Their case was postponed for Mokgadi‚ Maluleke and Malatjie to get legal representatives and for Mlambo and Ligege's formal bail application.
Greg‚ 57‚ Melanie‚ 51‚ and Rakiel Naidoo‚ 23‚ disappeared from their home in Northcliff‚ Johannesburg‚ after the robbery earlier this month.
Police later found three burnt bodies that were believed to be theirs in Centurion.
Initially six men were arrested in connection with the case‚ but charges were withdrawn against the sixth man due to a lack of evidence.
