Engel's testimony formed part of pre-sentencing procedures in the murder trial currently underway in Ventersdorp, Beeld newspaper reported on Tuesday.

Engel told the court that he had interviewed Martie Terre'Blanche in June to determine the impact of her husband's murder on her family.

"I want to reclaim my perspective on life, this court case has been a huge setback. I do not hate the accused, and I'm not bitter... they crushed me and they murdered my husband in the most barbaric way," she told Engel.

She said she still died "ten deaths" when she drove past his farm, Witrandjiesfontein, where the murder happened.

She also said that even if the accused escaped justice, they would still eventually have to face divine justice. Engel then told the court that the murder of a loved one was one of the most traumatic things a person could experience.

Chris Mahlangu, 30, has been found guilty of murdering Eugene Terre'Blanche in his house on 3 April 2010, while Patrick Ndlovu, 18, who also worked on the farm at the time of the murder, has been found guilty of robbery with the intent to steal.

The pre-sentencing procedures are set to continue on Tuesday.
