Eastern District of Texas prosecutes multiple defendants as part of Homeland Security Task Force investigations in August 2026
Three defendants sentenced to 386 months, another faces life in federal prison as U.S. Attorney’s Office advances DOJ mission to protect the Homeland
PLANO, Texas – The Homeland Security Task Force (HSTF) initiative was established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of United States law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States.
In the Eastern District of Texas, three defendants were sentenced to a total of 386 months in federal prison during the month of August as part of the Homeland Security Task Force, announced U.S. Attorney Jay R. Combs. Additionally, another defendant was convicted by a jury of drug trafficking violations and faces life in federal prison at sentencing.
On August 6, 2026, Jose Romero-Sanchez, 25, a Mexican national illegally living in Dallas, was sentenced to 156 months in federal prison for receiving multi-kilo quantities of methamphetamine from Mexico and storing them at his residence for further distribution.
On August 25, 2026, a Dallas man was sentenced to 200 months in federal prison for drug trafficking violations in the Eastern District of Texas. Joshua Isaiah Castillo, 31, is responsible for trafficking large amounts of fentanyl-laced counterfeit pills and fentanyl powder in bulk form for redistribution.
On August 27, 2026, Jose Guadalupe Lopez-Arana, 41, a Mexican national illegally living in Irving, was sentenced to 30 months in federal prison for laundering between $150,000 and $250,000 in drug proceeds.
On August 27, 2026, 45-year-old Colombian, Nelson Javier Christancho Parada, was found guilty by a jury of two counts of federal drug trafficking violations. Christancho Parada used his skills as a machinist to manufacture water bag rolls with a false compartment in them. He and others filled the false void with kilograms of cocaine that were intended to be sent to the United States. The Colombia National Police, Homeland Security Investigations, and DEA were able to seize 1,207 kilograms of cocaine on November 22, 2019, on the island of San Andres, Colombia, that were sent in a cargo shipment. The cocaine was found in hidden voids in the containers that Christancho Parada manufactured. He faces life in federal prison at sentencing.
“Christancho Parada’s verdict marks another significant step in our ongoing efforts to dismantle the transnational criminal networks that threaten the safety and security of our communities,” said U.S. Attorney Jay R. Combs. “This defendant exploited his technical skills to hide more than a metric ton of cocaine destined for the United States, but through the dedication of our Colombian partners and the unwavering commitment of Homeland Security Task Force agencies, his scheme was uncovered and justice has been served. The Homeland Security Task Force represents a historic level of coordination among federal law enforcement, and this case demonstrates exactly why that partnership matters. We will continue to use every lawful tool at our disposal to identify, investigate, and prosecute those who traffic drugs, exploit vulnerable people, and endanger Americans. I am grateful for the outstanding work of our agents, officers, and prosecutors whose efforts made this outcome possible.”
