President Jacob Zuma's wife Sizakele Zuma has made an impassioned plea to the government to stop the murder of police officers. Speaking at the memorial service of Sergeant Mzwakhe John Magwaza, 42, a presidential protection unit guard who was stationed at the Nkandla homestead, MaKhumalo said she was saddened by Magwaza's murder. Like many other of her husband's bodyguards, he had become like a child to her.Magwaza was shot dead at his home in Entumeni - a missionary settlement between Eshowe and Nkandla - early last Sunday.His funeral was yesterday.story_article_left1"I am very saddened by this, my heart is sore. These children are like mine. We all depend on the police to protect us, why then kill them? Why are we finishing them? This should stop, I beg. The authorities should stop this," MaKhumalo said.There are questions about the killing of Magwaza, whose fiancée, Khona Mgwaba, described it as "unprovoked".Some of Magwaza's colleagues said it seemed as though a cloud of bad luck was hovering over Zuma's guards. "Njinji [Magwaza] is the fourth guard to die," said one at the memorial service.The man said Zuma buried his favourite guard, Bongumusa Maphumulo, who died after an illness in 2011. Phinda Thomo died under mysterious circumstances in the same year. "In the 1990s the president also lost Dumakude [Vusi Shange]."The bodyguard said Shange was an experienced ANC combatant who had been drafted into the ANC security unit and had guarded Zuma when he was KwaZulu-Natal's MEC for economic development.Colonel Mandlenkosi Xolo, section commander of the presidential protection unit, said he was saddened to lose yet another vital member of the unit."The truth will come out. Unfortunately, there's no longer a death penalty in this country because it was used for all the wrong reasons," he said.story_article_right2Recounting the minutes before Magwaza's death, his fiancée said they were woken up by a noise outside at about 1.30am."Muzi [Magwaza] phoned Eshowe police and his colleagues, telling them we were under attack," she said.The attackers tried to set the thatched rondavel on fire ."The noise died down and he went outside. But as he was talking to the neighbours he was shot several times from the back. We all ran and took cover until the police came," she said.Magwaza's brother Mkhombeni Mthembu said the family did not want to speculate on the motive for the murder. His brother did not have any known enemies.Magwaza's killing comes just three months after KwaZulu-Natal premier Senzo Mchunu's bodyguard Xolani Nkosi was gunned down.No arrests had been made yet, police said...
