Tödliche Verbindungen - Deadly Connections

The Lunchbox Poisoner [EN]


Listen Later

Heavy metals, a factory cafeteria – and a coworker who watched

In this episode:

The Case: The company Ari in Schloß Holte-Stukenbrock, Germany. Klaus O., a machinist and family man. Years of poisoning. A vigilant student worker, a hidden camera, an arrest. The 2018/19 trial and verdict: life in prison with subsequent preventive detention.

The Chemistry: Lead acetate, mercury (specifically organic compounds including dimethylmercury), and cadmium. Why all three act cumulatively. How they damage the body. Why the clinical picture looks like almost anything except poisoning.

The Detection: ICP-MS as a forensic method. Why the tools existed – and nobody thought to use them.

The Treatment: Chelation therapy for lead and inorganic mercury. Why organic mercury compounds are an entirely different, almost hopeless category. Why cadmium still has no effective treatment today.

Victims in this episode:

Nick N.: student worker, 26 years old, died 2020 from the effects of the poisoning
Udo: surviving victim, permanent kidney damage, ongoing dialysis
