Griekwastad case: Byleveld advises cops
Johannesburg - Former detective Piet Byleveld has given advice to cops investigating the puzzling murders of a family on a farm in Griekwastad over Easter.
Volksblad reported that Byleveld said it was crucial to establish the motive for the murders.
He also said the scene of the crime had to be properly investigated.
The bodies of Deon Steenkamp, 44, his wife Christel, 43, and their daughter Marthella, 14, were cremated on Wednesday after a private service at a secret location in Kimberley.
The only surviving member of the tragedy is believed to be staying with family in the Northern Cape and is not at school.
Earlier reports indicated that police believed the 15-year-old to be a suspect in the case. Rumours also circulated about the teenager's argument with his father on the day of the murders.
A legal expert said it was necessary to test the hands of all of the deceased for gunpowder residue, otherwise questions about the murderer would never be answered.
Questions have been raised about the way in which police investigated the crime scene on the farm and that permission had been given too early to family members to clean up the house.
The surviving son was allegedly also allowed to wash himself soon after reporting the murders of his family members.
