PRETORIA - Ina Bonette's ex-husband, Rex Bonette, took to the stand on Wednesday, in what has been dubbed the Modimolle Monster trial.
Bonette provided evidence supporting the defence of murder suspect and co-accused, Pieta Mohlane and Frans Mphaka.
Bonette was called to testify by Mohlane and Mphaka, who claim that Kotze forced them to sexually assault Ina.
Kotze, Mohlake, Mphaka and the other co-accused, Andries Sithole, pleaded not guilty to raping and attempting to murder Kotze's ex-wife, Ina, in January last year.
They also denied involvement in the murder of her 19-year-old son Conrad.
Ina Bonette however maintains that the men were willing participants in the attack.
However, Rex Bonette testified that his ex-wife had spoken to him on the day after the attack, and told him that Kotze had threatened to shoot his co-accused if they didn't rape her.
The state is now cross-examining Rex Bonette, who insists there is no way he could have been mistaken about what Ina said to him.
