CBP officers at the Anzalduas-Reynosa International Bridge encountered a 26-year-old male Mexican citizen driving a silver 2013 Volkswagon Golf on Saturday, August 10. The driver presented his Mexican passport with U.S. visa and was referred to secondary for a more thorough examination. Utilizing a vehicle non-intrusive imaging system, officers discovered packages of suspected narcotics concealed within the vehicle. CBP extracted 29 packages of alleged heroin weighing approximately 19.32 kilograms (42.60 lbs.) and 6 packages of alleged cocaine weighing approximately 6.92 kilograms (15.25 lbs.). CBP-OFO seized the narcotics, which have an estimated street value of $4,260,000 for the heroin, $488,000 for the cocaine and seized the vehicle as well.   Also on Saturday but at the Hidalgo-Reynosa International Bridge, CBP officers came in contact with a 21-year-old female U.S. citizen traveling with an infant male at the pedestrian lanes. The adult female presented a U.S. birth certificate for herself and for the baby, who she claimed was her son. The adult female and baby were referred to secondary for further inspection and document review and it was there that officers discovered that the baby was not related to the female and was in fact a citizen from Mexico without proper documents to legally enter or reside in the United States.   CBP-OFO arrested both travelers and the male was released to the custody of Homeland Security Investigations (HSI) agents for further investigation. The female will be presented before a U.S. Federal Magistrate on criminal charges for alleged violation of U.S. immigration law.
