Berkeley Engineering & Research: A woman who was secretly p*isoned by her coworker, David Xu, shared hidden-camera footage that helped investigators catch him. The incident took place around 10 years ago, and the video reportedly captured evidence of his actions. According to officials, Xu used cadmium to p*ison her over 18 months.
Xu is now appearing in court, where he will ask a judge to dismiss his felony conviction. The case has drawn attention again as the legal proceedings continue.
