David Xu, a metallurgist at Berkeley Engineering and Research, was caught on camera allegedly poisoning his colleague's water bottle with cadmium between 2017 and 2019. The footage, recorded by the victim, Rong Yuan, showed Xu putting a substance into her water bottle. Yuan experienced severe health issues, including frequent vomiting requiring emergency hospital treatment.
The poisoning was exposed in early 2019 after Yuan installed a hidden camera at her desk. Xu was arrested in March 2019 and pleaded no contest to a single felony count of poisoning in September 2023, receiving probation. Yuan, who suffered long-term health effects, sought nearly $500,000 in restitution but was only ordered to pay $7,058. Xu is now seeking to have his felony conviction dismissed under California's expungement process.
