Pieter was killed on their farm at Hennenman in the Free State at the end of last week, and his son, Eddie (26), was shot in the neck after they were attacked in their farmhouse.
SA Updates have learned that Eddie became “brain dead” at Milpark Hospital in Johannesburg after having a setback on Sunday night.
Eddie apparently came across the attack when he arrived at the house on their farm Zwartpan.
A worker from the family came across the father and son in the farmhouse at around 05:00 on Friday after the farmer’s wife, Antoinette, called her and asked her to investigate. She was not home at the time of the attack and could not get hold of them, after which she approached the worker.
One of four suspects arrested on Friday in connection with the farm murder of Pieter Hills (56) and the attack on his son, appeared briefly in the town’s magistrate’s court on Monday.
