Ina Bonette, the estranged wife of the so called Modimolle Monster, is back on the witness stand on Wednesday.
Bonnette bravely faced her alleged attackers on Tuesday when she testified in camera
about her harrowing ordeal at the hands of three men and her ex-husband Johan Kotze in January.
They are accused of murdering her 19-year-old son, Conrad, and brutally torturing, raping and sexually abusing her.
Kotze's co-accused, Andries Sithole, Pieta Mohlane and Frans Mphaka have pleaded not quilty to all 17 charges, claiming that they had been forced at gunpoint to commit the brutal assault.
In her evidence, which was held in camera, Bonnette told the court that during her ordeal Kotze had used a pair of pliers to twist one of her nipples. She also told how Kotze had forced the three others to rape her and mutilate her using nails, a screwdriver and an angle-grinder.
Bonnette faces cross-examination on Wednesday by defence counsel.
