Surveillance footage, eBay purchases, and a shared office coffee maker point to acrylamide poisoning of a Vietnamese researcher with pending patents; the case echoes the unsolved 1990s thallium attack on a Tsinghua University student.
A 32-year-old Chinese microbiology graduate student at the University of Wyoming was arrested at Los Angeles International Airport on October 6 while allegedly attempting to board a flight back to China, one day after campus police interviewed her about the poisoning of a colleague’s tea.
Aili Wang faces a felony aggravated assault and battery charge in Albany County Circuit Court. The charge carries up to 10 years in prison and a $10,000 fine. Prosecutors say she bought acrylamide—a neurotoxic chemical used in some laboratory work—on eBay on two occasions last summer, then placed it in the water of a small coffee maker that her office-mate used to brew tea. The victim, identified in court papers only as K.T., is a Vietnamese graduate student whose patent-pending research involves delivering RNA to human cells via bacteria for potential treatments of cancer, neurological, and genetic diseases. The two students shared an office in the university’s agricultural building but did not get along, according to a University of Wyoming Police Department affidavit.
Symptoms, Surveillance, and a White Powder
K.T. began reporting extreme fatigue, insomnia, fingertip numbness and tingling, leg weakness, and later loss of sensation in his left hand after a conference in August. He also noticed a strange taste in tea made with the desk coffee maker. His wife and others evaporated water from the machine and isolated 63 milligrams of white powder that tested positive for acrylamide. Samples from other water sources in the building tested negative.
Campus police and the victim installed surveillance cameras in the shared space. Video from September 27 shows Wang going through K.T.’s desk. Footage from October 1 shows her photographing and handling his notebooks and rinsing his mug with liquid from her own mug. On October 5, when campus police interviewed her, Wang said she “had not used acrylamide in years.” The same day she contacted eBay asking to delete her account and order history. She left Laramie and was arrested the next day at LAX in possession of multiple laptops, external storage devices, physical records, and written materials, all now held by police.
Albany County Circuit Court Judge Robert Sanford raised her bond from the initial $200,000 to $1.5 million cash-only upon extradition. Wang remained jailed without bail in Los Angeles as of mid-October. There is no bilateral extradition treaty between the United States and China.
Envy, Patents, and the Broader Pattern
Molecular biology professor Mark Gomelsky, who supervised both students, told the Associated Press the accusations left him reeling. “It’s been disheartening, to say the least, to see that one of your student’s life is in jeopardy and another student may be responsible for that. That was one of the worst shocks in my professional career.” He noted that Wang had failed her first dissertation defense and appeared envious of K.T.’s progress. Gomelsky described acrylamide as a neurotoxin that “cannot be neutralized so it stays in neurons and basically kills them,” adding that it is unclear whether the victim will fully recover. Chemistry assistant professor Takashi Suyama, who helped analyze the powder, observed that the quantity was suspicious and that there was no legitimate reason for Wang to photograph every page of a lab-mate’s notebook.
U.S. officials have for years documented systematic Chinese efforts to obtain American university research, including through graduate students. The affidavit notes that Wang had worked on similar research in China before arriving in the United States.
An Earlier Parallel: The Zhu Ling Case at Tsinghua
The Wyoming allegations recall the still-unsolved 1994–1995 thallium poisoning of Zhu Ling, a talented chemistry student and musician at Tsinghua University in Beijing. Zhu was poisoned at least twice with the heavy metal; after months of misdiagnosis she fell into a prolonged coma, suffered catastrophic neurological damage, lost most of her vision and speech, and required lifelong care. She died in December 2023 at age 50. Police identified her roommate Sun Wei—who had authorized access to thallium compounds for undergraduate research—as the primary suspect and questioned her in 1997. Sun was never charged. The investigation went cold amid reports of delayed reporting by the university, missing evidence (including items from Zhu’s dorm), and speculation about Sun’s family connections. Zhu’s supporters and many Chinese internet users have long argued that envy of her academic, musical, and personal standing supplied the motive. The case remains officially unsolved.
A System That Produces Extreme Competitive Behavior
Cases such as these illustrate a recurring pattern among some individuals shaped by the Chinese Communist Party’s educational and social system: intense, zero-sum competition, weak internal restraints against harming rivals, and a willingness to destroy another person’s health or career when personal advancement or prestige is threatened. Under the CCP, moral formation is subordinated to political loyalty and material success; envy is common, accountability for the well-connected is often absent, and intellectual property is treated as something to be taken rather than respected. When those habits travel abroad on student visas, American laboratories and colleagues become targets. The Wyoming case is not an isolated anomaly; it is the predictable export of a political culture that systematically undervalues individual rights and basic ethical limits.
Wang has no attorney listed in court documents. The University of Wyoming has stated its commitment to campus safety. The victim continues to experience symptoms.
