After Joaquin Guzman, also known as El Chapo, was recaptured, Guadalupe Fernandez Valencia, his alleged head of financial operations, was also arrested in Mexico.

Sputnik News wrote that Valencia, 55, also known as La Patrona or The Boss, was captured in the city of Culiacan in Sinaloa state. She reportedly transferred both drugs and money for the Sinaloa Cartel. She has been charged with money laundering and drug trafficking by U.S. authorities. Her extradition has also been requested.

Citing a police statement, La Patrona is reportedly headed to a federal prison where she will remain in custody until her legal status is determined. Valencia is the sister of Manuel Fernandez Valencia, another drug trafficker of the Sinaloa Cartel who is under U.S. custody at present.

The Sinaloa Cartel, which acquired its name from its home state, operates by smuggling cocaine from Colombia via Mexico to the United States, adds Sputnik News. El Chapo is the head of the organization. The drug cartel also produces and distributes Mexican marijuana, heroin and other illegal drugs in North America and Europe.

El Chapo previously escaped a maximum security prison in July 2015. He was recaptured on Jan. 8, 2016 in Sinaloa and is currently detained in Altiplanoplano.

According to VICE News, La Patrona was arrested on Feb. 9, 2016, according to a spokesman for the National Security Commission. The Commission previously stated that Valencia imported huge quantities of heroin, cocaine, marijuana and methamphetamine from Mexico into the U.S. A video of what appears to be the aftermath of Valencia’s arrest surfaced in local media, featuring police officers escorting a woman without handcuffs into a waiting police vehicle. The woman had dyed blonde hair and a leopard print shirt.

Valencia was arrested in 1998, where she finished a prison sentence in California. She returned to drug activities after her release. In November 2015, the U.S. Treasury Department labeled Fernandez as a “Foreign Narcotics Kingpin.” She was also described as a lieutenant for Alfredo Guzman, El Chapo’s son.

According to Jose Carlos Cisneros, an expert who investigated the role of women in the Mexican drug trade, Valencia was among the highest ranked females in the Sinaloa Cartel. Cisneros added that some women almost have the same power as El Chapo, although they prefer to focus on money laundering more and maintain a much lower profile.

More updates and details on La Patrona’s arrest and case are expected soon.
