She was speaking at a prayer day in Diepsloot, where a seven-month-old baby was found dead on Sunday, following the recent deaths of two cousins, two and three-years-old, and a five-year-old girl.
She was accompanied by Johannesburg mayor Parks Tau and religious leaders. Xingwana said government would ensure justice was done.
“We pledge solidarity with the community. We will leave no stone unturned. Government cannot do much without the support of the community,” she said.
Tau said he was in the area on Sunday when the baby was found dead.
According to The Star, the baby’s mother reported the death to the police early on Sunday morning, claiming her child had been mutilated by rats. When police arrived on the scene, the woman had disappeared.
Pathology tests apparently confirmed that rats attacked the child.
But, Captain Tsekiso Mofokeng said a case of murder was being investigated.
“We have registered a case of murder, but initially it was an inquest,” Mofokeng said.
Police arrived to find the baby’s body with a foot missing from the body.
“Further investigations informed police that [the foot] was bitten off by rats.”
Police were still awaiting the results of the post mortem to definitively determine the cause of death. Mofokeng said the baby’s mother was missing and had still not been located by Monday morning, contrary to media reports that she had reported the matter to police.
In October, Yonelisa Mali, two, and her cousin Zandile Mali, three, were found dead in a toilet cubicle by a resident.
After the murders were discovered, Diepsloot residents stoned cars and burnt tyres in the street outside the local police station in protest.
A 29-year-old man faces charges of murder, rape and kidnapping in connection with the cousins’ deaths.
In September, five-year-old Anelisa Mkondo was found dead in the same area.
National Prosecuting Authority spokesman Medupi Simasiku said the police were still investigating Mkondo’s case.
