Dr Prudence Buthelezi says 80-year-old Dumisile Mahlangu, who was locked in her home and set alight by the community of Mbuzini after she was found wandering a neighbour's house naked at night, could have been suffering from dementia or Alzheimer's disease. She was accused of practising witchcraft.
