El Paso Federal Court Sentences Man for Role in Sophisticated Cross-Border Tunnel Smuggling Operation

A federal court in El Paso has sentenced a Mexican national to 42 months in prison for his central role in a human smuggling operation that utilized a complex network of cross-border tunnels and storm drains. The sentencing follows a significant investigation into the subterranean methods used to bypass border security and move individuals illegally into the United States.

According to the U.S. Attorney’s Office for the Western District of Texas, Ricardo Guadalupe Dominguez, 54, of Ciudad Juárez, Chihuahua, was sentenced for facilitating smuggling activities through the use of man-made passages and existing drainage infrastructure.

A Sophisticated Subterranean Scheme

The investigation revealed a highly organized method of transport designed to evade detection by border authorities. Dominguez did not merely participate in the movement of people; he provided the essential logistics required to maintain the network. Court documents indicate that he supplied vehicles and tools used to tamper with and damage existing storm drains to facilitate the smuggling process.

The scale of the operation was highlighted by the discovery of a man-made cross-border tunnel on January 10, 2025. Authorities identified Dominguez as being involved in the construction of this clandestine passage.

One of the most brazen tactics used by the organization involved a specialized vehicle. To move people from the underground tunnels to the surface, the group used a box truck modified with a trap door. This truck would be driven directly over a manhole cover at the tunnel’s exit. Once positioned, the trap door was opened, allowing individuals to climb directly from the tunnel into the truck, effectively remaining invisible to surface-level surveillance.

Legal Outcomes and Sentencing

Dominguez’s legal proceedings concluded after he was arrested while attempting to enter the United States from Mexico at the Paso Del Norte Port of Entry. He pleaded guilty to one count of conspiracy to bring in aliens on December 17, 2025. The sentencing was announced by U.S. Attorney Justin R. Simmons.

The crackdown on this smuggling ring also resulted in the conviction of co-defendant Oscar Ivan Carrillo. In January, Carrillo was sentenced to 33 months in federal prison for conspiracy to use a border tunnel. Authorities noted that Carrillo and other members of the network were responsible for guiding migrants through the tunnels to ensure they reached U.S. Territory.

The case was the result of a coordinated effort by Homeland Security Investigations (HSI), which operates under ICE, and the U.S. Border Patrol.
