Tulsa, OK - The last of seven illegal aliens from Guatemala was sentenced for working together and being paid to smuggle illegal aliens into the United States from Guatemala, Mexico, and other countries in Central or South America, including Asia.

From October 2021 through April 2025, the ringleader, Cidia Marleny Lima Lopez (Cidia), conspired with the defendants and other individuals throughout the United States, Guatemala, and Mexico to conceal, harbor, and transport unlawful aliens in the United States. Those aliens were from various countries in Central America, South America, and Asia.

Court documents show that Cidia used a social media application to coordinate payment to conspirators in Guatemala in exchange for transportation. The aliens were transported from Guatemala and housed in Mexico until they could cross the United States-Mexico border unlawfully. Once inside the United States, drivers and stash house operators in Oklahoma, New Mexico, and Texas would conceal the alien. Cidia admitted that the drivers would collect payment at her direction and transport the aliens to various stash houses in Oklahoma, Alabama, Arizona, Arkansas, California, Colorado, Florida, Georgia, Indiana, Illinois, Kansas, Kentucky, Maryland, Michigan, Missouri, Nebraska, New Jersey, New Mexico, New York, North Carolina, Oregon, Pennsylvania, South Carolina, Tennessee, Virginia, and Washington.

The indictment filed in April 2025 alleged that each alien would pay roughly $5,000 to be smuggled into the United States. All money collected from the aliens being transported was deposited into bank accounts accessible to Cidia and others. She then admitted to using those funds to purchase vehicles and real estate property. Court records show that Cidia forfeited three trucks and two ATVs that were seized during the execution of a search warrant in Oklahoma City on April 24, 2025. Additionally, Cidia is forfeiting all interest and property contained in two separate homes in Oklahoma City and three different properties in Sequoyah County.
