Mexican officials extradited the suspected drug trafficker known as the “Queen of the Pacific” to the United States on Thursday.

Sandra Avila Beltran was handed over at the Toluca airport outside Mexico City to U.S. marshals who took her to Miami to face federal cocaine-trafficking charges, the attorney general’s office said.

Avila had been acquitted of similar charges in Mexico and her defense argued unsuccessfully that meant she should not be extradited.

In June, a court granted the extradition so she could face the charges pending in the U.S., where prosecutors allege she also had links to cocaine seizures in Chicago. In 2001, U.S. agents intercepted a telephone call in which Avila allegedly asked for payment for 220 pounds (100 kilograms) of cocaine delivered in Chicago.
