A 28-year-old man living illegally in Cleveland will spend more than 16 years behind bars after federal investigators say he ran a cocaine pipeline that stretched from Mexican cartels into the heart of Texas — and sent guns back across the border to arm the same cartels supplying him.
U.S. District Judge David S. Morales sentenced Elmer Vargas-Serrato, a Mexican national, to 201 months in federal prison. He pleaded guilty in October 2025 to conspiracy to distribute 5 kilograms or more of cocaine.
Investigators say Vargas-Serrato led a trafficking organization that moved cocaine from cartels in Mexico into Houston and Dallas, then distributed it further to cities in Illinois, New York, Georgia and North Carolina. He was the one sourcing the cocaine and directing the group’s operations across the U.S., authorities said. The organization is also accused of running firearms back into Mexico to arm the cartels.
Authorities tied Vargas-Serrato to roughly 41 kilograms of cocaine seized across three states. A search warrant carried out at a residence connected to him turned up cocaine, a stolen firearm, and drug ledgers detailing the movement of narcotics and weapons. Investigators also recovered titles to multiple vehicles believed to have been used to transport the drugs.
Because he is not a U.S. citizen, Vargas-Serrato is expected to face removal proceedings once his prison sentence is served. He remains in custody awaiting transfer to a federal facility.
The case was investigated under the Homeland Security Task Force initiative, a multi-agency effort targeting cartels, foreign gangs and human smuggling operations. Agencies involved included Homeland Security Investigations, the FBI, the DEA, ATF, U.S. Marshals Service, U.S. Postal Inspection Service, IRS Criminal Investigation and the Naval Criminal Investigative Service.
The case was prosecuted out of the Southern District of Texas.
