The wife of jailed Mexican drug lord Joaquín "El Chapo" Guzmán has been arrested in the US on suspicion of drug trafficking, US authorities say.
Emma Coronel Aispuro is charged with participating in a conspiracy to distribute cocaine, methamphetamine, heroin and marijuana.
In an indictment for alleged international drug trafficking, the Federal Bureau of Investigation has provided a rare glimpse into how Emma Coronel Aispuro, a dual US-Mexico citizen entered the world of Joaquin "El Chapo" Guzman.
Born in California in 1989, she met El Chapo as a teenager in 2007. They married two years later at the age of 18, when he was 47.
He is currently serving a life sentence in New York for drug trafficking and money laundering.
The 63-year-old is a former head of the Sinaloa cartel, which officials say was the biggest supplier of drugs to the US.
According to FBI Special Agent Eric McGuire, Ms Aispuro's family had a "historical friendship" with El Chapo as part of the notorious Sinaloa Cartel.
Ms Coronel Aispuro's father, Ines Coronel, was a Sinaloa Cartel member designated a "significant foreign narcotics trafficker" by the Office of Foreign Asset Control under the Kingpin Designation Act for trafficking with El Chapo.
He was arrested, along with her brother, in 2013 on narcotics and firearm charges in Mexico. They were sentenced to 10 years in prison.
She is due to appear in a federal court in DC via video conference, the US justice department has said, and will also face charges of conspiring with others to help her husband escape from prison in Mexico in 2015.
El Chapo escaped from Mexico's maximum-security Altiplano prison after his sons bought a property near the prison and a GPS watch smuggled into the prison gave diggers his exact location. He escaped by riding a specially adapted small motorcycle through the tunnel.
Court documents have also alleged that Ms Coronel Aispuro was involved in planning another prison escape for Guzman before he was extradited to the US in January 2017.
