The Western Cape police are investigating the circumstances under which three brothers died in their home in Knysna.
It is believed that the two younger boys, aged 10 and 11, were visiting their 20-year-old brother at his home in Nekkies.
They reportedly went to sleep on Thursday night, however when their mother went to fetch the boys on Friday morning, she discovered their bodies on the floor of the room.
Police spokesperson Chris Spies said: “Emergency personnel responded to the incident where paramedics later declared the trio dead on scene. Circumstances surrounding the deaths are under investigation. Crime scene experts combed the scene for clues. The debris of the fire that was made in a tin container was found on the premises.”
A post-mortem will be conducted early next week to determine the cause of their deaths.
