Five children were found dead inside a freezer on Tuesday evening in Kakamas in the Northern Cape, police said.
Police opened an inquest case after the children aged between three and seven-years-old respectively were found dead inside a freezer.
The deceased were cousins.
“It is alleged that on 19 January 2016 at about 18:00, the grandmother of the children found them all suffocated inside an old freezer in their yard,” said police.
“It is believed the freezer locked accidentally while the kids were playing inside it.”
In February last year Melice Jacobs was arrested and is facing three counts of murder and one count of concealment of birth after police found the bodies of the infants in a freezer in her home in the New Brighton informal settlement, near Mthatha, Eastern Cape.
One of the bodies found in the house was allegedly still in the early fetal stage.
One body was found in the freezer compartment of a fridge and the other three in a separate freezer.
Jacobs reportedly admitted to knowing the bodies had been there and that they had been there for a long time.
Upon her arrest, police said Jacobs was initially going to confess, but later declined to do so.
Police said one of the frozen infants was allegedly strangled to death using a shoelace.
Police received a tip-off about the bodies while Jacobs was in Johannesburg.
She alleged her deceased boyfriend was the father of the babies and she was their mother.
