"Tsafenadas, who had assassinated the South African prime minister Hendrik Verwoerd"

 Dimitri Tsafendas stabbed to death the "Architect of Apartheid", South African prime minister Dr Hendrik Verwoerd, in a frenzied attack in 1966. The news startled both the nation's black and white communities, especially when it became known that Tsafendas was following instructions from a giant tapeworm.

He was found unfit to stand trial by reason of insanity. Tsafendas was committed to detention in a secure mental institution but served much of his sentence of death row.

The illegitimate son of a Greek and his mixed-blood maid, Tsafendas was sent as a child to a grandmother in Egypt. As if rejection by his parents wasn’t enough, he was taunted at school for his dark skin and given the name ‘Blackie’. Whatever his mental state at the time of the assassination, after years on death row he was certainly insane in later life.
