Kotze was traumatised - psychologist
A clinical psychologist says Johan Kotze cannot be held responsible for his alleged crimes.
PRETORIA - A clinical psychologist in the so-called 'Modimolle monster' case on Friday told the North Gauteng High Court that Johan Kotze fled the scene of the crime because he was traumatised.
He admitted to torturing and mutilating his estranged wife Ina Bonnette in January 2012.
But Kotze denied killing his stepson, Conrad Bonnette.
Kotze also denies orchestrating Bonnette's gang-rape.
Three of his workers also face charges.
Speaking in court on Friday, Dr Tertia Spangenberg said Kotze's actions that followed the attack proved he was not in a rational state of mind.
She said not only did Kotze leave evidence behind, but also a living witness who could tell the story of what happened.
Spangenberg also backed Kotze's claims that he could not recall significant details of the day in question saying, "People who commit violent acts are often traumatised by them."
She added Kotze suffered from a narcissistic personality disorder and that he could not be held responsible for his alleged crimes.
