Guatemalan National Pleads Guilty in Major U.S. Cocaine Importation Conspiracy

Donelfert Monterroso Vasquez, a 51-year-old Guatemalan national, has pleaded guilty to conspiring to import over 450 kilograms of cocaine into the United States. His plea was announced by the U.S. Department of Justice, highlighting a significant step in a major international drug trafficking case.

According to court documents, Monterroso Vasquez orchestrated the movement of large quantities of cocaine from Colombia, through Guatemala, and into Mexico. From there, a network of associates transported the drugs into the United States, where they were intended for distribution. Monterroso Vasquez and his co-conspirators used an encrypted communication platform to coordinate their activities. In one instance, Monterroso Vasquez sent an image of a cocaine brick stamped with "USA," indicating its intended destination.

Monterroso Vasquez was arrested upon landing at a U. S. airport in June 2026 and has remained in custody since his arrest.

He is scheduled to be sentenced on January 26, 2027, facing a mandatory minimum sentence of 10 years and a maximum of life in prison. The final sentence will be determined by a federal district court judge, who will consider the U. S.

Sentencing Guidelines and other statutory factors.

The case was investigated by the Drug Enforcement Administration (DEA) Memphis, with assistance from the DEA's Special Operations Division, its offices in Guatemala and Colombia, and the Guatemalan National Police. The announcement of the guilty plea was made by Assistant Attorney General A. Tysen Duva of the Justice Department’s Criminal Division, U.

S. Attorney Theophani K. Stamos for the Eastern District of Virginia, and Special Agent in Charge Jim Scott of the DEA's Louisville Field Division.

The prosecution team includes Trial Attorney Claire Galasso of the Criminal Division’s Money Laundering, Narcotics and Forfeiture Section (MNF), along with Assistant U. S. Attorneys Edgardo J.

Rodriguez and Christopher M. Carter for the Eastern District of Virginia. The MNF is tasked with dismantling drug cartels and protecting the U.

S. financial system by pursuing criminal prosecutions and asset recovery actions.

This case underscores the international collaboration required to combat drug trafficking and highlights the ongoing efforts of U.S. authorities to intercept and dismantle drug smuggling operations that threaten national security and public health.
