Idalia Ramos-Rangel has been wanted for her alleged involvement with drug trafficking from Mexico to the United States since the mid-1980s. It is alleged that Ramos-Rangel, a high-ranking member of the Gulf Cartel, directs a drug-trafficking organization based in Matamoros, Mexico. That organization allegedly is responsible for the delivery of more than one-hundred kilograms of cocaine in Arkansas.
On May 2, 2013, a federal indictment was handed down by a Federal Grand Jury for the United States District Court, Eastern District of Arkansas, charging Ramos-Rangel with multiple drug offenses, including conspiracy to possess with intent to distribute more than five kilograms of cocaine, distribution of cocaine, and use of a telephone to facilitate a drug-trafficking crime. On that same day, a federal warrant was issued in Arkansas for Ramos-Rangel's arrest. On June 6, 2013, another federal warrant was issued for Ramos-Rangel's arrest following additional federal drug charges (superseding indictment) obtained for other members of Ramos-Rangel's conspiracy. Ramos-Rangel is also facing federal drug charges in Texas.
The federal indictments resulted from a large-scale investigation, codenamed Operation Dirty Bird, that disrupted cocaine and narcotics trafficking from Mexico to the United States. Multi-tons of cocaine and marijuana are alleged to have been trafficked and distributed throughout the United States, in connection with Ramos-Rangel's alleged drug-trafficking activities.
