An Irving man has been sentenced to over 13 years in federal prison for fentanyl trafficking in the Eastern District of Texas, according to U.S. Attorney Jay R. Combs.
Dulio Ariel De-La-O, a 25-year-old Irving, Texas resident, pled guilty to conspiracy to distribute and possession with intent to distribute fentanyl. US District Judge Amos L. Mazzant sentenced him to 165 months in federal prison on June 15, 2026.
According to court documents, during a 2022 drug trafficking investigation, De-La-O was caught delivering “k-packs,” or 1,000 pill quantities of fentanyl, to people in the Eastern District of Texas. A search of De-La-O’s home yielded more than 3,000 counterfeit Xanax tablets laced with fentanyl, as well as $91,799 in US currency.
The Homeland Security Task Force (HSTF), established under Executive Order 14159: Protecting the American People Against Invasion, is handling this case. The HSTF is a comprehensive government partnership dedicated to dismantling criminal cartels, international gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and around the world.
The HSTF focuses on investigating and prosecuting those involved in child trafficking or other crimes against children, and it uses all available means to prosecute and remove the most violent criminal aliens from the United States. HSTF Dallas is made up of agents and officers from various federal agencies, and Matthew T. Johnson, Assistant U.S. Attorney for the Eastern District of Texas, is leading the case.
