Man Kills 21 Of His Co-workers With Poisonous Sandwiches.

A 57 year old German man was sentenced to life in prison for poisoning his colleagues' sandwiches with dangerous heavy metals. 21 of his victims died and two victims have been left with serious kidney damage and a third is in a vegetative state after falling into a coma.

Even though the man refused to speak during his trial and the motive for his actions is still unclear. However, a mental health expert for the prison service told the court that the defendant wanted to see how the poison would affect his colleagues, like a scientist performing tests on a rabbit.
