South African prime minister Hendrik Verwoerd was assassinated in Cape Town in 1966. As the chief architect of South Africa's apartheid regime, Verwoerd was widely loathed. Ironically, however, the murder was not racially motivated. The culprit was Dimitri Tsafendas, who insisted that he had been ordered to assassinate Verwoerd by the tapeworm in his stomach!
[Tapeworms range in length from .04 inches to more than 50 feet.]
