Summary
In what prosecutors are calling one of Wisconsin’s most disturbing poison plots ever uncovered, 43-year-old Paul VanDuyne Jr. and his girlfriend Andrea Whitaker face a mountain of charges after allegedly stalking and trying to kill two women he briefly dated. Their weapons of choice? Cyanide, thallium, hydrogen sulfide, and even abrin—a toxin more lethal than ricin.
It began with dating apps. Two women, each believing they had dodged a creepy connection, suddenly found themselves targeted in a campaign of chemical warfare. From poisoned water bottles and tampered air vents to planted trail cams and texts blaming them for fake suicides—this wasn’t obsession. It was a murder plot months in the making.
One woman remains paralyzed in a wheelchair. Another narrowly escaped. FBI agents found a toxic lab in VanDuyne’s van—including vials, a grinder, and rosary peas. Whitaker, trained in pharmacology, was allegedly the mastermind behind the dosages.
They stalked their victims across county lines. Planted poison in garages, cars, and even through air ducts. Their bail? $10 million and $4 million. Their charges? Attempted first-degree homicide, stalking, battery, and more.
This case blends science, psychology, and absolute horror. How far would someone go to control a person who never wanted them to begin with?
