One is an event, two is a coincidence—but three is a pattern. On Monday, the Department of Justice announced that a third Chinese national has been nabbed for allegedly trying to smuggle biological materials into the United States. Making things more disturbing is a fact that a Hollywood screenwriter couldn’t have come up with: the smuggler was studying in, where else, Wuhan, China.
You’ve heard of Wuhan, haven’t you?
The U.S. Attorney’s Office for the Eastern District of Michigan released a statement alleging that Chengxuan Han, “a citizen of the PRC” (People’s Republic of China), sent packages containing biological material related to roundworms from China to the U.S. and then lied about it.
Roundworms? Seriously?
Authorities say Han is a doctoral student at the College of Life Science and Technology in the Huazhong University of Science and Technology in Wuhan, China. According to a criminal complaint, in 2024 and 2025, Han sent four packages to the U.S. from China containing concealed biological material. The packages were addressed to persons associated with a University of Michigan laboratory.
On June 8, Han was stopped by U.S. Customs and Border Protection officers at Detroit Metropolitan Airport after arriving on a J1 visa. Officers inspected Han, who, during that time, reportedly lied to officials about the packages and the biological materials she is accused of previously sending to the U.S. Officers say Han related content from an electronic device three days before arriving in the U.S.
While being interviewed by the FBI, agents say Han admitted to sending the packages, saying the packages contained biological material related to roundworms. She also admitted to lying to officers during her inspection.
