Chinese Government Intervention Leads to Dismissal of Worm Smuggling Charges
Defense attorneys have disclosed that China's government intervened to secure the dismissal of criminal charges against three Chinese scientists at the University of Michigan. The researchers were accused of assisting a colleague in smuggling biological materials into the United States, which were later identified as mostly harmless, transparent worms.
National Security Claims Versus Harmless Organisms
Last year, U.S. officials celebrated the arrests as a significant victory for national security. Attorney General Pam Bondi emphasized the necessity for vigilance when foreign nationals attempt to "advance a malicious agenda." However, the materials involved were determined to be non-dangerous, tiny worms commonly used in scientific studies of chemical reactions and light sensitivity.
The accused individuals, Xu Bai and Fengfan Zhang, faced charges of conspiracy for allegedly helping another scientist ship packages from China before her arrival in 2025 for temporary laboratory research at the University of Michigan. A third defendant, Zhiyong Zhang, was charged with making false statements to authorities. All three spent over three months in jail while the case proceeded in federal court in Detroit.
Sudden Dismissal and Diplomatic Negotiations
On February 5, a judge abruptly dismissed the charges at the request of the Justice Department, allowing the three scientists to return home to China. The U.S. Attorney's Office in Detroit declined to comment on China's role or the reasons behind the government's retreat. An email seeking comment from the Chinese Consulate in Chicago was not immediately answered.
Defense lawyer John Minock expressed surprise at the dismissal, stating, "The dismissal came as a pleasant surprise. We don’t know the details. What we were told was there was some kind of intervention by the Chinese Consulate in Chicago."
Another attorney, Ray Cassar, revealed that lawyers were negotiating a misdemeanor plea deal when prosecutors unexpectedly dropped the case. Cassar explained, "We get this phone call saying China is negotiating with the U.S. over these three students. Serious talks. These were kids studying for their Ph.D.s. The last thing you want to do is destroy their careers. ... Was it the proper thing to do? Absolutely."
Context of the Smuggling and Related Cases
Bai, Zhang, and Zhang were research scholars admitted to the U.S. for temporary work at the University of Michigan. Cassar noted that the worms had a limited lifespan and the packages were improperly labeled because the sender, Chengxuan Han, likely wanted to avoid delays by U.S. inspectors. He asserted, "There was no intention of doing anything nefarious."
In a related development, Han pleaded no contest to smuggling and making false statements in September and was deported to China after three months in jail. In a separate case, Yunqing Jian, another temporary researcher, pleaded guilty to similar charges involving a common plant fungus and was deported after five months in custody.
Roger Innes, an Indiana University expert who reviewed evidence for Jian's attorneys, confirmed there was no risk to anyone in the U.S. from the materials involved.
