DALLAS, TX — Special Agent in Charge Joseph B. Tucker and the United States Attorney for the Northern District of Texas Ryan Raybould announced that a Dallas man who admitted to running a multi‑state marijuana distribution operation was sentenced today in federal court for conspiracy to use interstate facilities in aid of racketeering. 

U.S. District Judge Sam A. Lindsay sentenced Dian Huang Jiang, aka “Danny Jiang,” to 60 months in federal prison.

“This case sends a clear message; drug traffickers do not get a free pass simply because marijuana laws vary from state to state” said DEA Dallas Special Agent in Charge Joseph B. Tucker. “Mr. Jiang moved large quantities of marijuana across state lines and supplied dangerous criminals who fuel violence and threaten our communities.  We will continue to work with our law enforcement partners to dismantle networks and prevent drug proceeds from strengthening criminal organizations.”

“Drug traffickers who exploit interstate networks to pump poison into our communities will be met with the full force of federal prosecution,” said U.S. Attorney Ryan Raybould. “Mr. Jiang built a sprawling, multi‑state drug enterprise that pushed thousands of kilograms of marijuana and funneled millions of dollars in proceeds through criminal channels. The Homeland Security Task Force unraveled that operation piece by piece, and today’s sentence reflects our unwavering commitment to dismantling criminal organizations that threaten public safety.”

According to court documents, Jiang pleaded guilty to conspiracy to use interstate facilities in aid of racketeering. From at least January 2020 through August 2023, Jiang led a large‑scale distribution network responsible for moving marijuana from Oklahoma to customers across Texas and multiple other states. Jiang routinely used cellular telephones to coordinate marijuana deliveries, negotiate pricing and direct customers where to drop off large quantities of U.S. currency as payment for drug shipments. 

Court records show Jiang acquired multi‑ton quantities of marijuana, often distributing up to 1,000 pounds in a single day, and required customers to purchase between 20 and 300 pounds per transaction. He utilized multiple residences in Oklahoma and Texas to store, distribute and collect proceeds from the illegal drug enterprise. As part of the conspiracy, Jiang and his coconspirators transported drug proceeds between states, sometimes sending substantial amounts overseas to include the People’s Republic of China. On Aug. 8, 2023, federal agents seized more than $2.8 million from bank accounts and safe deposit boxes linked to Jiang’s operation. 

In addition to the prison term, Jiang faces forfeiture of several residential properties used in the drug‑trafficking operation as well as more than $4 million in drug proceeds traced by investigators.

The Drug Enforcement Administration Dallas Field Division conducted the investigation with assistance from the Federal Bureau of Investigation (Oklahoma City), the Bureau of Narcotics and Dangerous Drugs, Oklahoma and the City of Mesquite Police Department. Assistant U.S. Attorneys Joseph T. Lo Galbo and Rick Calvert prosecuted the case with assistance from Assistant U.S. Attorneys Phelesa Guy and Jonathan Penn. 

This prosecution is part of the Homeland Security Task Force (HSTF) initiative established by Executive Order 14159, Protecting the American People Against Invasion. The HSTF is a whole-of-government partnership dedicated to eliminating criminal cartels, foreign gangs, transnational criminal organizations, and human smuggling and trafficking rings operating in the United States and abroad. Through historic interagency collaboration, the HSTF directs the full might of U.S. law enforcement towards identifying, investigating, and prosecuting the full spectrum of crimes committed by these organizations, which have long fueled violence and instability within our borders. In performing this work, the HSTF places special emphasis on investigating and prosecuting those engaged in child trafficking or other crimes involving children. The HSTF further utilizes all available tools to prosecute and remove the most violent criminal aliens from the United States. HSTF Dallas comprises agents and officers from the Federal Bureau of Investigation, the Drug Enforcement Administration, the Bureau of Alcohol, Firearms, Tobacco, and Explosives, Department of Homeland Security Investigations, United States Marshals Service, Internal Revenue Service, United States Postal Inspection Service, and United States Secret Service in partnership with the Texas Department of Public Safety, City of Dallas Police Department, the Dallas County Sheriff’s Office and other local law enforcement entities. The prosecution was led by the United States Attorney’s Office for the Northern District of Texas.
