Guadalupe Fernández Valencia, alias ‘La Patrona’

Guadalupe Fernández Valencia, known as “La Patrona,” was one of the highest-ranking women in one of the most powerful drug trafficking organizations in the Western Hemisphere: Mexico’s Sinaloa Cartel. Active mainly between 2009 and 2014, she allegedly oversaw the smuggling of cocaine, heroin, methamphetamine, and marijuana from Mexico into the United States and operated key money laundering networks.

Fernández Valencia reportedly served as one of the most trusted operators within the Chapitos faction of the Sinaloa Cartel — run by the sons of Joaquín Guzmán Loera, alias “El Chapo.” Indicted on the same ticket that sent El Chapo to prison for life, she spent a total of eight years in detention.

What is Guadalupe Fernández Valencia’s story?

Fernández Valencia was born on October 29, 1960, in Aguililla, Michoacán, Mexico. She reportedly worked in factories when she was young and started dealing drugs after she became pregnant. By the 1990s, she had moved to California, where she was arrested and convicted of street-level drug dealing in 1998 and served a federal prison sentence in the United States. She was deported to Mexico after her release in 2007. 

Soon after that, she moved to Culiacán, Sinaloa, where authorities claim she started helping her brother, Manuel Fernández Valencia, import cocaine into the United States. Together, they leveraged their California connections for the Sinaloa Cartel. 

After Manuel was arrested in 2010, Fernández Valencia temporarily halted her trafficking activities, and moved her family to Guadalajara, in the western state of Jalisco. Two years later, after a visit from a cartel associate who may have been one of the Chapitos, she returned to Culiacán and resumed trafficking, expanding her reach into moving cocaine, marijuana, methamphetamine, and heroin across the US-Mexico border, according to her case files. She rose through the Sinaloa Cartel ranks, eventually reporting directly to Jesús Alfredo Guzmán Salazar, alias “Alfredillo”, one of El Chapo’s sons, as his chief lieutenant to help oversee the full drug distribution process from supply to delivery.

In 2013, US authorities indicted Fernández Valencia in Chicago alongside El Chapo and others. In November 2015, the US Treasury Department sanctioned her, and she was arrested in Culiacán, Sinaloa, in February 2016 — a month after El Chapo’s final capture — and extradited to Chicago in November 2017. She pleaded guilty in 2019 to drug trafficking and money laundering charges and was sentenced to 10 years in 2021. Due to time already served and cooperation, she was released in 2023 after serving approximately three years of her sentence.

What crimes was Guadalupe Fernández Valencia involved in? 

Fernández Valencia was allegedly a central player in the Sinaloa Cartel’s northbound drug pipeline, coordinating both the physical movement of drugs and the flow of drug money back to Mexico.

She was accused of importing, between 2009 and 2010, an average of 30 kilograms of cocaine into the United States per week, along with around 3,500 pounds of marijuana, relying on her established network of contacts in California. Between 2012 and 2014, she reportedly expanded her operation to include methamphetamine and heroin, paying people to smuggle loads in vehicles and through tunnels from Tijuana into the United States, a corridor long used by the Sinaloa Cartel.

US authorities also considered her to be the chief financial officer of the criminal organization’s money laundering operations. According to her indictment, drug proceeds collected in Los Angeles were delivered to stores with ties to currency exchanges in the city of Guadalajara, which charged a 3 percent commission plus exchange fees to transfer the cash to Mexico. Her workers would then collect the funds in Guadalajara and redistribute them. She was also accused of helping facilitate the movement of dirty money through bulk cash smuggling, structured bank deposits, wire transfers, and alternative credit-based systems. 

To protect the Sinaloa Cartel’s operations, Fernández Valencia and her associates allegedly used violence and intimidation, including bribing public officials, carrying out kidnappings and extortion, and threatening or using violence against rival traffickers and law enforcement.

Where did Guadalupe Fernández Valencia operate?

Fernández Valencia operated primarily out of Culiacán, Sinaloa, which served as her base and where she was ultimately arrested. The first offense to land her in jail, which was street-level drug pushing in Los Angeles, helped her develop an established network of contacts and customers. Under Alfredillo, she largely trafficked to Chicago and Southern California.

Her main smuggling corridor reportedly ran from Culiacán to Tijuana, and across the US border into California. Drug money flowed back in the opposite direction, funneled from Los Angeles through currency exchanges to Guadalajara.

Who were Guadalupe Fernández Valencia’s allies and enemies?

Fernández Valencia’s most significant alliance was with Alfredillo, one of El Chapo’s sons and a central figure in the Chapitos faction of the Sinaloa Cartel. She served as his lieutenant, according to prosecutors, and was his trusted second-in-command, overseeing operations across the entire drug distribution chain.

Her brother, Manuel Fernández Valencia, who introduced her to the Sinaloa Cartel and was himself a direct associate of El Chapo, was also an important family ally. Manuel was arrested in 2010 and later convicted and given a 27-year federal prison sentence. In October 2025, he reportedly returned to Michoacan, Mexico, after serving 14 years and providing information in the trial of El Chapo.

Another key associate was Jorge Mario Valenzuela Verdugo, alias “El Marito Choclos,” who was designated by US authorities alongside Fernández Valencia as another lieutenant to Alfredillo, who managed drug distribution in Culiacán and Guadalajara. He was found tortured and killed in Mexico in November 2017, when proceedings against Fernández Valencia and El Chapo were already underway.

In August 2010, Fernández Valencia’s nephew — Manuel’s son — was murdered by the Beltrán Leyva Organization operative, reportedly after being mistaken for El Chapo’s son, Ivan Archivaldo Guzman. 

Her most consequential rupture came from within: by pleading guilty and cooperating “substantially” with US prosecutors, she turned against her former bosses. A US district judge noted at sentencing that her cooperation placed both her life and the lives of her five children at serious risk.

Where is Guadalupe Fernández Valencia now?

Fernández Valencia was released in 2023 after serving just three years of her 10-year sentence and a total of eight years behind bars, with the remainder credited to time served. As a foreign national convicted of federal crimes, she was vulnerable to deportation to Mexico, where many of her former criminal associates remain at large.

Whether Fernández Valencia was deported back to Mexico or entered witness protection of some kind following her cooperation is unclear. 

Her former boss, Alfredillo, remains a powerful figure in the Chapitos.
