Submariner Smugglers Extradited from Colombia to Face International Cocaine Distribution Charges

This afternoon, in federal court in Brooklyn, Elkin Armando Alomia Quiñones, Luis Alberto Arboleda Escobar, Diego Luis Obregon Aguirre, Edwin Obregon Castro, Juan Matias Obregon Castro, Rodrigo Obregon Saavedra and Narjel Paredes, all citizens of Colombia, will be arraigned before United States Magistrate Judge James R. Cho on an indictment charging them with violations of the Maritime Drug Law Enforcement Act and international cocaine distribution conspiracy. The seven defendants were extradited yesterday to the Eastern District of New York from Colombia where they were previously arrested in March 2025.

Joseph Nocella, Jr., United States Attorney for the Eastern District of New York, Frank A. Tarentino III, Associate Chief of Operations, U.S. Drug Enforcement Administration (DEA), Northeast Region, and Michael Alfonso, Acting Special Agent in Charge, Homeland Security Investigations, New York (HSI New York) announced the extraditions.

"As alleged, the defendants are members of a Colombian transnational maritime drug trafficking organization who sought to clandestinely traffic tons of cocaine on semi-submersible vessels to Mexico, ultimately for distribution in the United States," stated United States Attorney Nocella. "With these arrests and extraditions, the defendants' smuggling scheme has been sunk and holding them accountable in a U.S. courtroom demonstrates the Administration's resolve through Operation Take Back America and the Homeland Security Task Force to eliminate cartels and transnational criminal organizations and protect our communities from these evildoers."

Mr. Nocella praised the outstanding investigative work of DEA New York's Task Force, DEA Bogota and HSI New York's Homeland Security Task Force Cartel Investigations Group. Mr. Nocella also expressed his appreciation to Colombia's Cuerpo Técnico de Investigación, the Colombian Navy, DEA Puerto Rico, DEA Madrid, HSI Bogota and the U.S. Attorney's Office for the District of Puerto Rico for their substantial assistance. The Justice Department's Office of International Affairs and the Criminal Division's Office of the Judicial Attaché in Bogotá provided significant assistance in this matter.

"The extradition of these seven individuals underscores DEA's global pursuit to identify and target those responsible for trafficking illicit narcotics destined for the United States," stated DEA Northeast Regional Associate Chief of Operations Tarentino. "Using submersible vessels in a calculated attempt to evade law enforcement doesn't make you invisible! Whether you attempt to hide beneath the surface or above, the DEA, alongside our domestic and international partners, will relentlessly pursue and defeat those drug trafficking organizations threatening our communities and killing Americans."

"Today, seven alleged drug smugglers are facing charges in the United Stated after years of unchecked cocaine trafficking.​ Homeland Security Investigations' international footprint gives us the ability to track bad actors back to the source and, through our partnerships, bring them to justice," stated HSI New York Acting Special Agent in Charge Alfonso. "These drugs have done untold damage to millions of families across the country. HSI works alongside our law enforcement partners every day to dismantle drug trafficking organizations and stop the flow of dangerous drugs into our communities."

According to the indictment and court filings, the defendants were members of an international drug trafficking organization (DTO) which conspired to traffic more than five tons of cocaine in self-propelled semi-submersible vessels, like submarines, launched from the Pacific coast of Colombia towards areas controlled by the Sinaloa Cartel in Mexico. The drug trafficking organization conducted a sophisticated maritime drug distribution operation, managing each step of the process. First, members of the conspiracy found investors to finance multi-ton cocaine loads and to finance the construction of semi-submersible vessels. Next, members of the conspiracy built semi-submersible vessels capable of carrying thousands of kilograms of cocaine. The trafficking organization also hired crew members to fill the semi-submersible vessels with cocaine and then transport the cocaine to Mexico. Members of the conspiracy also conducted countersurveillance on the high seas by strategically positioning fishing vessels on the same routes as the semi-submersible vessels. These countersurveillance ships attempted to spot military and law enforcement ships that might intercept the semi-submersible vessels.

On June 27 2023, the Colombian Navy seized approximately 2,312 kilograms of cocaine from a DTO semi-submersible vessel near the Colombian Pacific coast, which, based on a coordinate chart located aboard the vessel, was en route to Mexico (pictured below).

On October 7, 2023, the Colombian Navy seized approximately 3,300 kilograms of cocaine from another DTO semi-submersible vessel near the Colombian Pacific coast, which was en route to Mexico (pictured below).

The charges in the indictment are allegations and the defendants are presumed innocent unless and until proven guilty.

This prosecution is part of the Homeland Security Task Force initiative established by Executive Order 14159, Protecting the American People Against Invasion.
