Puerto Rican Man Sentenced in Waco for Role in Fentanyl Death of Army Spouse

WACO, Texas - A Puerto Rican man was sentenced in a federal court in Waco today to 188 months in prison for his role in a fentanyl trafficking conspiracy to possess that resulted in the death of a U.S. Army spouse, announced U.S. Attorney for the Western District of Texas, Justin R. Simmons.

According to court documents, Gilberto Joel Hernandez-Marin, 31, of Trujillo Alto, Puerto Rico, led a Puerto Rico-based drug trafficking organization with co-conspirator Adxel Romero-Flores, 34, of Bayamon, Puerto Rico. The DTO was found to be directly responsible for the distribution of fentanyl that resulted in the death of a dependent spouse of an active-duty U.S. Army soldier along with the distribution of thousands of fentanyl pills throughout the Western District of Texas.

During the investigation, the Department of the Army Criminal Investigation Division intercepted approximately 8,100 deadly fentanyl pills from the DTO that were destined for central Texas.

"Hernandez-Marin and his co-conspirators in this Puerto Rican DTO knowingly and recklessly trafficked thousands upon thousands of deadly fentanyl pills into our communities, ultimately killing a U.S. military spouse," said U.S. Attorney Simmons. "Thanks to the investigative actions of our partners at Army CID, we were able to put a stop to this group's deadly fentanyl trafficking and hold them accountable."

Hernandez-Marin, Romero-Flores, and codefendants Julio Samuel Bonilla-Tirado, 44, of Copperas Cove, Juan Carlos Cabral, 34, of Bayamon, Puerto Rico, each pleaded guilty and were sentenced at various stages throughout the case. U.S. District Judge Alan Albright sentenced Bonilla-Tirado to 14 years in prison on July 9, 2025. Romero-Flores was sentenced to 15 years and eight months in prison on Dec. 2, 2025; and Cabral was sentenced to 20 years in prison on March 31.

"These sentencings are the result of outstanding teamwork and dedication from our Special Agents and our local, state, and federal law enforcement partners," said Special Agent in Charge Lane Allen, Army CID Central Texas Field Office. "This case underscores our commitment to combatting threats of illegal drugs affecting the Army community, regardless of their origins."

Army CID investigated the case with valuable assistance provided by the Drug Enforcement Administration; ICE Homeland Security Investigations; the U.S. Postal Inspection Service; the U.S. Marshals Service; the Texas Department of Public Safety Criminal Investigation; the Killeen Police Department; the Copperas Cove Police Department; and the Puerto Rico Police Department.

Assistant U.S. Attorney Christopher Blanton prosecuted the cases.
