Johannesburg - A 14-year-old boy who allegedly hacked his mother, two siblings, and his grandmother to death appeared in the Daveyton Magistrate's Court on Friday.
"The case has been postponed to 20 August," said National Prosecuting Authority spokesperson Medupe Simasiku.
This was to allow for further investigation and for a post mortem report to be finalised, he said.
The teenager, who is being kept in a place of safety, allegedly used an axe to kill his mother, 42, and two siblings, aged seven and three-months-old, on 24 May. His grandmother was injured in the attack and admitted to the Far East Rand Hospital, where she died on 5 July.
The youth's two other siblings, aged eight and nine, escaped and alerted neighbours. He fled the scene, but was later arrested and charged.
