Six suspected drug traffickers, accused of utilizing “narco subs” and aircraft to move large quantities of cocaine, were hit with U.S. sanctions earlier this week, as reported by the U.S. Department of the Treasury’s Office of Foreign Assets Control.
Two Colombians, Manuel Salazar Gutierrez and Yeison Andres Sanchez Vallejo, along with four Guyanese nationals, Randolph Duncan, Himnauth Sawh, Mark Cromwell, and Paul Daby Jr., have been sanctioned for allegedly trafficking tons of cocaine from South America to the United States, Europe, and the Caribbean, officials stated.
“Under President [Donald] Trump, this administration has achieved the most secure border in modern history,” Deputy Secretary Michael Faulkender mentioned in a statement. “The Treasury Department continues to employ our unique tools and authorities in the battle against cartels and their affiliates.”

In March 2025, a cargo vessel from Guyana was discovered by authorities off the coast of Trinidad and Tobago carrying approximately 400 pounds of cocaine, the Treasury said. The packages were stamped with the Toyota logo, known to be used by the Sinaloa Cartel.
Last year, U.S. and Guyanese law enforcement seized approximately 5,200 pounds of cocaine from a self-propelled narco sub operating off the coast of Guyana.

The Treasury Department did not immediately respond to Fox News Digital’s request for comment.
“Treasury will continue to expose the criminal networks that allow for drugs to be trafficked into the United States,” Faulkender said. “[We will] work closely with our law enforcement colleagues and the Government of Guyana to disrupt the cartels wherever they operate.”
