Prosecutors are preparing to lead the last of their evidence against Johan Kotze, a man referred to by many as the Modimolle Monster.
Kotze is accused of murdering his stepson, 19-year-old Conrad Bonette.
He is also also accused of orchestrating the gang rape and torture of his wife, Ian Bonette.
These incidents allegedly occurred in Kotze’s house in Modimolle in 2012.
The accused has fired his defense advocate after Bernhard Bandjies suggested his former client may have been suffering from temporary insanity.
But it remains unclear if the accused’s new advocate will persist with that argument.
Kotze’s co-accused Andries Sithole, Pieta Mohlane and Frans Mphaka said Kotze threaten to kill them if they did not rape his wife.
But the trio has denied that they were physically able to carry out the rape.
Crime scene photos show the bed where Bonette said she was sexually and physically tortured for hours.
She has testified that the men raped her and they did nothing when her estranged husband mutilated her.
Kotze’s lawyers previously argued that Bonette’s body showed little signs of being mutilated.
The lawyers suggested that the woman had exaggerated her injuries.
These claims forced the state to call medical experts to the stand.
Prosecutors are expected to close their case after that testimony and that is when Kotze will finally have his chance in the witness box.
