Former South African first lady, Marike de Klerk, was found murdered at her luxury beachfront apartment in Cape Town. The ex-wife of former South African president F.W. de Klerk was stabbed from behind and strangled to death. Her death shocked the nation and the world. Luyanda Mboniswa, a security guard at the complex accused of her murder, pleaded not guilty to all charges levelled against him. Though Mboniswa later alleged in court that the killing was masterminded by De Klerk's dance teacher, Justice Hlope ruled that there was no such evidence to sustain the claim. Mboniswa was found guilty on counts of housebreaking, robbery and murder by Judge President Hlope.
