Two Chinese nationals were arrested in China after U.S. prosecutors accused them of supplying synthetic drugs later distributed to inmates in federal and state prisons across the United States. The alleged operation involved dissolving synthetic opioids, cannabinoids and other drugs into liquid, soaking paper in the mixture and mailing it to incarcerated recipients. The case also includes allegations of money laundering and a China-based supply network connected to domestic distributors.
The superseding indictment was filed in the Eastern District of Texas. Chinese authorities also arrested 19 additional alleged co-conspirators, seized 475 kilograms of synthetic cannabinoids and shut down four illicit manufacturing sites, according to the Justice Department.
U.S. and Chinese authorities said the investigation was coordinated through an FBI and Chinese Ministry of Public Security counternarcotics working group established earlier in 2026. If convicted, each defendant faces a mandatory minimum sentence of 10 years in prison and a maximum sentence of life imprisonment.

Charges and alleged roles in the supply network
Lisa Xing, 36, and Zhanwen Song, 38, were named in a superseding federal indictment in the Eastern District of Texas. Prosecutors accuse them of drug trafficking and money laundering offenses connected to an alleged scheme in which synthetic drugs were supplied from China for distribution in U.S. correctional facilities.
The case also names Adell Willis of Texas and Judy Ly of Michigan. They were indicted in May on charges that included conspiracy to distribute controlled substances and conspiracy to commit money laundering. The allegations describe a division of responsibilities between overseas suppliers and domestic distributors.
How drugs were allegedly sent into prisons
According to prosecutors, Xing and Song allegedly shipped synthetic drugs to Willis and Ly in the United States. The domestic defendants are accused of dissolving the substances into a liquid and soaking sheets of paper in the mixture.
The paper was then allegedly mailed to inmates in federal and state prisons across the country. Investigators say this method allowed synthetic opioids, cannabinoids and other drugs to be introduced into correctional facilities through ordinary-looking mail. The allegations remain unproven unless established in court.
International arrests and seized evidence
Chinese authorities arrested Xing, Song and 19 additional alleged co-conspirators in China. The Justice Department said the operation also resulted in the seizure of 475 kilograms of synthetic cannabinoids and the closure of four illicit manufacturing sites.
The arrests and seizures represent the international dimension of the investigation. U.S. prosecutors allege that the China-based supply activity was linked to the later distribution of drugs inside American prisons, while the reported manufacturing-site closures targeted production capacity connected to the broader network.
Cross-border investigation and law enforcement response
The investigation was coordinated through a counternarcotics working group involving the FBI and China’s Ministry of Public Security. Officials said the group was established earlier in 2026 to support cooperation on drug trafficking investigations between the two countries.
U.S. Attorney Jay R. Combs said the indictment alleges that a China-based supplier and a domestic distributor worked together to bring synthetic drugs into the United States for nationwide distribution. FBI Director Kash Patel said investigators and Homeland Security Task Force partners would continue targeting the networks involved.
“The indictment alleges that a China-based supplier and a domestic distributor worked together to bring deadly synthetic drugs into the United States for distribution across the country.”
Potential penalties and next legal steps
Each defendant faces a mandatory minimum sentence of 10 years in prison if convicted. The maximum penalty is life imprisonment. The charges will proceed through the federal court system, where prosecutors must prove the allegations beyond a reasonable doubt.
The indictment does not itself establish guilt. The defendants retain the right to contest the charges, challenge the evidence and receive a trial or pursue other legal proceedings permitted under federal law.
| Number | Key Point |
|---|---|
| 1 | Two Chinese nationals face U.S. charges tied to alleged synthetic drug trafficking and money laundering. |
| 2 | Prosecutors allege drugs were dissolved, transferred onto paper and mailed to prison inmates. |
| 3 | Chinese authorities reported 21 arrests in total, including 19 additional alleged co-conspirators. |
| 4 | Authorities seized 475 kilograms of synthetic cannabinoids and closed four alleged manufacturing sites. |
Summary
The case alleges a cross-border supply chain that moved synthetic drugs from China to domestic distributors and ultimately into U.S. correctional facilities. The reported arrests, seizures and manufacturing-site closures reflect coordinated action by U.S. and Chinese authorities, while the defendants’ guilt will be determined through the federal court process.
