          GRAND RAPIDS, MICHIGAN — U.S. Attorney Mark Totten announced that Adrian Romero Antunez (35), a Mexican national in the United States on a tourist visa, pled guilty to conspiracy to distribute five (5) kilograms or more of cocaine.  Romero Antunez was the final defendant to plead guilty in a transnational and interstate cocaine ring that centered around New Buffalo, Michigan resident Ivan Huerta Hernandez (33).  Through conduits in Mexico, Huerta Hernandez was supplied by sources located in Chicago, Illinois, including Romero Antunez.  Huerta Hernandez then distributed cocaine to dealers in West Michigan and Northern Indiana.

          “The guilty pleas in this case represent a significant victory against a transnational drug trafficking conspiracy,” said U.S. Attorney Mark Totten.  “My office is committed to combatting large-scale traffickers who bring these poisons to the Western District of Michigan.  This prosecution demonstrates the power of pooling the resources of federal, state, and local governments.  Drug trafficking organizations do not recognize political boundaries and we must continue to work together to combat drug trafficking organizations across Michigan, the Midwest, and the United States.”
