The National Prosecuting Authority NPA says it has prima facie evidence to charge scholar transport driver Ayanda Dludla, 22, with 14 counts of murder instead of culpable homicide.
Dludlas vehicle collided with a truck on the Golden Highway in Vanderbijlpark, Vaal, on Monday, killing 14 pupils.
Police on Thursday said the death toll had increased from 12 to 14 after two pupils died in hospital.
