even godfather to his son. On behalf of the cartel leader, Alfredo helped them transport cocaine from Colombia to Mexico in airplanes, submarines, and trains.

The Flores brothers soon agreed to establish legitimate shipping companies with Alfredo and his wife, which gave them a simpler method for transporting cocaine to the US. The brothers didn't want to run the businesses, but they invested $600,000 in startup money and agreed to pay $1,000 for every kilogram moved by train.

Once the cocaine arrived, the Flores brothers maintained several warehouse and "stash houses" in Chicago and other cities. There, the crews unloaded shipments of drugs for customers, and they counted and packaged the profits of those sales. All of the money went back to suppliers in Mexico.

Also, for a 3% to 7% fee, Alfredo's wife shipped cash profits from one location to another using both planes and cars. The shipments ranged from $100,000 to several million, according to the brothers' statements.

Alfredo also gave the brothers access to cocaine transported in 747s and submarines by El Chapo and other members of the Sinaloa cartel, like Ismael Zambada-Garcia, known as "El Mayo" or "Mayo Zambada."

They used the 747s with no seats to ship clothing to Central or South America as part of humanitarian aid projects. Once the planes arrived, workers unloaded them and replaced the clothes with up to 13 tons of cocaine for the return trip to Mexico, according to the testimony. After landing at Mexico City International Airport, El Chapo's paid contacts unloaded the cocaine and transported it out of the airport.

The process also often required smaller airplanes, submarines, tractor trailers, fishing vessels, speed boats, personal automobiles, and El Chapo's infamous tunnel system.

The Sinaloa Cartel Today

After a 13-year manhunt, Mexican marines finally caught up with El Chapo in February. (He escaped from a high-security Mexican prison in a laundry cart in 2001.)

El Chapo appeared on numerous lists of both the wealthiest and most wanted in the world. His bloody feuds with two other cartels, the Juárez and Los Zetas, have left nearly 80,000 people dead in the past seven years.

After El Chapo's capture, El Mayo reportedly took over the Sinaloa cartel. Despite his son's arrest in November, El Mayo remains at large, with unknown whereabouts.

"I knew that once the people I have talked about today found out I was cooperating, they would try to kill me and my family," Margarito, now in witness protection, said in his statement.
