Del Rio Feds Nail Key Player in Massive Migrant Smuggling Ring

A Mexican national extradited from Mexico has admitted in federal court in Del Rio that he helped run a lucrative pipeline moving thousands of migrants into the United States, federal prosecutors said Monday. The guilty plea caps a multi year probe that authorities say uncovered a sprawling, international setup using stash houses in Mexico before steering people across the Rio Grande.

The U.S. Attorney's Office for the Western District of Texas flagged the plea on X in an early post by U.S. Attorney WDTX. The Department of Justice followed up with a detailed release laying out the charges and evidence behind the case.

Prosecutors Outline the Charges

According to the Department of Justice, 38 year old Efrain Zuniga Garcia pleaded guilty Monday to conspiring to bring aliens into the United States, bringing an alien for financial gain, and aiding and abetting. Prosecutors say a sentencing date has not yet been set, and Zuniga Garcia faces a mandatory minimum prison term of three years.

Court Records Show the Network's Scale and Fees

Court documents reviewed by Homeland Security Today describe a smuggling organization that moved people from Afghanistan, Yemen, Egypt, India, Pakistan, Colombia, Guatemala, Honduras and Ecuador. Prosecutors allege the group moved between 2,500 and 3,000 migrants over roughly two years and charged between $6,500 and $12,000 per person, generating what investigators estimate as tens of millions of dollars.

How Investigators Say the Operation Worked

Investigators say Zuniga Garcia ran a stash house in Monterrey and helped coordinate transports that eventually turned migrants over to armed foot guides, who then led them across the Rio Grande, according to the Department of Justice. He was arrested in Mexico in October 2024 and extradited to the United States at the request of U.S. authorities. Trial attorneys Bethany Allen of the Criminal Division’s Human Rights and Special Prosecutions Section and Assistant U.S. Attorney Joseph Duarte II for the Western District of Texas are prosecuting the case.

Legal Notes

The charges fall under 8 U.S.C. § 1324, the federal statute that criminalizes bringing in, transporting and harboring aliens and increases penalties when the conduct is for commercial advantage. In certain cases involving financial gain, that law requires a mandatory minimum prison term of three years, as outlined on the Cornell Law School site.

Why This Matters

Prosecutors say the plea is part of an ongoing enforcement surge driven by Joint Task Force Alpha and the Justice Department's Operation Take Back America. Those efforts have been credited with hundreds of arrests and dozens of convictions, according to Homeland Security Today. The case will return to the federal courthouse in Del Rio for a future sentencing hearing.
