Man dies years after co-worker poisoned his lunch

Klaus O poisoned his co-workers' sandwiches

Thursday, January 9, 2020

A man in Germany has died four years after being poisoned by a colleague and falling into a coma.

The 26-year-old was the victim of a man identified only as Klaus O, who frequently peppered his co-workers' sandwiches with mercury, lead and cadmium over several years.

The victim was just a trainee at the metal fittings company he and Klaus O worked at when he fell into a coma after unknowingly ingesting mercury.

The 57-year-old's actions left two other workers with chronic kidney damage from lead and cadmium poisoning, which has heightened their risk of developing cancer.

Klaus O was arrested in May 2018 after the company's surveillance video showed him putting a suspicious powder on a colleague's sandwich.

When authorities the man's home, they found a private laboratory containing substances Judge Georg Zimmermann called "more dangerous than all combat agents used in the Second World War".

He was found guilty of attempted murder and sentenced to life in prison last March.

Prosecutors said they believed he wanted to see his colleagues' physical decline, however Klaus O refused to speak during his trial to confirm his motive.

Judge Zimmermann said his crimes were as serious as homicide, and ordered the man to be detained in prison after completing the life sentence - which is around 15 years in Germany - because he posed a danger to the public.

Klaus O has appealed against the sentence.
