Johannesburg - The grandfather of two murdered 8-year-old cousins says the children used to call their alleged killer uncle. “He was like their own, they used to call him uncle whenever he came to visit us,” Lelala Motaung told News24 on Wednesday, in the flat in Germiston where the cousins lived.He used to visit the Motaung family often and was served meals.Motaung said his relatives called him around 21:00 on Sunday to tell him the children were missing. He packed his bag and rushed to Germiston to help find them. The 63-year-old arrived from Qwa-Qwa on Monday morning. A shop owner provided the first clue about what had happened with CCTV footage taken outside his shop, which is next to the cousins' flat.The footage shows Kefilwe Motaung, wearing a pink top, holding the hand of her alleged killer. She glances over her shoulder at her cousin Thato Motaung. Shortly after, Thato runs after her.Motaung said he was able to identify the man.><br _moz_dirty="" />“When we eventually found him, he was beaten up by community members like nobody’s business,” he said. The man however refused to say where the children were.The man apparently confessed after he was told about the CCTV footage. He directed them to an abandoned building near a railway line, close to the Germiston mortuary. “We rushed to the empty building, but it was too late. They were dead,” he said.The two children had been bludgeoned to death and their bodies hidden under plastic covers. “The family is not coping at all; it is a very difficult time for us. I am still battling to eat,” he said.A resident living in a house surrounded by trees, near the crime scene, said they were disgusted by the murders. “The police should have released the man, so that we do to him what he did to the kids,” Excellent Hlongwane said.“The man is still alive, he will get food in jail, and the kids are dead today,” he said.Motaung said they would remember the children as friendly and playful. The man was expected to appear in the Germiston Magistrate's Court on Thursday, according to a police officer who asked not to be named.
