The Florida chemistry whiz charged with injecting opioids underneath his neighbor’s front door — because of a noisy toilet seat — used the laboratory at his university to carefully mix the dangerous toxins, according to court papers obtained by The Post.
Xuming Li, 36, used a “laboratory on the University of South Florida campus to mix and load liquid syringes on multiple occasions with the intent to harm residents of the condominium,” the breach of contract filing by the building’s owners association states.
Li was a Ph.D. chemistry student at the university until summer 2023, USF confirmed to WFLA.
The chemist was arrested on June 27 after his neighbor, Umar Abdullah, caught him on a hidden camera crouching down and squirting a clear liquid into a crack in the door frame.
A hazmat test revealed the “liquid chemical agent” contained a combination of methadone and hydrocodone — both opioid pain medications.
