United States Drug Enforcement Administration

MIAMI – A Chinese national and a Las Vegas man have been charged by federal indictment for their roles in a scheme to import large quantities of the powerful synthetic opioid protonitazene in the U.S. and distribute it as counterfeit pills. These charges stem from an investigation by the U.S. Drug Enforcement Administration (DEA) and the U.S. Postal Inspection Service (USPIS), with assistance and collaboration with the People’s Republic of China’s Ministry of Public Security.

According to court records, beginning in approximately September 2024, Jia Guo, a/k/a “idmaster21,” a/k/a “imyourBDOguy,” a/k/a “OXY GUY,” of China, and Seven Schmidt, a/k/a “Vegas,” of Nevada, operated a drug trafficking organization that sourced protonitazene overseas and shipped it into the U.S. for distribution. Protonitazene — often used in counterfeit pill production — is significantly more potent than fentanyl. A quantity as small as 200 grams can produce hundreds of thousands of pills, each potentially lethal.

“This case shows why President Trump’s Homeland Security Task Force matters,” said U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida. “The indictment alleges that a China-based supplier and a domestic distributor worked together to bring a deadly synthetic opioid into the United States and turn it into counterfeit pills for distribution across the country. These pills are made to look familiar, but one pill can kill. If you use South Florida as a gateway to import synthetic opioids, make counterfeit pills, or profit from addiction, you will face federal prosecution. The charges are allegations, and the defendants are presumed innocent unless and until proven guilty.”

“The bilateral investigation with the Chinese Ministry of Public Security underscores DEA Asia Pacific Division’s unwavering commitment to the protection of American lives: disrupting criminal organizations responsible for distributing dangerous synthetic opioids across the United States is one of DEA’s main priorities,” said Special Agent in Charge David L. King of the DEA Asia Pacific Division. “We commend the Chinese Ministry of Public Security for their thorough and swift investigative work on this case, which was initially presented at the February 2026 Bilateral Drug Enforcement Intelligence Working Group, hosted by DEA Asia Pacific Division in Colorado.”

“This was the very definition of agents and officers working in unison to bring these criminals to justice,” said Special Agent in Charge Miles Aley of the DEA Miami Field Division. “Lives will be saved because of their efforts.”

“The US Postal Inspection service remains committed to removing these poisons from our communities,” said Inspector in Charge Bladismir Rojo of the USPIS, Miami Division. “These charges serve as a warning to others that, using the US Mail to distribute dangerous drugs has consequences.” 

Guo allegedly coordinated the illegal procurement and shipment of protonitazene from China to co-conspirators, including an associate in Miami-Dade County. That associate allegedly used pill presses to manufacture counterfeit pills, which were then distributed to drug dealers throughout the U.S. 

Schmidt allegedly ordered distribution quantities of the counterfeit pills and arranged for their shipment from South Florida to Nevada using the U.S. Postal Service.

As part of the investigation, China’s Ministry of Public Security took law enforcement action in China against Guo. In April 2026, Chinese officials arrested Guo and the freight forwarder, who Guo conspired with to send controlled substance parcels to the U.S. As part of the investigation, the Ministry of Public Security seized 10 parcels filled with controlled substances that Guo sent which were for recipients in the U.S. The Justice Department thanks the Ministry of Public Security for its assistance and coordinated efforts.

Guo and Schmidt are charged with conspiracy to import protonitazene into the United States from China and conspiracy to possess with intent to distribute protonitazene. If convicted, each defendant faces a maximum penalty of 20 years in prison for each of the two counts.

U.S. Attorney Reding Quiñones, Special Agent in Charge Aley, Special Agent in Charge King, and Inspector in Charge Rojo made the announcement.

DEA Miami, USPIS Miami, and DEA Beijing are investigating the case with the assistance from and in collaboration with China’s Ministry of Public Security. U.S. Customs and Border Protection, the Homestead (FL) Police Department, the Henderson (NV) Police Department, DEA Dallas, DEA Las Vegas, DEA Seattle, the Miami-Dade Sherriff’s Office, and the Miami Beach Police Department also provided invaluable assistance.

Assistant U.S. Attorney Monique Botero is prosecuting the case. Assistant U.S. Attorney Mitchell Hyman is handling asset forfeiture. The U.S. Department of Justice’s Office of Prosecutorial, Development, Assistance and Training (OPDAT) Beijing Resident Legal Advisor, U.S. Attorney’s Office for the District of Nevada, and the U.S. Department of Justice’s Office of International Affairs provided significant assistance in this matter.

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 United States 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 Miami comprises of agents and officers from DEA and USPIS with the prosecution being led by the United States Attorney’s Office for the Southern District of Florida.

An indictment is merely an allegation. All defendants are presumed innocent until proven guilty beyond a reasonable doubt in a court of law.
