Engineer releases video showing coworker adding substance into her drink, alleges she was poisoned

A Berkeley engineer has released surveillance footage showing her coworker, David Xu, adding a substance to her drink. The woman alleges she was repeatedly poisoned for months, nearly resulting in her death. Despite being charged in 2019 with premeditated attempted murder, Xu received probation after pleading no contest to a single felony. The victim is publicly sharing the spy-cam video to express her frustration over the legal outcome and the severity of the crime.
