The South African Human Rights Commission (SAHRC) is set to investigate several unsolved murders in the small town of Klawer in the Western Cape.
This follows claims that the self-confessed murderer of 13-year-old Jerobejin Van Wyk, could be guilty of more crimes.
The 56-year-old man was arrested following a search of his house, where police found human remains in a drainpipe.
In a shock confession to his lawyer, Daniel Smit also admitted to other satanic crimes in the province.
Smit will appear in court again on April 26.
