Victim Releases Spy-Cam Footage as Poisoner Seeks Felony Expungement

Key points

• Yuan released surveillance videos showing Xu pouring a substance into her water bottle in 2019, which led to his arrest and conviction for poisoning.
• Xu, a former senior materials engineer, pleaded no contest to one count of poisoning in 2023 after facing charges of premeditated attempted murder.
• The Alameda County district attorney objected to Xu's expungement request, but California law mandates dismissal if probation conditions are satisfied.
• Yuan suffered severe symptoms including hair loss and vomiting, with water samples testing at 3.5 million times the federal cadmium limit.
• Xu completed his two-year probation in March 2026; the expungement hearing is scheduled for Monday in Alameda County Superior Court.

Background

This case highlights ongoing debates regarding plea deals and expungement laws in California. Previous coverage noted that Xu faced a lenient sentence under District Attorney Pamela Price, who was later recalled by voters partly due to such deals. The incident occurred at Berkeley Engineering and Research, where both individuals worked as metallurgists. Yuan’s recent research paper on cadmium’s long-term health effects underscores the lasting impact of the poisoning on her family, including her father’s recent death.

How outlets are covering it

Fox News emphasizes Yuan’s release of the video as a 'last resort' against a system she believes failed her, focusing on the emotional toll and the immediate threat of expungement. The San Francisco Standard provides a detailed timeline, highlighting the contrast between the severity of the crime (attempted murder charges) and the leniency of the plea deal, as well as the legal constraints forcing the judge to potentially grant the expungement. Both sources agree on the facts of the poisoning and the legal process but differ in emphasis: Fox focuses on the victim’s agency, while the Standard critiques the judicial and prosecutorial outcomes.

Why it matters

The case underscores the tension between victim advocacy and statutory expungement laws in California. It raises questions about the adequacy of restitution and sentencing in cases involving toxic substances. Yuan’s public disclosure of evidence aims to prevent the conviction from disappearing from background checks, potentially affecting Xu’s future employment and public safety. The outcome may influence future discussions on criminal justice reform and victim rights in expungement proceedings.

What to watch

The expungement hearing is scheduled for Monday at 9 a.m. in Alameda County Superior Court. Yuan plans to attend and speak under Marsy’s Law. The judge must decide whether to grant the dismissal despite the district attorney’s objection. If granted, Xu’s conviction will remain on his record for law enforcement but may not appear in standard background checks, potentially impacting his future career and public perception of the case.
