Parents and concerned parties are protesting outside Parktown Boys' High School on Tuesday.
JOHANNESBURG - The family of Parktown Boys' pupil Enoch Mpianzi is one step closer to finding out what happened to him.
An autopsy has now been completed.
The 13-year-old Grade 8 pupil drowned during an orientation camp in the North West last week.
On Tuesday, some parents and concerned citizens staged a silent protest outside the school.
Police say preliminary results suggest none of the boys was wearing a life jacket when the raft they were on capsized.
Officers say the case is now 70 percent complete with just two statements outstanding.
They've confirmed the school only alerted them to the incident a day after it happened.
