Three Port of San Juan Employees Arrested for Narcotics Violations

For Immediate Release
U.S. Attorney's Office, District of Puerto Rico

SAN JUAN, Puerto Rico – A federal grand jury in the District of Puerto Rico returned an indictment charging Carlos Alberto Hernández-Laguer, a/k/a “Brea”, Luis Roberto De León-Sánchez, a/k/a “Coco”, and Misael Ruiz-Valentín, a/k/a “Misa”, with four counts of conspiracy to import cocaine, importation of cocaine, conspiracy to possess with intent to distribute cocaine, and possession with intent to distribute cocaine.

On November 6, 2023, Homeland Security Investigations (HSI) San Juan, Seaport-Border Enforcement Security Taskforce (BEST) and partner agencies, arrested three longshoremen working at the Port of San Juan for their involvement in facilitating the transportation of narcotics between the Dominican Republic, Puerto Rico, and the Continental United States.

According to court documents, on or about June 7, 2022, the defendants intentionally conspired and agreed to possess, import, and distribute cocaine into the United States from the Dominican Republic. The HSI San Juan Seaport-BEST investigation revealed that the three Port of San Juan longshoremen were members of a Transnational Criminal Organization (TCO) operating between the Dominican Republic and Puerto Rico. These longshoremen exploited their positions to circumvent security and smuggle large quantities of cocaine concealed in cargo ship containers and compartments/voids within the cargo ships.

“Disrupting drug trafficking networks is vitally important to our ongoing efforts to combat the drug trafficking in Puerto Rico and the violence associated with drug trafficking,” said W. Stephen Muldrow, United States Attorney for the District of Puerto Rico. “International cartels like these affect many jurisdictions and stopping them requires robust coordination with our domestic and international partners.”

HSI San Juan Special Agent in Charge, Rebecca González-Ramos said: “Our agents are relentless in their efforts to protect our borders by dismantling any criminal scheme that facilitates the entrance of poisonous narcotics into our island.  This multi-agency law enforcement collaboration is a great example of the work we are doing to detect any intent to smuggle deadly contraband into our communities. With these arrests, HSI is sending a clear and strong message: nobody is above the law, we will find those who violate the law and hold them accountable for their decisions -- especially those in critical positions in our ports that create vulnerabilities to our island.”

If convicted, the defendants face a mandatory minimum penalty of 10 years in jail and a maximum penalty of life imprisonment. A federal district court judge will determine any sentence after considering the U.S. Sentencing Guidelines and other statutory factors.

This significant operation was successful with the support of U.S Customs and Border Protection (CBP) Office of Field Operations San Juan, the Drug Enforcement Administration, the Coast Guard Investigative Services and CBP Air and Marine Operations.

Assistant United States Attorney (AUSA) Max Pérez-Bouret, Chief of the Transnational Organized Crime Section, AUSA María L. Montañez-Concepción, Deputy Chief of the Transnational Organized Crime Section, and AUSA Camille García-Jiménez are prosecuting the case.
