Nogales, Ariz. — U.S. Customs and Border Protection Office of Field Operations officers at the Nogales Port arrested a Mexican woman today for attempting to smuggle approximately $232,400 worth of black tar heroin, cocaine and methamphetamine into the United States.

Reyna Gisela Ramirez-Hernandez, 34, of Hermosillo, Sonora, Mexico, was referred for additional inspection of her Chevrolet van. During the inspection, a CBP narcotics detection canine alerted to the presence of drugs within the vehicle’s firewall/dash area.

The drugs and vehicle were seized. Ramirez was turned over to U.S. Immigration and Customs Enforcement’s Homeland Security Investigations.

Individuals arrested may be charged by complaint, the method by which a person is charged with criminal activity, which raises no inference of guilt. An individual is presumed innocent unless and until competent evidence is presented to a jury that establishes guilt beyond a reasonable doubt.

CBP's Office of Field Operations is the primary organization within Homeland Security tasked with an anti-terrorism mission at our nation’s ports. OFO officers screen all people, vehicles and goods entering the United States while facilitating the flow of legitimate trade and travel. Their mission also includes carrying out border-related duties, including narcotics interdiction, enforcing immigration and trade laws, and protecting the nation's food supply and agriculture industry from pests and diseases.

U.S. Customs and Border Protection is the unified border agency within the Department of Homeland Security charged with the management, control and protection of our nation's borders at and between the official ports of entry. CBP is charged with keeping terrorists and terrorist weapons out of the country while enforcing hundreds of U.S. laws.
