Lab Scientist Accused of Poisoning Co-Worker

A University of Wisconsin–Madison laboratory worker reportedly noticed a strange odor and taste coming from a personal water bottle, leading to an investigation that authorities later said involved an alleged poisoning attempt by a co-worker.

According to a criminal complaint, the affected employee told the authorities that the bottle had an unusual smell and tasted off when he drank from it. He also reportedly noticed that his shoes carried a strong chemical odor. The situation was reported, prompting a response from campus authorities.

Investigators later alleged that a fellow employee had introduced laboratory chemicals into the victim’s belongings. The substances were believed to include paraformaldehyde, chloroform, and Trizol. Testing of the water bottle reportedly showed extremely high levels of chloroform, with officials noting the readings were too high to measure accurately. Authorities stated that such exposure could pose serious health risks.

The suspect allegedly admitted to both the co-worker and a supervisor that he had tampered with the items. In reported communications, he apologized and acknowledged informing the victim directly. Authorities said he later told investigators that he had placed small amounts of chemicals into the water bottle and inside the victim’s shoes.

According to the complaint, the suspect and the co-worker had worked together for several years. He allegedly claimed that tensions developed over time, including feelings that the co-worker had become disrespectful after receiving promotions. Authorities said he also admitted to researching harmful chemical dosages online, including through ChatGPT, before the incident.

The suspect was arrested several days after the initial report and later faced felony charges, including recklessly endangering safety and tampering with a household product. University officials stated that he had been placed on administrative leave, and his access to campus resources had been revoked while the investigation continued.
